Hello everyone, here is a professional sharing from renhotec group. I'll share some basic knowledge about electronic components. I hope you can see that after you have a certain reference value, you will have a basic positioning in terms of purchase. Here are some basic introductions to the selection of wiring terminals for wires

1. Terminals are relatively better.

2. The advantages of the terminal block are that the wiring is convenient, simple, safe and stable.

3. Wiring terminal is a kind of accessory product used to realize electrical connection, which is divided into the category of connector in industry.

4. With the increasing degree of industrial automation and the increasingly strict and accurate requirements of industrial control, the consumption of wiring terminals is gradually increasing.

5. With the development of the electronic industry, more and more terminals are used, and there are more and more types. At present, in addition to PCB board terminals, there are hardware terminals, nut terminals, spring terminals and so on.

The wiring terminal is used to facilitate the connection of wires. In fact, it is a metal sheet sealed in insulating plastic. There are holes at both ends to insert wires, and screws are used to fasten or loosen. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time without welding or winding them together, Very convenient and fast. Moreover, it is suitable for the interconnection of a large number of wires. In the power industry, there are special terminal blocks and terminal boxes, all of which are wiring terminals, single-layer, double-layer, current, voltage, ordinary, breakable and so on. A certain crimping area is to ensure reliable contact and sufficient current.

Wiring terminals can be divided into wuk wiring terminal, European wiring terminal series, plug-in wiring terminal series, transformer wiring terminal, building wiring terminal, fence wiring terminal series, spring wiring terminal series, track wiring terminal series, through wall wiring terminal sub series, photoelectric coupling wiring terminal series, 110 terminal, 205 terminal, 250 terminal, 187 terminal and OD2 2 ring terminals, 2.5 ring terminals, 3.2 ring terminals, 4.2 ring terminals, 2 ring terminals, 6.4 ring terminals, 8.4 ring terminals, 11 ring terminals, 13 ring terminals, flag series terminals and sheath series, various ring terminals, tubular terminals, wiring terminals, copper strip and iron strip (2-03, 4-03, 4-04, 6-03, 6-04), etc.

6. Features

7. The transmission coupling of photoelectric process is realized by using the existing track terminal wuk connection technology and adding a circuit composed of electronic components.

8. The core of automatic control is that the control unit must be reliably separated from each sensor and actuator to avoid interference. Sanmenwan wukg2 optical isolation terminal can well complete this function 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 of process control and the control, signal and regulator device, and is suitable for different voltage and power ranges.

9. The optical isolation terminal has the advantages of low signal loss at the control end, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, no vibration, no position influence and long service life. Therefore, it is widely used in the field of automatic control.
