What are the parameters of the M12 connector

图片
M12 connectors are circular connectors with a 12-mm locking thread used for sensors, actuators, Fieldbus and industrial Ethernet, primarily in factory automation applications. Often with ratings ofIP65, IP68 and IP69K, they are ideal for washdown and corrosive environments. ​ They are available with 3, 4, 5, 8 and 12 pins. While higher pin counts are not planned, other locking styles such as bayonet and push-pull are continuously under development. The M12 family can be found in many applications such as factory automation, measurement and control, communications, food and beverage, transportation, agriculture, robotics and alternative energy. When it comes to specific applications, users must select the right pin count. For sensors and power applications, 3 and 4 pins are required. Profinet and Ethernet use 4 and 8 pin counts. And Fieldbus, CANbus and DeviceNet primarily use 4 and 5 pin counts. Finally, specify 12 pins for signal requirements. Yeahui is a connector cable su

Hardwiring will be replaced by connector cable

图片
The Power Generation, Transmission and Distribution sector faces various challenges. Due to the large sums of data and signal transmissions required for monitoring all the equipment in the generation and distribution process, reliable connection is critical. Hardwiring does not always present itself as an efficient solution to such a challenge; industrial connectors by contrast not only can overcome the obstacles, but also propose an array of additional benefits. ​ Hardwiring is time-consuming, requiring high efforts and costs. Power networks are calling for short reaction times; the sub-systems need to run as safe and smoothly. In order to meet such requirements, it is useful to utilize industrial connectors. They not only reduce wiring costs, but also allow faster construction, commissioning and maintenance processes in the field. Traditionally, hardwiring has been seen a viable option for servicing the Power Generation, Transmission and Distribution sector. More recently, h

Driverless car drives his industrial chain

Wikipedia defines an autonomous car (also known as a driverless car, self-driving car, robotic car) as a “vehicle that is capable of sensing its environment and navigating without human input. Autonomous cars use a variety of techniques to detect their surroundings, such as radar, ladar (laser lights), GPS, the odometer and computerised vision. Truly autonomous cars do not require human intervention other than setting the destination and starting the system. The automatic system can drive and make its own decisions. ​ The automotive industry has become a very crowded place as automakers lost their position as the key players in the market. IT giants are moving in on this industry, promoting automation and domination of AI on the roads. The future highways and city streets are being looked at through the eyes of their intended future inhabitants: driverless cars and trucks. In May 2014, Google presented its new prototype of driverless cars without a steering wheel, gas pedal, or

what is the cause of the damage to the cable

图片
Cables are required for both life and work. Commonly there are car cables, electronic cables, terminal cables and connecting harnesses in various types of equipment. Problems with these cables can easily lead to the inability of the machine and equipment to function properly. In this case, the manufacturer considers this when designing the cable, so multiple tests are performed during the production process. So  what is the cause of the damage to the cable ? ​ 1. The reason for the natural damage of the  cable during use can be caused by the long time of use of the product. Each product has a certain life span, and nothing can be used for a lifetime without damage. 2. The mechanical properties of the cable are reduced, which is very likely to cause an open circuit and a short circuit between the wires. This will directly cause the cable to burn out, and the terminal of the product will be oxidized and deformed, which will result in The bad contact occurred, causing the device no

What to pay attention to when purchasing connectors

The cable is one of the types of electronic wire harnesses, and is widely used in various electronic devices, such as electric vehicles, household appliances, communication equipment, automation equipment, and the like, and different functions of the electronic harness connecting wires have different production standards, specific Including the specifications of the wire, the thickness of the terminal cable, the material of the wire harness, and so on. ​ Some informal manufacturers use recycled PVC for the insulation layer, recycled copper, copper clad aluminum, steel wire or several hybrids for the core conductor. These kinds of conductor resistance are very harmful to electronic equipment, so be careful when choosing. The regular cable insulation layer must be made of new anti-oxidation PVC plastic. The core conductor is made of oxygen-free copper, tin-plated copper or silver-plated copper made by air isolation. It must be processed by multiple processes and precise equipment.

​Cable is the Development needs of equipment

Safety performance is the core quality of common cable products. Because it is a connecting cable, it mainly transmits electrical energy and electrical signals. Generally, electrical appliances are good. Normal pressure operation is easy to grasp, and some high-voltage equipment and data transmission cables are used. The performance of the cable is required to be particularly high-end. ​ The connector is the main component of the device, because it is not the main body of the device, but if there is a problem, it will affect the operation of the entire device. There is a lot of pressure on manufacturers of production cables because today's connectors require considerable safety and stability, and the precision is increasing. Now  most of people are inseparable from the connection line. The data lines on the mobile phone are mostly used by most people. In many cases, if there is a problem with the data line, we only need to change one data line. We replaced the entire chargin

Carsharing pushes connector industry development

not always does the traditional public transportation meets all the passenger requirements. Some do not like the speed of the trip, some - the traveling conditions, some are confused by the large number of transits. In addition, often at the time of buying a ticket for public transport, all seats are booked, and to reach the destination at the right time without resorting to the services of private carriers was previously impossible.it was impossible before the advent of ride-sharing apps and services. Getting Ready for Efficient Car Sharing. ​ Carsharing is a special kind of car operation, in which those who use them may not actually own the used vehicles. That is, the car is rented by a few users either from the car park owners or from individuals. A specific vehicle is used when it is free. Thus, it allows saving on the acquisition of private transport while not denying yourself the benefits that are available to true car owners. Moreover, if spread wide enough, this practice w

