Overview
MINI-BEAM2 is just one-third the size of the original MINI-BEAM. With its impressive
sensing performance and small size, the MINI-BEAM2 can mount inside machinery
where other self-contained photoelectric sensors will not fit or function.
Sensor configuration is extremely easy, using the MINI-BEAM2’s push button.
LED Indicators
MINI-BEAM2 has two bright LEDs; both are visible from the back, and each is visible
from one side of the sensor. They indicate the following:
Green ON steady: Power ON
Green 5 rapid flashes: Maximum gain
Green single flash: Push button “click” registered, gain reduced by one increment
Yellow ON steady: Light sensed
Yellow/Green alternating: Minimum gain (can not reduce further)
Sensor Configuration
Sensitivity Level
Sensitivity (gain) is adjusted easily using the sensor’s push button. Select from 8
possible setting increments.
1) Hold the push button until the Green LED flashes rapidly, 5 times, indicating that
the sensor is set to maximum gain.
2) To reduce gain, briefly press (“click”) the push button up to 7 times; gain will
reduce in single increments with each click. Yellow and Green LEDs alternate after
the lowest setting is reached.
3) To increase gain, hold the push button until gain increases to the maximum level,
then “click” the push button down to the appropriate level. Gain may be readjusted
in this way at any time. Green Power LED
