Features When proximity switch is close to some target object, it will send out control signal. It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. The Proximity Sensor Switch is used for testing parts such as size and speeding Test objects: metal, and non-metal such as plastic, glass, water, oil, etc. Can also be used in frequency counters, frequency pulse generator, liquid level control and processing procedures for the automatic convergence.
