Capacitive Proximity Sensors
Capacitive proximity sensors are sensing devices designed to detect both metallic and nonmetallic targets. They use the dielectric principle of capacitance to establish a sensing field in the vicinity of the sensor surface that creates a detection zone. Capacitive proximity sensors do not require physical contact with the target itself. Datavision capacitive proximity sensors are useful in detecting a wide range of objects. They can detect lightweight or small objects that cannot be detected by mechanical limit switches.
