How to use universal proximity switches safely
Proximity switches, as the name implies, change their state when approaching an object. This type of switch is generally used in mechanical motion. After two objects are close, the trigger switch gives a signal, and the control unit (PLC) detects this signal and takes the next action.


First of all, the universal proximity switch is a conductor. It uses the conductor to generate an eddy current when it approaches an object that can generate an electromagnetic field. This eddy current reacts to the proximity switch to identify whether there is a conductor approaching. That is, it plays a role of controlling current and protecting safety.
The universal proximity switch is often touched by us in life. As long as you carefully understand its classification and instructions before using it, and then accurately distinguish the positive and negative poles of the power supply, correctly install and connect it, you can use it correctly and safely.
We should know that general-purpose proximity switches are also divided into many types such as electrical proximity switches and photoelectric proximity switches. The most common thing in life is the electrical proximity switch. We need to connect brown or red to the positive pole of the power supply and blue to the negative pole of the power supply according to the color of the wire, and use it correctly and safely.
In this way, how we should safely use universal proximity switches is just a small question.
