Proximity switch Manufacturer in Coimbatore
Proximity Switch consists a sensor circuit and a driver circuit. The sensor circuit purpose is used to detect any near by objects. The sensor circuit sends an output High signal to the transistor based driver circuit when any object found near to the sensor circuit. The transistor based driver circuit may use NPN or PNP transistors and it depends on the application we use.
A proximity switch is one detecting the proximity (closeness) of some object. By definition, these switches are non-contact sensors, using magnetic, electric, or optical means to sense the proximity of objects.