The frequency of Coaxial cable

图片
Coaxial cable is the most commonly used transmission line for RF and microwave applications, because it provides reliable transmission with the benefits of wide bandwidth and low loss and high isolation. Major manufacturers of transmitting equipment, i.e. radio and TV, radar, GPS, emergency management systems, air and marine craft, use coaxial cables. The uses of coaxial cable apply to any system in which signal loss and attenuation must be minimized. Unlike waveguides, coaxial cable has no lower cutoff frequency but what about its upper frequency? ​ Frequency Like other parts of the electromagnetic spectrum, radio frequency (RF) is identified by its frequency in Hertz (Hz) or wavelength in meters. An inverse relationship exists between these two concepts such that as frequency increases, wavelength decreases, with the reverse being true as well. The strength of a radio frequency signal is measured in Watts. A frequency band refers to a designated section of the RF spectrum like

Fatal failure of the connector terminals

图片
In many cases, if the terminal fails, the connector will have many problems, such as leakage, short circuit, and so on. So what are the faults in the connector terminals? ​ Poor contact The metal conductor inside the terminal is the core part of the terminal. It transmits the current or signal from the outside to the corresponding contact of the connector to which it is matched. It is very important in the overall circuit, so the contact must have an excellent structure and good electrical  conductivity Due to the unreasonable design of the contact structure, the wrong selection of materials, the deviation of the processing dimensions, the instability of the mold, the harsh storage environment and improper operation, the contact parts may be in poor contact. Poor insulation The function of the insulator is to keep the contacts in the correct position and to insulate the different contacts from each other. Therefore, the insulator must have excellent insulation properties.

​what is a crimp-on connectors

图片
In short, the crimp connector is one of the electrical connectors that are crimped together with the crimping tool by a wire and connector. Crimped connectors are a type of solderless connection, using mechanical friction and uniform deformation to secure a connector to a pre-stripped wire (usually stranded). Crimping is used in splice connectors, crimped multipin plugs and sockets, and crimped coaxial connectors. Crimping usually requires a specialised crimping tool, but the connectors are quick and easy to install and are a common alternative to solder connections or insulation displacement connectors. Effective crimp connections deform the metal of the connector past its yield point so that the compressed wire causes tension in the surrounding connector, and these forces counter each other to create a high degree of static friction. Due to the elastic element in crimped connections, they are highly resistant to vibration and thermal shock. ​ Crimped contacts are permanent (i.

In our world of data, all connections are inseparable from connector. connector have occupied an indispensable position in this era, and many people have higher and higher requirements for connector. Let us talk about the function, structure and quality of connector. ​ Connector function connector used in different industries which have different functions, and the response differs in structure and product precision. For engineers designing connector, it is important not only to understand the requirements of the connector customer, but also to understand the application of connector as much as possible. Connector structure connector are usually made of plastic plus terminals. Some complex connector require the addition of other accessories or components. The most common components include iron shells, springs or shrapnel. Some complicated and high-precision connector have complicated production processes. So we will try to shorten the production process time when designing

What should I pay attention to when designing the connector

For almost all equipment, the ultimate goal of manufacturing is to make it easier to use, and for connector manufacturers, pay attention to the connector manufacturing process when designing connectors. What should I pay attention to when designing the connector? ​ 1. The connector is good or not, not determined by the power of the function, but by the ease of use of the connector, that is, the connector can be used while it can complete its own functions, which is the first principle to designing the connector . 2. Designing the connector requires familiarity with the environment in which the connector is used, and the taboos it uses. 3. The designed connector should have reasonable maintenance mode and reserve adjustment connector space, in order to facilitate the maintenance of the connector in the later stage. 4. When the connector is designed, the mechanical properties of the connector must meet the basic requirements. Yeahui is a connector supplier with 11 years of e

Gold plating on the connector will affect the service life

What is the use of automotive connectors

图片
What is the use of automotive connectors? If there is no automotive connector, what will the car industry look like? The automotive circuits are permanently connected together by continuous conductors. If the electronic device wants to be connected to the power supply, the two ends of the connecting wires must be fixed to the electronic device and the power supply by soldering, etc., but this way, It will bring a lot of inconvenience. ​ Taking a car battery as an example, assuming that the battery cable is fixedly soldered to the battery, the automobile manufacturer increases the workload for installing the battery, increasing the production time and cost. If the battery needs to be replaced, it needs to be stripped to remove the old one, and then soldered to the new one, which requires more labor costs. But with the car connector you can save a lot of trouble, just disconnect the connector, remove the old one, install a new battery, and reconnect the connector. What are the ben

How do we measure OBD II output

How do we measure OBD-II output? Pre-OBD-II cars had connectors in various positions under the dashboard and under the hood. All OBD-II cars have a connector located in the passenger compartment easily accessible from the driver's seat. Check under the dash or behind or near the ashtray. A cable is plugged into the OBD-II J1962 connector and connected to AutoTap or another scan tool. AutoTap is available in PC/laptop or a Palm PDA versions. Other scantools on the market range from simple hand-held meters that display trouble codes, up to a large console computer-based unit costing thousands of dollars. ​ What good does it do to measure OBD-II output? OBD-II signals are most often sought in response to a "Check Engine Light" appearing on the dashboard or driveability problems experienced with the vehicle. The data provided by OBD-II can often pinpoint the specific component that has malfunctioned, saving substantial time and cost compared to guess-and-replace repa
