A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.The object being sensed is often referred to as the proximity sensor's target. Create capacitive sensors that can detect touch or proximity. Tags: proximity sensors. Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. The main difference between the two, capacitive proximity sensor produces an electrostatic field instead of a magnetic field and the sensing area of the capacitive proximity sensor can be actuated by both conductive and non-conductive materials. Proximity Sensor - Capacitive. Add to Cart Compare. Capacitive type of proximity sensors can detect both metal and non-metallic objects by detecting any change in the capacitance between the sensing object and the sensor. A proximity sensor detects an object when the object approaches within the detection boundary of the sensor.
