Radio motors for roller shutters, awnings and external venetian blinds in Europe usually work with 433 MHz or 868 MHz. Transmitter and motor must use the same frequency and the same radio protocol.
Differences
- 433 MHz: widespread, often with simple hand transmitters
- 868 MHz: common in systems with feedback and group control
- Protocols are manufacturer-specific – the same frequency does not automatically mean compatibility
Examples at A-OK
- AM45 radio: 868 MHz (433 MHz on request)
- AM35 and AM45E: 433 MHz
- AM55: 868 MHz

Frequently asked questions
Will my old transmitter work with a new motor?
Usually not, as the protocols are manufacturer-specific. A new transmitter is paired.
