C.T.C.S.S.

NC101 C.T.C.S.S. Encoder

The Model NC101 is the smallest C.T.C.S.S. Encoder on the market today, through the use of thick film hybrid technology. Micro-miniature in design allows for installation in very confined areas. The NC101 is completely field tunable to any of the C.T.C.S.S. tone frequencies (67Hz - 254Hz) without changing components or using frequency determining elements.

FEATURES:
Size: 0.64"W x 0.82"L x 0.20"H

Double sided adhesive mount - no need for mounting hardware
Easy interfacing to most systems
Immunity to RF
Low current drain
12" colored flying leads
Field tunable from 67Hz to 254Hz
Adjustable encoder output level
Operating voltage 5VDC to 15VDC

Size: .625"W x 0.80"L x 0.170"H

Double sided adhesive mount - no need for mounting hardware
Easy interfacing to most systems
Field programmable via solder bridging of numbered pads
Low current drain
Immunity to RF
12" colored flying leads
Field selectable from 67Hz to 250Hz
Operating voltage 7.5VDC to 24VDC
Reverse polarity protection
Voltage regulated circuitry
