RXD-315-KH2资料

MODULE DESCRIPTION
The KH2 Series transmitter / encoder module combines a high-performance Surface Acoustic Wave (SAW) based transmitter with an on-board encoder. When combined with a Linx KH2 Series receiver / decoder, a highly reliable RF link capable of transferring control or command data over line-of-sight distances of up to 3,000 feet is formed. The module accepts up to 8 parallel inputs, such as switches or contact closures, and provides ten tri-state address lines for security and creation of 59,049 (310) unique transmitter / receiver relationships. The KH’s compact surface-mount package integrates easily into existing designs and is friendly to hand production or automated assembly.

WIRELESS MADE SIMPLE ®
KH2 SERIES TRANSMITTER / ENCODER DATs 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 highlyoptimized RF transmitter with an on-board encoder. When paired with a matching KH2 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 provide 59,049 (310) addresses for security and uniqueness. No external RF components are required (except an antenna), making integration straightforward.
