KD-3 Proximity Switch $ 169.00 Turns objects into touch switches Activates from inches away Works through wood, plastic Easy setup...self calibrating Normally open relay output

The KD-3 is a capacitive proximity switch employing analog and digital techniques to detect when a sensing plate, or wire, is approached. The KD-3 works with sensing plates of various sizes and shapes. The sensing plate must be metallic, such as aluminum, copper, or steel. The sensor plate size may range from less than a square inch to several hundred square inches. Often the object on display, if metallic, can serve as the sensing plate. Sensitivity may be set such that the switch activates when an approaching hand is still a number of inches away.
