Features

  • Features
  • Conforms to EN 300 220-3 (Radio) and EN 301 489-3 (EMC)
  • Versions available on 169.44375MHz and 169.40625MHz
  • 12.5 kHz channel spacing
  • Data rates up to 3kbps
  • Usable range over 10km
  • Fully screened
  • Low power requirements

Available for operation at 169.44375MHz or 169.40625MHz in Europe, the ENT1 and the ENR1 combine full screening with internal filtering to ensure EMC compliance by minimising spurious radiation and susceptibility. The modules suits one-to-one and multi-node wireless links in applications including automatic meter reading (AMR), car and building security, EPOS and inventory tracking and remote industrial process monitoring.
