The NRX1 is a
VHF radio data receiver and it offers a low power, reliable
data link in a Radiometrix SIL standard pin out and foot print.
It is an enhanced, low cost version of the Radiometrix
RX1, but in a slightly larger dimension.
NRX1 is compatible with the TX1 series
of transmitters, and the BiM1 transceiver.

NRX1 is a VHF equivalent of Radiometrix
UHF NRX2 receiver and it is available for licence-exempt
operation in the UK 173MHz bands and European 169MHz band.
It is also available in the Australian frequency of 151.300MHz.
NRX1 modules combine effective screening with internal filtering
to minimise spurious radiation and susceptibility thereby
ensuring EMC compliance. They are particularly suitable
for one-to-one and multi-node wireless links where longer
ranges are required at low to moderate data rates. Applications
include building security, EPOS and inventory tracking,
remote industrial process monitoring and data networks.
Because of their small size and low power consumption, these
modules are ideal for use in battery-powered portable applications
such as handheld terminals.
