NiM2-xxx.xxx-10

UH F N a r r o w Ba n d Tr a n s c e ive r

The narrow band NiM2 transceiver

offers a low power, reliable data link

in a Radiometrix transceiver standard

pin out and footprint. This makes the

NiM2 ideally suited to those low power

applications where existing single

frequency wideband UHF modules

have insufficient range.

Features

Figure 1: NiM2-434.650-10

•

Conforms to ETSI EN 300 220-3 (radio) and EN 301 489-3 (EMC)

Standard frequency: 434.65 and 434.075MHz

Custom frequencies available in 433MHz (EU) band

Data rates up to 10kbps

Usable range over 500m

25kHz Channel spacing

Longer range compared to Wide Band FM modules

Available for licence-exempt operation in the 433MHz EU band, the NiM2 modules combine effective

screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring

EMC compliance. They can be used in existing low data rate (<10kbps) applications where the

operating range of the system using wide band transceivers need to be extended. Because of their small

size and low power consumption, NiM2 is ideal for use in battery-powered portable applications.

NiM2 is also available as separate NiM2T transmitter and NiM2R receiver, which can be used as dual-

in-line equivalents of NTX2 transmitter and NRX2 receiver respectively.

Applications

•

EPOS equipment, barcode scanners

Data loggers

Industrial telemetry and telecommand

In-building environmental monitoring and control

High-end security and fire alarms

DGPS systems

Vehicle data up/download
