Note: Due to the detection method, targets traveling horizontal to the sensor’s
optics are detected. Targets traveling vertically may not be accurately detected.
For reliable background suppression, a minimum separation distance of 6 mm
(0.24 in.) is recommended between the target and the backgrounds.
Sensor Alignment
The orange LED is an alignment aid which indicates that a margin of 2.5 has been
reached. This means that the sensor is receiving at least 2.5 times the signal strength
back from the target needed to trigger an output signal. In general, it is desirable to
have a higher margin to help overcome any deteriorating environmental conditions, i.e.,
dust build-up on the sensor’s lens. When aligning the sensor, the best performance can
be obtained if this margin indicator is illuminated with the target in place.
When aligning diffuse mode sensors, ensure that the sensitivity be set at its maximum
setting using the single-turn adjustment knob on the front panel. Pan the sensor left,
right, up, and down to center the beam on the target. It may then be necessary to
decrease this setting to prevent the sensor from detecting a background object. If this
problem persists, the application will require the use of a background suppression,
sharp cutoff diffuse, or retroreflective sensing mode.
