KD-1 Internal Circuit External Circuit
Connecting KD-1 to External Device
KD-1 requires a supply voltage in the range of
12 to 30 volts DC. Current draw 15 mA (.015 Ampere)
The KD-1 will switch ON when a finger is held within
approximately 3/8 inch of the target. The KD-1 may
be mounted behind non-metallic material such as
Plex-glas or MDF. In general, this material should
be no thicker than 1/4 inch.
