Reflector Type Proximity Sensor, Italy

A proximity sensor is a device that can detect or sense the approach or presence of nearby objects and for this it does not need physical contact. There are different kinds of proximity sensors. Some of them are listed Inductive: This type of sensor is used to detect nearby metallic objects.

Capacitive Proximity Sensor Working Principle: Capacitive proximity sensors work by detecting changes in capacitance between the sensor and an object. Factors such as distance and the size of the object will affect the amount of capacitance. The sensor simply detects any changes in capacity generated between the two.
