C-Lin proximity switch is a displacement sensor with switch output capabilities, offering NPN, PNP, normally open, normally closed, and relay outputs. It can detect various transparent and opaque objects, such as metals (iron, steel, copper), plastic, glass, wood, water, paper, and magnets. This sensor can be connected to PLCs, servo controllers, inverters, counters, and controllers to achieve automatic signal input, making it widely used in industries such as machinery, textiles, light industry, paper manufacturing, printing, and packaging.
Based on usage requirements, the proximity switch is divided into the high-end C series and the standard series. The inductive proximity switch is specifically designed to detect metal objects (e.g., iron, steel, copper).
