ZAMEL Etero radio switch, 1-channel, 1 piece, RWS-211 J/12 V/N

Wireless surface-mounted switch for controlling 1 or 2 consumers, outdoor installation IP56 (hose-proof), range up to 300 m outdoors. Control of garage doors, pumps, lamps etc. Bidirectional, coded and interference-proof transmission Keeloq®. The microprocessor controlled radio switch RWS-211D controls electrical devices such as heaters, ventilation systems, air conditioners, pumps, barriers, lighting and display devices via radio. The radio switches use a rolling Keeloq® coding from microchip technology USA. Each transmission between transmitter and receiver is dynamically re-encrypted, each hand-held transmitter having an individual identification code. This requires the greatest possible security for the user. The transmission frequency between transmitter and receiver is 433.92 MHz. Due to the low transmission power (<5 mW) on this frequency, no state approval of the radio switch is necessary.
