1、It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. 2、When proximity switch is close to some target object, it will send out control signal. 3、The Proximity Sensor Switch is used for testing parts such as size and speed 4、Can also be used in frequency counters, frequency pulse generator, liquid level control and processing procedures for the automatic convergence. 5、Test objects: metal, and non-metal such as plastic, glass, water, oil, etc. Features: It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. When proximity switch is close to some target object, it will send out control signal. The Proximity Sensor Switch is used for testing parts such as size and speed Can also be used in frequency counters, frequency pulse generator, liquid level control and processing procedures for the automatic convergence. Test objects: metal, and non-metal such as plastic, glass, water, oil, etc. The detection distance varies with the conductivity, dielectric constant, water absorption rate and volume of the tested body, and a large detection distance can be obtained for the grounded metal.
