The difference between auto parts and spare parts:

Car accessories

Auto parts refer to parts that are not frequently replaced. The spare parts department does not need to stock up. If stocking, it may produce Class C, Class D, and inventory, but this part of the parts can be ordered through the manufacturer's regular orders. Car owners are rarely replaced, such as: exhaust pipes, oil pans, headlights, glass, engine covers, etc.

Car spare parts

Vehicle spare parts refer to the parts that need to be replaced in general. The spare parts department is the spare parts that need to be stocked. The parts that the majority of the owners often need to replace, such as: air conditioning grid (scientific name: air filter), oil grid (scientific name: oil filter) Air conditioning grid (scientific name: air conditioning filter) Gasoline grid (scientific name: gasoline filter) Spark plug engine oil, these are car spare parts.

Basic Knowledge About CAR ALARM

Most of us know car alarms are an important part of a vehicle security system, but how do car alarms work? In this guide, we’ll look at how car alarms work and the technology that they use to keep your vehicle safe. Read on to learn more about the technology that goes into a modern car alarm.

What is a Car Alarm?

The main purpose of a car alarm is to prevent the theft of your personal belongings within the vehicle and to prevent the theft of the vehicle itself. That said, not all car alarms are the same. Some are triggered by different actions and have different features. OEM Car alarms tend to have basic features compared to aftermarket systems.

OEM vs Aftermarket

OEM car alarms typically come with basic car alarm features. These features are usually limited to 1-way remote door locks, 1-way remote start, starter/injector kill, and horn trigger. Most are designed only to prevent vehicle theft and are not designed to protect your belongings.

Aftermarket alarm systems offer a wider array of components and features that can be added to beef up your security. The addition of an aftermarket car alarm using just the basic features can significantly increase your vehicle’s security.

Components of a car alarm

Car alarms are made up of several different parts. Broken down into the most basic categories, today’s car alarms are made up of a computer, a receiver that responds to your keycode, a loudspeaker and several different sensors.

The way a car alarm works is simple: when the alarm is switched on and a sensor receives a response, the alarm sounds. When the sensors don’t record any unusual activity, the car alarm remains active but silent and unnoticeable.

Older car alarms usually only included one or two sensors – typically a door sensor and a tilt/shock sensor. Today, car alarms – particularly alarms fitted to expensive vehicles – can include anywhere from two to ten different sensors.

Car Alarm sensors

Modern car alarms are designed to respond to a variety of different security threats that can lead to car theft or other car crime. These include the risk of a break-in via a car door, damage from impact and even loud noise in the vicinity of the car itself.

All of these sensors are connected to the alarm’s computer. If one of the sensors is activated by a potential car thief, the sensor sends a signal to the computer and the alarm is activated, preventing theft or damage.

Door sensors

Door sensors are the most common sensors used in modern car alarms. When the alarm is active, the sensors send a signal to the alarm. If a car thief opens the door, the alarm sounds.Since most car thefts require the thief to break open your car’s lock and enter the vehicle, door sensors are very effective in deterring theft. However, they usually don’t prevent a thief from breaking a window to enter your car or towing it away.

Shock/Impact Sensors

Door sensors can stop a thief from breaking open your car’s door, but can they stop someone from breaking a window to enter your car? Shock sensors detect hits and impacts around your car, such as the shock of someone breaking a window.

Shock sensors work by detecting when an impact occurs. If someone smashes one of your car’s windows, the shock sensor detects this impact and transmits an alert to the alarm’s computer. The car alarm is then activated.Since shock sensors sound your car alarm whenever any impact occurs, they might occasionally activate accidentally. If someone accidentally opens their door into the side of your car while parking, the impact could be strong enough activate the alarm.

Microphone sensors

Since your car’s door alarms prevent thieves from picking its locks and the impact sensors prevent them from smashing a window, thieves have fewer options to get into your car and drive it away.

However, they can still break a window using less impact, letting them get into the car. Microphone sensors prevent thieves from breaking into your car by monitoring for loud, sudden noises such as a window breaking.

Modern microphone sensors are designed to account for the ambient sound level in the area close to your car. This means that in noisy areas, the sensor will listen for a sudden change in sound level that could indicate a break-in taking place.

