MINI-BEAM Installation and Alignment
Proper operation of the SM312CV or SM312CV2 sensor requires that it be mounted
securely and aligned properly. In some applications, excessive movement or
vibration can result in intermittent or false operation caused by loss of alignment.
For best results, final-mount the sensor in an 18mm-hole by its threaded barrel or
use a mounting bracket (see page 6).
Begin with the sensor at the approximate position where it will be mounted. With
power applied to the circuit and with the sensor set for “light operate”, direct the
sensor’s visible red spot at the object approximately 16 mm (0.65 in) (for model
SM312CV) or 43 mm (1.7 in) (for model SM312CV2) directly in front of the lens.
Move the sensor very slightly toward or away from the object while observing the
red LED indicator on the back of the sensor. Note the near and far points at which
sensing occurs (the range of distance over which the LED remains lit). Mount the
sensor at a point approximately midway in the range. This should correspond to the
point at which the red sensing spot on the object appears most sharply defined on
the object surface. Mount the sensor at this position and distance.

* Note regarding Light/Dark operate switch:
• Turn switch fully clockwise for light operate (sensor outputs conduct when
sensing light is received)
• Turn switch fully counterclockwise for dark operate (sensor outputs conduct
when sensing light is not received)
