Proximity Switch Wiring Guide (Part 2)

Many friends, after purchasing a proximity switch, will cause various problems because they do not know how to wire it, which may cause damage to the device. How to use and wire our proximity switch, let me briefly describe it for you.

The two-wire proximity switch is limited by the working conditions. When it is turned on, the switch itself produces a certain voltage drop, and when it is turned off, there is a certain residual current flowing through it. It should be considered when selecting. Although the three-wire proximity switch has one more wire, it is not troubled by unfavorable factors such as residual current, and its work is more reliable.

Some manufacturers lead the "normally open" and "normally closed" signals of the proximity switch at the same time, or add other functions. In this case, please follow the product manual for specific wiring.

The two-wire connection is directly connected in series in the circuit, just like an ordinary switch (that is, a contact), except that the contact is divided into positive and negative poles. The three wires are brown, blue and black. Normally, they are brown positive and blue negative. Black is the signal wire, which is connected to the load.

Between the black line and the blue line is the switch output, that is, a normally open or normally closed contact, which is directly connected in series to the loop.

Between the brown wire and the blue wire is an external power supply to drive this switch to work.
