Inductive Proximity Switch - Mechanical switches replaced by electronic switches.

Inductive Proximity Switch

The inductive proximity sensor was created to replace mechanical switches.Mechanical switches have the disadvantage, when you compare them to inductive sensors, that they make physical contact with the object that they need to detected. This often leads to damage of the mechanical switch.

Inductive switches have the capacity to detect metal objects, without actually touching them. So in pricipal these sensors are maintenance, and wear free. When your application allows it, you can opt to use a bigger sensor, so you get a larger switching distance. The switching distance is related to the size of the sensor, the bigger the sensor, the larger the switching distance.

If you need to replace mechanical switches in a project, you will need to use 2-wire inductive sensors. When you create a new machine, you can directly use 3-wire proximity switches. Or you could also opt to use 2-wire explosion-proof switches, even for a standard application, then you have the advantage that you can guard your switches on wire-break and defect.