Tilt sensors

Thieves don’t necessarily need to break into your car in order to steal it. A car thief with a tow truck could simply lift up your vehicle and tow it away in order to strip it for parts and sell it to someone else.

Tilt sensors prevent thieves from towing your car away by monitoring the angle of your car. If your car’s angle changes, the tilt sensor sends a signal to the computer, which activates the alarm.

Modern tilt sensors use mercury, which conducts electricity, to monitor a car’s tilt level. If the car’s angle suddenly changes, the mercury flows to one side and causes the switch to activate, sounding the alarm.

Proximity sensors

Proximity sensors, which are also known as perimeter scanners, work by scanning the area around your car. These types of sensors are typically found in newer cars, particularly high-end models.

Since proximity sensors monitor activity around your vehicle, they can often trigger false alarms. Most modern proximity sensors are designed to calculate how close an object is to your car and only activate if it becomes extremely close.

Difference between Ethernet cables:Cat7/Cat8/Cat6/Cat6a

Type of Copper wire cable

The functions and performance of the cable differ depending on the Cat5e, Cat6, Cat6a, Cat7, Cat8, and standard. It's a good idea to choose the right LAN cable for your situation.

Cat8

Cat8 based on the new standard of ANSI / TIA-568-C.2-1 can transmit data of 40Gbps within 30m and can communicate with a maximum frequency of 2000MHz. The backward compatible Cat8 cable is compatible with the RJ-45 connector and is used for small and medium-sized enterprise wired / wireless LAN and switch-server interconnection.

Cat7

The Cat7 standard is capable of transmitting 10 Gigabit Ethernet over 100m of copper wire, and can transmit up to 600MHz. Furthermore, it seems that data transmission of 40 Gbps within 50 m and data transmission of 100 Gbps within 15 m are possible. The Cat7 cable is shielded to prevent communication problems caused by electromagnetic waves in offices and factory sites.

Cat6

Cat6 cable has a maximum operating frequency of 250MHz and can support transmission speeds of 1000Mbps. Compared to Category 5, it has stricter noise resistance and stronger core, and can be expected to have the effect of preventing data corruption. Cat6 is upward compatible with Category 3 and supports the same up to 100m segment distance as Category 5, but with 10GBASE-T the cable length is up to 55m.

Cat6a

Cat6a has a frequency of 500MHz, which is twice that of Category 6, and can support 10BASE-T data transmission over 100m segment distances. It has excellent noise immunity and core as it fully demonstrates the performance of 10GBASE-T. However, Cat6a cables with claw breakage prevention covers are relatively inflexible and are often used as industrial LAN cables.

Cat5e

An improvement over Category 5 cable, its TIA / EIA-568-B standard replaces Category 5 TIA/EIA-568-A and was defined as a new standard in 2001. Cat5e cables are designed for operating frequencies up to 100MHz and can support transmission speeds up to 1000Mbps over 100m segment distances. The Cat5e cable contains 4 pairs of 2 core wire pairs, which are often used for indoor or home LAN wiring.

The Difference Between Cat6 vs. Cat6A Ethernet Cable

Category 6 (CAT6) has a reputation for stable transmission and reception despite high-speed communication. On the other hand, in recent years, the use of category 6A (CAT6A) has also attracted attention.

 In this article, I will explain the differences between CAT6 and CAT6A and what kind of environment they are recommended for.

   The big difference is "correspondence speed" and "transmission band"

The biggest difference between Category 6 (CAT6) and Category 6A (CAT6A) is in "correspondence speed" and "transmission band".

 CAT6 supports 1 Gbps, while CAT6A supports 10 Gbps. Regarding the electrical band, CAT6 is 250MHz, while CAT6A is 500MHz.

 The larger the number, the faster the response speed and the larger the electrical bandwidth. Therefore, CAT6A is faster than CAT6 and has a larger bandwidth.

 Differences in structure as seen by differences in categories

CAT6 and CAT6A also have different structures. This time, we will compare using Panduit's [TIA/EIA/ANSI] standard cable. (The cables of Fuji Electric Wire Co., Ltd. and Telecommunications Kogyo Co., Ltd., which produce licenses, are equivalent cables.)

