SmartSensor Matrix User Guide
Keep these general guidelines in mind as you choose your sensor
mounting location:
˿
Make sure the sensor has a clear view of the area you want to
detect. Pay particular attention to signs, poles, signal heads,
and mast arms.
˿
The sensor needs to see at least 15–20 ft. (4.6–6.1 m) of a lane
in order to detect it properly.
˿
Vehicles should typically enter the sensor’s footprint on the
rounded edge.
˿
Make sure the footprint extends several feet beyond the stop bar.
˿
The front of the sensor should be at least 10 ft. (3 m) away from
suspended power lines and other electrical cables.
˿
Keep cable lengths in mind when you pick mounting locations;
when you use the Wavetronix 6-conductor cable, runs can be
as long as 1000 ft. (304.8 m) if you’re using 24 VDC and RS-485
communications; for longer connections, consider
alternate wired and wireless options.
The mounting location will vary based on your intersection and
your needs. The locations in the image below are recommended
because of their clear view of the detection area.
