MINI-BEAM
Proper operation of these sensors requires that they be mounted securely and aligned
properly. For best results, final-mount these sensors in an 18 mm hole by their threaded
barrel or use one of the available mounting brackets, (see pages 6 - 7).

approximate position where it will be mounted. An object at the sensing
position should pass through the “core” of the sensor’s light beam.
maximum (clockwise end of rotation). If the sensor is “seeing” the reflected
light beam, the alignment LED should be “on”. Move the sensor up-down-
right-left to obtain the fastest receiver LED pulse rate. (alternatively, the retro
target may be moved.) If a pulse is not observable (too fast to count), reduce
the GAIN control (counterclockwise rotation) to obtain a countable pulse rate.
(As an aid to alignment, it may be necessary to further reduce the strength of
the light signal by tape-masking a portion of the retroreflective target area.)
found the sensor orientation that produces the fastest pulse rate, mount the
sensor (or reflector) solidly in that position. Increase the receiver GAIN to
maximum. Test the system by placing the object to be detected into the
sensing position. The indicator should go “off”. If an “LV” model sensor’s
indicator does not go “off” at this point, the sensor is reacting to light reflected
from the object (“proxing”).
If proxing occurs, reduce the GAIN setting until the alignment indicator goes
“off”, plus two additional full turns. Remove the object from the sensing
position and check that the alignment indicator LED comes “on” and pulses at
a rate of at least two flashes per second. Confirm that the LED goes “off” when
the object is replaced.
Proxing can be avoided by mounting the sensor so that it’s light beam is not
perpendicular to any flat reflective surface on the object to be detected (an
angle of 10 to 15 degrees is usually sufficient). Also, at distances of a few feet
or more, using more than one reflector may increase sensing contrast between
object-present and object-absent.
