Features and Applications

The TXM-433-LR is a Part of LR Series is ideal for the wireless transfer of serial data, control, or command information in the favorable 260-470 MHz band. The receiver's advanced synthesized architecture achieves an outstanding typical sensitivity of -112dBm, which provides a 5-10 times improvement in range over previous solutions.

The transmitter's synthesized architecture minimizes the effects of antenna loading, providing a more stable, consistent performance. When paired, a reliable wireless link is formed, capable of transferring data at rates of up to 10,000bps over distances of up to 3000 feet
