Proximity switch is a general term for non-contact sensor. Its types are: inductive, capacitive, and Hall type. The output signal of the inductive proximity switch explained this time is mainly: on or off switch signal (that is, if there is a metal object at any position within the suitable range from the sensor head of the proximity switch to the suitable range detected by the product, it will give A switch signal is output. When the object is not within the detection distance, the sensor switch signal is opposite to the action).
