The handheld transmitters in the EFS-ETx series are compact, reliable and cost-effective radio hand transmitters for the 433.92 MHz frequency band. The code is usually set at the factory and is matched to the respective radio receiver. Due to the integrated DIP switch, the radio code can be changed by the user at any time. At the same time, a code adjustment on the radio receiver is necessary. This can be done using a suitable programming adapter. The required software is available free of charge.
The handheld transmitters EFS-ETx are compatible with most 433 MHz switching receivers from our range. The function settings are configured exclusively on the radio receiver. When a button is pressed, the handheld transmitter simply transmits a unique code – the corresponding response (e.g. pulse, key function, switching) is defined on the receiver. In combination with a suitable receiver, this creates a flexible and expandable radio system that can be individually adapted to the respective application.
