proximity switch
This makes the proximity switch an essential component in modern automation systems, providing a reliable and non-contact means of detecting an object. Imagine a proximal switch as the sensor passing between two gates: if it is within 100 meters of our signal box then the nearest side will be picked up by one contact, while that far from station yields another one invariable response. Technological features of the proximity switch include its ability to operate under harsh conditions, resistance towards dust and water, fast response time, and compatibility with many types of sensors. Proximity switches come in various forms (inductive, capacitive, monolithic) to serve a wide spectrum of applications from industrial automation and security systems to simple emergency stop light barriers. They are designed to improve safety, precision and production efficiency in machinery and processes which makes them indispensable for many industries.
