TXE-433/418/315 MHz - KH Series Transmitter Module with Encoder

4.25 TXE-433/418/315 MHz-KH series transmitter module with encoder TXE-433/418/315 MHz-KH series is a radio frequency encoding transmitter module, which contains a high-performance radio frequency transmitter chip and an encoder chip. It is used in combination with the KH series decoder receiver module to form a highly reliable wireless connection, capable of sending 1 to 8 parallel input states; the address code is 310 groups; the transmission distance exceeds 91.5 m (300 ft). The matching decoder receivers are RXD-315-KH (315 MHz), RXD-418-KH (418 MHz) and RXD-433-KH (433 MHz). The KH series radio frequency encoding transmitter is suitable for long-distance remote control, keyless entry system, garage door opening, lighting control system, fire safety alarm and industrial automation control systems. 

The main technical features are as follows: 

・No external RF components are required except the antenna; 

・Maximum output power is 4 dBm; 

・The transmission data length is 26 bits × 3; 

・Operating voltage is 2.7～5.2 V; 

・The operating current is 1.5 mA and the sleep mode current is 1 μA.
