Sensor Cable, Wire Colors and Functions
The AR100 sensor includes a hardwired cable (sensor cable) with solder
tail wires. Connection according to the instructions is essential for correct
sensor operation. Read the wire descriptions for connection information.
The table below shows the wiring on systems ordered without a power
supply.

Power Supply (Red, Brown)
The Brown wire is the Power Supply Common return, also named Ground.
It carries the return current for the power supply.
The Red wire is the Power Supply Input to the sensor. The sensor requires
+9 - 36 VDC power and consumes 1.5
–
2 Watts of power (< 250mA
draw) depending on the sensor’s configuration
.
Power supplies from 9 VDC to 36 VDC may be used. Higher voltages will
result in excessive current drawn by the over-voltage protection circuitry
and may cause permanent damage. Voltages less than 9 VDC may result
in inaccurate measurement readings or non-functionality.
