• Mount the sensor to metal that is connected to earth safety
ground (system ground).
• Adjust photosensor gain
to
the minimum required sensitivity. This
will reduce both electrical and optical problems.
•
The
photosensor cable shield should be grounded at both ends.
Th
is will reduce the effects
of
electrical noise produced by
contactors, motors, and arc-welders.
•
Th
rough-beam and retroreflective photosensors should be used in
the light operate mode. This also
will reduce the effects
of
electrical noise.
• Diffuse reflective photosensors should be used in the dark
operate mode. This
will reduce the effects
of
electrical noise.
