Proximity switch is a kind of displacement sensor with switch output, the output has NPN, PNP, normally open, normally closed and relay, etc. It can detect transparent and opaque objects such as metal (such as iron, steel, copper), plastic, glass, wood, water, paper, magnet, etc., and it can be connected with PLC, servo controller, frequency converter, counter, and controller to achieve the purpose of automatic input signals, which is widely used in the fields of machinery, textile, light industry, papermaking, printing, packaging and other industries. It is widely used in machinery, textile, light industry, paper making, printing, packaging and other industries. At the same time, according to the use of requirements, divided into C series of high-end proximity switches and ordinary type two series.
Hall type proximity switch detects the object as magnetic metal (e.g. magnet);
