Power Requirements

The Z-Sensor requires 10-28 Vdc and consumes 7.5 watts.

Environmental Specifications

The operating temperature range of the Z-Sensor is -30°C to +55°C; storage
temperature range is -40°C to +85°C.
The Z-Sensor will work at 100% humidity and is rated to MIL-STD-810E for wind
driven rain and dust.

RF Connector

The RF connector is a standard 50-ohm female TNC wired for connection via coaxial
cabling to a GPS antenna with integral LNA. The TNC connector shell is connected
to the Z-Sensor common ground. The TNC center pin provides +5 Vdc to power the
LNA (maximum 150 mA draw) and accepts 1227 and 1575 MHz RF input from the
antenna; the RF and DC signals share the same path.
