What is a terminal block?

Terminal block is an accessory product used to realize electrical connection, which is divided into connector category in industry. With the improvement of industrial automation and more and more strict requirements for industrial control, the use of terminal blocks is increasing.

With the development of electronic industry, the range of use and types of terminals are increasing. In addition to PCB terminals, the most widely used are hardware terminals, nut terminals, spring terminals, etc.

It is an accessory product for electrical connection. The metal conductor is enclosed in an insulated plastic sheet and has holes at both ends for inserting wires.

For example, if you have two wires, sometimes you need to connect them, sometimes you need to disconnect them. At this point, you can use terminals to connect them, and you can disconnect them at any time without welding or twisting them.

Terminal block features:

The transmission coupling of optical process is realized by using the existing rail type junction box frame screw connection technology and adding a circuit composed of electronic components. The optical isolation terminal has control terminal signal loss, high switching frequency, and no mechanical contact jitter. , no wear switch, high insulation voltage, not afraid of vibration, not affected by position, long service life and other advantages, so it has been widely used in the field of automatic control.

The core of automatic control is that the control unit must be reliably isolated from sensors and actuators to avoid interference. The wukg2 photoelectric isolation terminal in Sanmenwan can perform this function well, and ensure that the field signal and electronic control equipment need low-voltage matching. It can also be used as the interface element between the process control peripheral equipment and the control, signal and regulator equipment, and is suitable for different voltage and power ranges.
