Proximity switches are position switches that can operate without mechanical contact with the moving parts of the machine. When the moving object approaches the switch to a certain position, the switch sends a signal to reach the stroke control switch. It is usually used in industrial automation control systems to achieve detection and control. It is a non-contact and non-contact detection device.

There are many types of sensors. Commonly used ones include inductive and capacitive proximity switches that detect the presence or absence of metallic or non-metallic objects, ultrasonic proximity switches that can detect the presence or absence of reflected sound, and photoelectric sensors that can detect the presence or absence of objects. Proximity switches and non-mechanical magnetic switches that can detect magnetic objects, etc.
