Radio receivers for gate drives in the ultimate comparison
Sommer, Hörmann, Marantec, Crawford, GfA, MFZ & Normstahl – all radio receivers explained. Technology, comparison tables, buying advice & FAQs.
How radio receivers work
Radio receivers are the link between your handheld transmitter and the door control system. They receive the radio signal, check the code (rolling code, SOMloq2, BiSecur, bi-linked, etc.), and then transmit a switching impulse to the operator. This reliably opens or closes the door at the touch of a button.
Important differences in radio receivers
- Frequencies: The standard today is 868 MHz, older models operate at 433 MHz.
- Channels: 1–4 channels for residential users, multiple channels for industrial facilities.
- Protocols: SOMloq2 (Sommer), BiSecur (Hörmann), bi·linked (Marantec), Rollingcode (universal).
- Designs: plug-in receivers, board receivers, radio sockets.

Buying advice in 5 steps
- Check frequency: 868 MHz is standard, 433 MHz only for older systems.
- Observe protocol: only use compatible receivers/handheld transmitters.
- Select channels: 1–2 for garages, 4+ for industry.
- Design: socket, circuit board or module – depending on your needs.
- Accessories: Antennas for range, additional handheld transmitters.
Practical examples
- Private: Sommer SomPlug as a wireless socket for garden lighting.
- Commercial: Marantec Digital 343 for access gates.

FAQ – frequently asked questions about radio receivers
1) What does a radio receiver do?
It receives radio signals and transmits the switching impulse to the drive.
2) What frequencies are there?
Standard is 868 MHz, 433 MHz for older models.
3) How many channels do I need?
For private use, 1-2 are sufficient, for industry up to 4 or more.
4) What is a rolling code?
A changing code protects against copying.
5) Do old remote controls work with new receivers?
Only if frequency & protocol match.
6) Can I use multiple receivers?
Yes, e.g. for different gates or functions.
7) How do I install the socket receiver?
Simply plug it into the socket and program the handheld transmitter.
8) Do I need external antennas?
Only at long distances or in case of interference.
9) Industry vs. Private?
Industrial receivers are more robust and offer more channels.
10) How do I program handheld transmitters?
By teaching the receiver or controller.
