Robot RJ45 connector action!

In the robot connection, we know that the high transmission rate, high bandwidth, these high indicators are not too much to worry about, the current connector level is relatively easy to achieve both. It is more difficult to achieve better connection effect on connection protection, space saving and high density plug-and-play. After all, protection is the premise of high reliability of the whole robot. Full electrical coverage of high-density heavy-duty connections as designed to transmit power, data and signals under the most demanding conditions, aimed at the nature of the most demanding robotic conditions, vibration, dust, temperature challenge, mechanical shock, etc. . With the current trend towards flexible modularity and the upgrading of hybrid transmission, heavy-duty connections can not only solve the problem of high-power transmission in severe conditions, but also be flexible enough. Hybrid transmission first solves the space problem, with the help of modular systems, heavy-duty connectors can be a variety of power, signal and data transmission technology together (RJ45, D-Sub, USB, Quint, fiber) , the size of the connection is greatly reduced. The size savings alone are not much of an advantage. In a single connector, the high density of the signal terminals is a larger attraction at a space-constrained size. If the overload connector module is fully configured, its signal terminals can be up to hundreds of pins, high density goes without saying. High-performance, high-density electric shock structure of the heavy-duty connection, the entire robot system of the electrical performance coverage range from a few amps to hundreds of amps can easily bear the current range. And the customization of heavy-duty connection can not be confined to a signal or data transmission, can achieve signal, power supply, pneumatic, coaxial cable and Ethernet, and so on. Heavy-duty connections are popular for industrial robots that need to work under harsh conditions.

In addition to the extremely high requirements for transmission, measurement and control of connected surge protection highly automated devices, protection of electronic components from overvoltage is an implicit requirement. Robot outages caused by overvoltage are common in many manufacturing plants. In order to actively protect the various signals in the production system, the reference potential of the signal circuit must be identified and taken into account when selecting the appropriate protective equipment, therefore, it is necessary to integrate surge protection into the connector. The Surge Protection Module has the option of using multiple protection elements such as gas-filled tube, transient-voltage-suppression diode and resistors, which are combined to ensure a coordinated export of disturbance variables in the event of overvoltage. With an additional surge protection, the robot can significantly increase its normal operating time, a cost that is not difficult to calculate.

Sensor-connected non-interference data transmission in the field of robot design, sensor technology and integration has been a hot topic. In order to integrate the sensor system and robot system, the connector must meet the high requirement of data transmission efficiency. Thanks to the reliable and high-speed data transmission of the connector, the robot can sense the environment with more and more sensors. Robot connection generally requires the protection level of IP65/IP67, generally select the M12 X coding or push-pull RJ45/M12 connector on the sensor interface. The traditional M12 X encoding and RJ45 are well known and are found in many industrial scenarios. Push-pull M12 connectors, with push-pull technology, can achieve higher density of M12 connections in industrial equipment, just insert the connector in the PCB socket. And push-pull technology brings a lower risk of intermittent connections or loose connections. In terms of deployment, this push-pull technology improves reliability and convenience; in terms of transmission, push-pull M12 integrates traditional M12 systems with high-integrity signal transmission, which can meet bandwidth requirements of up to 10gb/s. In addition, higher conductivity can be achieved by changing the terminal material, for example by silvering the terminals. All signals in push-pull connection are electrocuted and can be used to transmit analog, digital, low voltage and bus signals.

Another requirement for sensors to achieve interference-free data transmission is high shielding. Whether it's an M12 x-encoded or push-pull RJ45/M12 connection, it has a 360 ° EMC and mechanical protection. In particular, the optimized RJ45, which uses a three-wire choke (no interference between the POE and the signal) , provides excellent Signal integrity, prevents saturation, and greatly reduces transmission errors. In addition, the number of connector modules should be selected according to the technical specifications of robot sensors. There are many different matching modules for 4A, 10A, 16A, or 40a for different current ranges. The efficient integration of these different modules greatly improves the use of sensors in robot applications and realizes non-interference data transmission. In the past, we talked about industrial robots from the point of view of the upstream core semiconductor device, how to achieve high-precision reliable industrial robots through semiconductor device. The improvement of industrial automation rate is closely related to the development of robot technology. At present, the trend that industrial robots need to process tasks is expanding to high-speed and precise processing, and driving the need for multi-functional, flexible, and smart end-of-pipe tools. This involves the entire robotic connection system, which collects and transmits a large number of data points from the robot and its manufacturing environment as quickly as possible. The connection system not only needs the fast data transmission, but also needs the protection to realize the high reliability of the whole robot body.
