The EFS-AE4 hand-held transmitter is a compact and low-cost hand-held radio transmitter that is only available for the 433.92 MHz frequency band.

The code is usually set at the factory and is matched to the corresponding radio receiver. However, the code can be changed by the user at any time using the DIP switches.

At the same time, it is necessary to adapt the code on the radio receiver. This configuration can be done using the appropriate programming adapter. The required software is available for free.

The EFS-AE4 hand-held transmitter can be combined with most of our switching receivers (433 MHz). The functions are set on the radio receiver.

When a button is pressed, the hand-held radio transmitter simply transmits a code which the radio receiver uses to execute the relevant function.

Together with a compatible radio receiver, the user receives a flexible system that can be customised and expanded at any time to suit the requirements and the respective application.
