KD-1 Capacitance Switch
$ 139.00


bulletCan be placed behind nonmetallic materials (graphics, models, maps) up to 1/4" thick.


bulletNo moving parts.
The KD-1, Proximity Switch, is a small device which detects visitors at close range (under 3/8 inch). Based on the detection of capacitance rather than touch, the KD-1 can be mounted behind graphics and within exhibit material up to 3/8 inch thick. Measuring approximately 2 x 1 x 1/2 inch (5 x 2 x 1 centimeters), this small activator comes wired with a 7 foot cord and a modular plug for quick connection to Museum Technology products. It may be used in other applications as long as operating power of 12 to 24 volts dc is available. The output of the KD-1 is a NPN transistor which conducts to the common terminal (ground) when active. Maximum output load is 100mA at 30 volts DC
Technical Specifications:
Operating Range: 3/8 inch, including thickness of material behind which it is mounted
Output Type: Transistor NPN switch conducts to common when active
Output Rating: Capable of sinking 100 mA at 24 VDC max
Power: Requires 12 to 24 volts DC; 15 mA max
Indicator: Red LED on side lights when output is ON
Cable: Six foot 3 conductor cable attached. Power, common, and output wires.
