Question: 1 / 590

What do capacitance proximity detectors primarily detect?

Vibrations in the environment

Presence of human movement

Touching of metal objects

Capacitance proximity detectors primarily detect the touching of metal objects. This type of sensor operates based on changes in capacitance that occur when a conductive object comes close to it. When a metal object approaches the sensor, the capacitance changes, allowing the detector to sense its presence.

This technology is commonly used in applications where a non-contact method of detection is advantageous, such as in touch-sensitive controls or equipment that requires the ability to interact with metal without direct contact. The primary function of these detectors is to respond to the presence of conductive materials, making them particularly effective for detecting the proximity of metal.
