XT Capacitive Proximity Sensors

Telemecanique XT Capacitive Proximity Sensors provide non-contact sensing of any material up to 20mm, regardless of material or conductivity. These devices sense detection targets due to that target's ability to be electrically charged. Capacitive proximity sensors apply voltage to an area and detect objects by measuring the changes in capacitance, which is the ability of something to hold an electric charge. Since even non-conductors can hold charges, meaning about any object can be detected with this type of sensor.
