SD-170E & SD-170EL Series Data Radios

The Maxon SD-170EL Series of data radios are durable, reliable and designed to meet the needs for a variety of wireless applications. These radios include optional FFSK or GMSK modem boards, which add even more diversity to this cost effective radio.

The modules incorporate the most requested mechanical footprint and BNC antenna connection. Adjustable transmit power settings from one to five watts provide the power needed on any job, and the tri-color LED indicator gives instant on-sight status of the radios operation. Combine those features with low current drain and fast transmitter/receiver attack times for a superior operation even in the harshest of system demands. The die cast aluminum cabinet/lid provides resistance to RF interference and gives exceptional environmental durability in extreme conditions.

Whether implementing a new system or installing into an existing system, the Maxon family of data telemetry radios have been the choice of OEM and end-users worldwide for over 35 years.
