SENSOR PROXIMITY RECT.

Proximity switches or sensors measure "closeness" to a targeted object and open or close an electrical circuit when they make contact with or come within a certain distance of an object. There are four basic types of proximity switches: infrared, acoustic, capacitive, and inductive.

Sensors are used to perform a variety of detection functions for monitoring and controlling temperature, humidity, pressure, and other operating conditions such as voltage, amperage, viscosity, flow, motion, light, the level of liquids or product, vibration, force, speed, proximity and more.
