About Capacitive Proximity Sensors

Capacitive proximity sensors use the face or surface of the sensor as one plate of a capacitor, and the surface of a conductive or dielectric target object as the other. The capacitance varies inversely with the distance between capacitor plates in this arrangement, and a certain value can be set to trigger target detection.

Products & Services Related to Capacitive Proximity Sensors

Eddy Current Proximity Sensors

Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil.

Hall Effect Proximity Sensors

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.

Inductive Proximity Sensors

Inductive proximity sensors detect the presence or absence of an object using a critical distance.

Photoelectric Sensors

Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.

Ultrasonic Proximity Sensors

Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component.