 ① Comparison of outer diameter and internal structure

The outer diameter is about 6.3 mm for CAT6 and about 7.7 mm for CAT6A, and CAT6A has a thicker structure.

 The internal structure is cross-shaped, but CAT6A has "presser roll (LDPE)" and "AX tape" added. It is possible to prevent noise with AX tape while taking measures against loss by interposing a cross.

 ② Comparison of core lines

Next, we will compare with the "AWG standard" that indicates the thickness of the core wire of the cable.

 The AWG standard is 0.5105 mm for CAT6 and 0.5740 mm for CAT6A. You can see that CAT6A is slightly thicker.

 This difference in thickness is related to the presser rolls and AX tapes that are not added to the CAT6 mentioned above. In particular, CAT6A is thicker than other cables, so it is difficult to roll it into small pieces, which can be difficult when passing through narrow pipes.

  ③Comparison of connectors

The parts that make up the CAT6 and CAT6A connectors are almost the same, and the same can be used for the termination tool. However, the parts that are actually used are different, just because they are similar.

 Each recommended environment

As mentioned above, there are various differences in performance and structure between CAT6 and CAT6A. Therefore, there are differences in the optimal environment for use.

 CAT6 is recommended for home use. Even when connecting several devices at the same time, you can use it comfortably without slowing down. In addition, it is possible to connect from the router of the optical line to the hub in an environment where there are several PCs. Since it is upward compatible with categories before CAT6, CAT6 is recommended if you are worried about category 5e (CAT5e).

 On the other hand, CAT6A is recommended not only for home use but also for introduction in companies such as offices and stores. CAT6A can connect to a server that supports 10G connection, and can connect to a hub and server, and is especially suitable for watching videos on LCD TVs and utilizing online content. Also, when using CAT6A, be sure to check whether the usage environment supports 10Gbps connection.

 summary

Many high-spec PCs and servers released in recent years have announced products that support 10 Gbps connections. If you want to take advantage of products like these, CAT6A is the way to go. However, since many PCs for everyday use support 1 Gbps connection, CAT6 is recommended for these.

 I think that CAT6A is better considering only the bandwidth, but by grasping the performance of each and selecting the most suitable LAN cable according to the environment to be used, you can use the line comfortably.

The gender of RF connector

As with the majority of connectors, adapters, and plugs/sockets, RF connectors can also be classified by gender. Both male and female RF connectors are available, so it is important to choose the right type for your application.

Female RF connectors are the type which features the pin, also referred to as the plug. Conversely, an RF connector male type features a hole where the pin on female connectors can be attached to join two separate components together. Male RF connectors are also known as jacks.

This may sound a little confusing, as plugs are usually male and jacks are typically female. However, with RF connectors, it should also be noted that the male housing normally sits inside the female housing when the two are attached, hence the designated genders.

As an example, this N type connector has a pin so therefore, it is a plug. However, the mating half (this connector, for instance) fits inside so it would usually be considered the female. This leaves you with a female plug and a male jack or socket.

Introduction of N-type connector

An N-type connector is a type of RF connector that can handle high voltage and high frequency. Used to connect coaxial cables.

 The N-type connector was one of the first connectors to transmit high-frequency signals, and was invented by Paul Neill of Nokia Bell Labs in the 1940s. Since the characteristic impedance of the junction is matched and the frequency characteristics are excellent, it is mainly used for signal transmission in the UHF band (Ultra-High Frequency: 300MHz-3000MHz).

 Initially, N-type connectors were designed to transmit electrical signals up to 1GHz for military use, but today they can transmit up to 11GHz. In addition, the N-type connector recently designed by Hewlett-Packard's Julius Botka is capable of transmitting electrical signals up to 18 GHz and has a corresponding electrical resistance of 75 ohms as standardized by the U.S. military. Etc. are widely used in the cable TV industry.

 A connector called a BNC connector (Baby-series N Connector), which is a miniaturized N-type connector, is also widely used.

How to choose the correct M series connector according to the usage scenario?

With the development of various industries, many different styles and series of connectors have appeared. Today we are going to explain the m series connector. There are many things we need to pay attention to about M series connectors. Do you know how to choose different M series connectors according to the usage scenarios? If you are not clear about this, you can follow my article to learn about related knowledge.

