PRELIMINARY INFORMATION

June 2012

The KD-3 is a capacitive proximity switch that uses a combination

of analog and digital techniques to detect a change of capaci-

tance on a remote sensing plate. The capacitance change is

brought about when the sensing plate is approached or touched.

Upon activation, a normally open relay closes, indicated by a red

LED lighting. Three modes are available: Pushbutton, in which

the relay stays closed for as long as presence is sensed; Pulse,

in which the relay closes for one second and then opens, or

Toggle, where the relay closes on the first touch, remaining

closed until a second touch occurs.

The KD-3 can work with sensing plates of various sizes and

shapes. The sensing plate needs to be of metal, such as copper

or aluminum, although others will also work.. In certain cases the

artifact itself may be used as the sensor, as in the case of a metal

teapot or bowl. In other cases, the sensor may be embedded in

the object, provided that the object is non-metallic. The KD-3 is

normally mounted close to the sensor, with a single wire connect-

ing the two. By use of coaxial cable, this distance may be

extended to several feet.

The sensor size and shape will, to some extent, determine the

distance over which the KD-3 will activate. Although not always

required, internal adjustments are available to optomize the sen-

sitivity and hence operating range. The KD-3 has been tested

with sensor plates as small as one-half inch square, and as large

as 12 by 16 inches.

The Auto-Calibration feature adjusts the KD-3 continuously to the

environment. Such things as dirt, humidity, ice or damage to the

sensor plate are automatically accounted for.
