Capacitive proximity sensors use the variation of capacitance between the sensor and the object being detected. 89 Add to Cart Compare. They utilize the electrical property of capacitance and the change of capacitance based on a change in the electrical field around the active face of the sensor. Types of Proximity Sensors: Inductive Proximity Sensor. Capacitive Proximity Sensors are non-contact sensors that can detect metallic and non-metallic targets through changes in capacitance between the sensor and target material. Capacitive sensors apply voltage to an area and detect objects by measuring the changes in an electrical property called capacitance, which is the ability of something to hold an electric charge. Capacitive proximity sensor are not so accurate compare to inductive sensor type. SICK’s capacitive proximity sensors feature extremely high electromagnetic compatibility (EMC), which prevents false switches and sensor failure. Mouser offers inventory, pricing, & datasheets for Capacitive Proximity Sensors. Capacitive Proximity Sensor The capacitive proximity sensors can detect both metallic and non-metallic targets in powder, granulate, liquid, and solid form. Ultrasonic Proximity Sensor Thus, if we discuss about different types of targets such as plastic target, metal target, and so on requires different types of proximity sensors such as capacitive proximity sensor or photoelectric proximity sensor, inductive proximity sensor, magnetic proximity sensor and so on.
