ARF 19/27 RX

RX module - 869.525MHz

TX/RX RF Modules

Highlights

  • ASK and FSK receivers for  ARF19 and ARF27 transmitters
  • Very low power consumption
  • Compliant with EN300-220 V2010

Description

These receivers enable an economic single-way digital link over a range of 6000m. They use the 868 MHz ISM band.

The applications covered range from radio remote control of gates, roller-blinds, point to point transmission, micro-networks … in general public or tertiary sectors of activity, home automation, access control, alarms… ; and more generally all low and medium rate data transmission applications where security depends on information redundancy.

These modules are compliant with the EN 300-220 V2010 standard.
