Technical Explanation for Proximity Sensors - Omron

Proximity Sensors detect the physical changes of an object, so they are almost completely unaffected by the object's surface color. 7. Unlike switches, which rely on physical contact, Proximity Sensors are affected by ambient temperatures, surrounding objects, and other Sensors. Both Inductive and Capacitive Proximity Sensors are

Capacitive Proximity Sensors Theory of Operation - SoftNoze

Ultrasonic Proximity Sensors Theory of Operation Ultrasonic proximity sensors use a transducer to send and receive high frequency sound signals. When a target enters the beam the sound is reflected back to the switch, causing it to energize or deenergize the output circuit. Piezoelectric Disk A piezoelectric ceramic disk is mounted in the ...

General Inductive proximity sensors

Inductive proximity sensors enable the detection, without contact, of metal objects at distances of up to 60 mm. Their range of applications is very extensive and includes : the monitoring of machine parts (cams, mechanical stops, etc.), monitoring the flow of metal parts, counting, etc.

The Proximity detection feature provides distance mea-surement (E.g. mobile device screen to user’s ear) by pho-todiode detection of reflected IR energy (sourced by the in - tegrated LED). Detect/release events are interrupt driven, and occur whenever proximity result crosses upper and/ or lower threshold settings. The proximity engine features
