Photoelectric Sensors Mini Limit Switch Series Programming Static Operating Mode DIP Switch Settings S1 The weak signal indicator (red LED) will flash and the weak signal output will turn ON as the target enters the sensing range. When the target is fully within the sensing range, the weak signal output will turn OFF and the red LED will stop flashing.

Photoelectric Sensors Photoelectric M1K Series Mini Limit Switch Style Mini Limit Switch Series Programming output and the red LED will stay OFF. If the light received doesn't exceed the maximum level, perhaps due to a dirty lens, or doesn't fall below the minimum level, perhaps due to a background reflection, then the red LED will flash and the weak signal output will turn ON. This condition will continue until the normal light levels are received again by the sensor for one full cycle.
