Marantec Digital 321 multi-bit 433 MHz 1 channel handheld transmitter

1 channel 433.920MHz rolling code

The handheld transmitter uses a rolling code method. This makes the coding highly secure. The radio signal varies according to a certain rule (algorithm). The transmitter range is approx. 35m and can even be operated from the car. In bad weather conditions such as rain or snow, the transmitter range can be affected. Steel, concrete, walls or trees can also limit the transmission range of a radio transmitter or garage door opener.

Please note that despite the same frequency, coding type and appearance, a radio remote control can have completely different technical characteristics. Basis are manufacturer and model. We point in our store of course to compatible,tested handheld transmitters and alternatives.
