TXE-315-KH2 TXE-418-KH2 TXE-433-KH2 WIRELESS MADE SIMPLE KH2 SERIES TRANSMITTER / ENCODER DATA GUIDE DESCRIPTION The KH2 Series is ideally suited for volume use 1.220 in OEM applications such as remote control and command, and keyless entry. Housed in a compact SMD package, it combines a highly- RF TRANSMITTER/ENCODER optimized RF transmitter with an on-board 0.630 TXE-418-KH2 encoder. When paired with a matching KH2 LOT 10000 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 tri-state address lines 10 provide 59,049 (3 ) addresses for security and 0.180 uniqueness. No external RF components are required except an antenna, making integration Figure 1: Package Dimensions straightforward.
