Robot Connector system, reliability is the prerequisite

In the past, when we talked about industrial robots, we started with the upstream core semiconductor devices to see how to use semiconductor devices to achieve high-precision and high-reliability industrial robots. The increase in industrial automation rate is closely related to the development of robotics technology. At present, the tasks that industrial robots need to complete are developing towards high-speed processing and precision processing, driving the demand for multi-functional, flexible and intelligent terminal tools. This involves the entire robot connection system, which must record and transmit numerous data points from the robot and its production environment as quickly as possible. The connection system not only requires fast data transmission, but its protection is also a prerequisite for the high reliability of the entire robot body.

Trouble-free data transmission for Sensor connections Sensor technology and its integration are always current topics in the field of robot design. For smooth integration of sensor systems into robotic systems, connection components must meet high requirements for data transmission efficiency. Thanks to the reliability and high speed of connectors in data transmission, robots can detect their environment through an increasing number of Sensors. Robot connections typically require protection class IP65/IP67, and M12-X coded or push-pull RJ45/ M12 Connector are often chosen as sensor interfaces. The traditional M12-X encoding and Rj45 Connector are relatively well-known and can be found in many industrial scenarios. Push-Pull M12 Connectors enable higher-density M12 connections on industrial equipment by simply plugging the Connector into a PCB socket thanks to its push-pull technology.

Push-pull technology reduces the risk of intermittent or loose connections. In terms of use, this push-pull technology improves reliability and comfort; in terms of transmission, Push-Pull M12 integrates the highly integrated signal transmission of the traditional M12 system, which can meet bandwidth requirements up to 10Gbps. Additionally, higher conductivity can be achieved by changing the connection material, for example by silvering the connections. All signals in a push-pull connection are electrically connected and can be used to transmit analog signals, digital signals, low-voltage signals and bus signals. Another requirement for interference-free data transmission from sensors is high shielding. Both M12-X coding and push-pull RJ45/M12 connections provide 360° EMC and mechanical protection.

In particular, optimized RJ45 with three-wire choke (no interference between PoE and signal) provides excellent signal integrity, prevents saturation and significantly reduces transmission errors.It should be added that the number of connection modules must be chosen according to the technical specifications of the robot sensor. There are many different modules suitable for different current ranges (4 A, 10 A, 16 A or 40 A). The efficient integration of these different modules significantly expands the use of sensors in robotic applications and enables trouble-free data transmission. High-density, full power coverage connector is a high-performance connector designed to transmit power, data and signals in the harshest conditions. Of course, it is designed to withstand the harshest working conditions of robots, such as vibration, dust, temperature stress and mechanical shock.

With the various current flexible modularization trends and hybrid transmission upgrades, heavy-duty transmission can not only solve the transmission of high power under harsh working conditions, but also be flexible enough. Hybrid transmission solves the space problem first. Using modular systems, heavy-duty connectors can combine various power, signal and data transmission technologies (RJ45, D-sub Connector, USB, Quint, fibre optic) to significantly reduce the connector size. The mere saving of size is not a great advantage. In a single connector, the high density of signal connections in a small space is a greater attraction. When the high-performance connector module is fully configured, its signal connections can have up to hundreds of pins, and the high density goes without saying.

The heavy-duty connection of the high-performance, high-density electric shock structure covers a wide range of electrical power of the entire robot system, and can easily handle current ranges from a few amps to hundreds of amps.

In addition, the adaptation of Heavy Duty Connector cannot be limited to one type of signal or data transmission, but connections such as signal, power, pneumatic, coaxial cable and Ethernet can be realized. Heavy-duty connections are popular for industrial robots that must operate in harsh working conditions. Surge protection in connections In addition to the extremely high requirements for transmission measurement, control and regulation of highly automated equipment,it is absolutely necessary to protect electronic components from overvoltage. Robot shutdowns due to overvoltage are commonplace in many manufacturing operations. To actively protect the various signals in a production system, the reference potential of the signal circuit must be determined and taken into account when selecting suitable protection devices. Therefore, it is still necessary to integrate overvoltage protection into the connector.The overvoltage protection module can optionally use multiple protection components such as gas discharge tubes, suppression diodes, and resistors. In the event of an overvoltage, the combination of these components can ensure the coordinated dissipation of disturbances. With additional overvoltage protection, the robot can significantly extend normal operating time. The costing is not difficult to calculate. Summary: When it comes to robot connections,we don`t have to worry too much about the high transmission rate and high bandwidth indicators that we think of. It is relatively easy to achieve these two points with the current connector level. How to achieve better connection effects in terms of connection protection, space saving, and high-density plugging and unplugging is even more difficult.

After all, protection is the prerequisite for achieving high reliability of the entire robot body.
