It's better to use terminals.
The advantage of the terminal is that it makes the connection convenient, simple and safe.
Terminal is an accessory product used to realize electrical connection, which is divided into connectors in industry.
With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the use of terminals is gradually increasing.
With the development of the electronic industry, the use of terminals is more and more, and the types are more and more. At present, besides PCB board terminals, there are also hardware terminals, nut terminals, spring terminals and so on.
The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. There are screws for tightening or loosening, such as two wires. Sometimes they need to be connected and sometimes they need to be disconnected. At this time, they can be connected by terminals, and they can be disconnected at any time without having to disconnect them. It's easy and fast to weld or twist together. And suitable for a large number of wires interconnection, in the power industry there are special terminal row, terminal box, above all are wiring terminals, single-layer, double-layer, current, voltage, ordinary, breakable and so on. A certain area of crimping is used to ensure reliable contact and sufficient current.
Connection terminals can be divided into WUK terminal, European terminal series, plug-and-pull terminal series, transformer terminal, building wiring terminal, fence terminal series, spring terminal series, track terminal series, through-wall terminal series, photoelectric coupling terminal series, 110 terminal, 205 terminal series, 250 terminal, 187 terminal series. OD2.2 ring terminal, 2.5 ring terminal, 3.2 ring terminal, 4.2 ring terminal, 2 ring terminal, 6.4 ring terminal, 8.4 ring terminal, 11 ring terminal, 13 ring terminal flag terminal and sheath series, various ring terminal, tubular terminal, wiring terminal, copper band iron belt (2-03, 4-03, 4-04, 6-03, 6-04) and so on.
By using the existing track terminal WUK connection technology and the circuit composed of electronic components, the transmission coupling of photoelectric process is realized.
The core of automatic control is that the control unit must be reliably separated from sensors and actuators in order to avoid interference. The WUKG2 optical isolator terminal in Sanmenwan can accomplish this function well, and ensure that the field signal matches the low voltage required by the electronic control device. It can also be used as the interface element between the peripheral equipment and the control, signal and regulator devices in the process control. For different voltage and power ranges.
Optical isolation terminal has many advantages, such as low signal loss, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, no vibration, no position influence and long service life, so it is widely used in the field of automatic control.
