LJA8 Long Cylindrical Inductive Proximity Switch
LJA8 proximity switch is a displacement sensor with switching output. The output includes NPN, PNP, normally open, normally closed, relay, etc. It can detect transparent and opaque objects such as metal (such as iron, steel, copper), plastic, glass, wood, water, paper, magnets, etc. It can be controlled with PLC and servo Inverters, frequency converters, counters, and controllers are connected to realize automatic signal input.
Widely used in machinery, textile, light industry, papermaking, printing, packaging and other industries.At the same time, it is divided into two series: C series high-end proximity switch and ordinary type according to the use requirements.Inductive proximity switches detect metal objects (such as iron, steel, copper, etc.);If you have any questions, please feel free to contact us:بريد إلكتروني: [email protected]
