What is proximity switch?

The proximity switch is also called the proximity switch, also known as the non-contact stroke switch. It is a non-touch detection device besides the stroke control and limit protection. It can be used to detect the size and speed of parts, as well as the automatic connection of frequency conversion counter, frequency conversion pulse generator, liquid level control and processing sequence. It is characterized by reliable operation, long service life, low power consumption, high precision of multiple positioning, high operating frequency and bad working environment.

Functional characteristics of proximity switches

Among all kinds of switches, there is a displacement sensor which has the ability to "perceive" the objects close to it. Using the sensitive characteristic of displacement sensor to close objects to achieve the purpose of switching on or off, this is the proximity switch. MICROSONAR series proximity switches

When an object moves close to the switch and is close to a certain distance, the displacement sensor will have "perception" and the switch will act. Generally, this distance is called "detection distance". But different proximity switches have different detection distances.

Sometimes the inspected object moves one by one to the nearest switch at a definite time distance, and then separates one by one, so it repeats continuously. Different proximity switches can respond differently to the detected target. This echo characteristic is called "echo frequency".
