True or False: Capacitive Proximity Sensors can detect both metallic and non-metallic materials.

Capacitive proximity sensors are designed to detect changes in capacitance caused by the presence of nearby objects. These sensors can sense both metallic and non-metallic materials, making them versatile for a range of applications. The operation of capacitive sensors is based on the dielectric properties of the materials in proximity to the sensing area. When a dielectric material (which can include plastics, liquids, and other non-metallic substances) enters the sensing field, it alters the capacitance of the sensor.

This ability to detect diverse materials is what makes the answer true. Unlike inductive proximity sensors, which primarily detect metallic objects, capacitive sensors expand their capability to a broader range of materials, including liquids and granular substances. Therefore, the statement about capacitive proximity sensors detecting both metallic and non-metallic materials accurately describes their functionality.
