What Are The Methods Of Mutual Interference Prevention In Through-Beam Photoelectric Sensors?

For mutual interference prevention:

The light of the other sensor must not enter its own receiver.

Prevention methods are as follows.
  • Setting up out of parallel operating range
    Please confirm the parallel operating range from the catalog, install setting distance of adjacent sensor by 1.5 times min.
  • Alternate arrangement settings of photoelectric sensor
    Up to two sets of emitters and receivers can be attached closely as the following alternative arrangement shows.

    The light of the next emitter might be received when the sensing object is close to the photoelectric sensor.
  • Use of mutual interference prevention filter
    By use of mutual interference prevention filter, up to 2 sets can be attached closely.
    Mutual interference prevention filters are as follows.
    E39-E6 for E3S-A
    E39-E8 for E3S-B
    E39-E11 for E3Z-T[][]A
  • Mutual interference prevention by adjusting sensitivity
    When sensing distance is shorter than rating setting distance, the influence of mutual interference is nothing by lowering sensitivity volume though it depends on the customer applications and the selection models.
