1This is an inductive proximity switch sensor with 5mm detection distance. 2When the object approaches the sensing area of the switch, the switch can quickly emit electrical commands without contact or pressure required, accurately reflecting the position of the moving object. 3The switch stays open, and closes when it detects object in detection distance. 4Quick response, high reliability, strong anti-interference capability. 5Widely used in automatic control system for detecting, positioning control, counting, automatic protection and more.