The first thing we want to talk about is the M12 connector. It is available in 3 pin, 4 pin, 5 pin, 6 pin, 8 pin and 12 pin. Due to its special material, it is especially suitable for harsh environments where washing and corrosion may occur. Because they usually have IP65, IP68 and IP69 ratings. The M12 design can also be used for fieldbus connections.

Circular M12 and M8 connectors are mainly used in industrial automation, and are known for connecting various devices for safety. The M8 connector is on the other hand dedicated to industrial sensors. The connector uses a waterproof 3-pin screw. As long as it is pre-assembled, even if it is submerged in water, it will remain watertight and extremely waterproof.

Common applications for pin M8 connectors include sensors, actuators, switches, PLCs, I/O boxes, etc., used in food and beverage processing, machine manufacturing, rubber and plastics, textile and printing machines, and valves in HVAC systems.

The metal single coaxial m8 connector shell of the high-voltage m8 connector is a copper chrome-plated structure. The pins and sockets are copper plated with gold. On the basis of the original imported products, many improvements have been made, so that the shielding and high-voltage performance of the product are very prominent. It is suitable for setting up an AC bridge between the blocked place in the circuit or between a single circuit, so that the current is unobstructed and the circuit completes the function of the appointment.

No matter in any scenario, the main advantages of using M12 and M8 connectors are as follows:

1. Time spent installing wiring systems and maintaining them. This reduces the set-up time and the need to use electricians or qualified technicians.

2. When we choose the right connector, we can naturally extend the life of the machine. In the same sense, it saves consumers' expenses.

In summary, this article has explained to you how to choose the application scenarios of M series connectors. I believe that everyone will have a deeper and deeper understanding of M connectors. I hope this article can be of greater reference value for readers. If you want to learn more about connectors, you can browse other articles on our blog, or continue to follow our updates.

What you need to know before buying a D-SUB connector

D-subminiature connector, also known as D-sub, is a connector named after its metal shell shaped like the letter D. This ubiquitous connector is widely used in many fields ranging from consumer products to satellite equipment.

The D-sub connector contains two or more rows of parallel terminals surrounded by a characteristic D-shaped metal shell. This metal shell not only provides support for the mechanical structure but also has the function of shielding electromagnetic interference. There are many ways to connect the system circuit and the terminal on the D-sub connector, including crimping, soldering cup, PCB soldering, PCB press-in type, and winding connection. Many times the connector is also equipped with a locking system to ensure that it can remain connected even under shock and vibration. Sometimes people tend to confuse D-sub connectors with micro-D connectors and SCSI accessory device connectors (representing products HD-50 and HD-68). In fact, these products and D-sub connectors are separate systems and have obvious differences. D-sub is sometimes called a "rectangular cabinet" connector. The related models that can be heard in the jargon are DB9, DB15, DB25, DB37, and DB50, and the number refers to the number of terminal cores of the connector.

The purpose of D-SUB

D-sub connectors can be used in a variety of electronic products. This type of connector is commonly found in communication port devices and plays a role in establishing connections between different products such as computers, printers, and power supply units. Among them, the DB9 connector is used in token ring networks and controller area networks (CAN). D-sub connectors are also widely used in computer video output, game controller ports, multi-frequency analog signals, and AES digital audio recording studios. Over time, the use of connectors has also changed with the advancement of technology. For example, early Apple computers used connectors to connect external floppy disks, and Carmendore’s Commodore Amiga computer used the connector to connect to the external floppy disk and also used it to connect to the video output. However, due to the size and cost of these connectors, D-sub connectors have already withdrawn from the consumer product stage. However, this type of connector is still active in the field of non-consumer products and continues to bring significant comprehensive utilization value to their end-users in terms of shape, size, density, and cost.

Related Products

Elecbee produces a wide range of D-sub connectors and their accessories. The standard and high-density D-subminiature connector series are of high quality and reliable, and there are as many as six types of packaging and multiple performance options to choose from, in order to achieve your most ideal cost-effective match. The terminals used in all Baoxi D-sub connectors are solid terminals precision machined to ensure their reliability, durability, and high strength.
