KH3 Series Transmitter Module

Data Guide

Revised 3/18/2015

Description

The KH3 Series is ideally suited for
volume use in OEM applications such
as remote control and command, and
keyless entry. Housed in a compact SMD
package, it combines a highly optimized
RF transmitter with an on-board encoder.
When paired with a matching KH3
Series receiver / decoder module, a
reliable wireless link is formed, capable of
transferring the status of 8 parallel inputs
over distances of up to 3,000 feet.

Ten address lines provide transmitter uniqueness. No external RF
components are required except an antenna, making integration
straightforward.
