● Distance display
• The greater the distance between the target and the sensor head,
the larger the displayed value becomes.
• If the target or background is out of the detectable range, is
displayed.
Note 1: The distance value indicates a reference value only. It is not
an absolute distance.
Note 2: If the target approaches the sensor head closer than the
specified range, the displayed value may increase.

transmitter up/down and right/left. Set the
transmitter at the midpoint of the range where
the green LED is lit. Secure the transmitter and
adjust the receiver position in the same way.
Turn the trimmer counterclockwise from Max.

position as Point A.
Set the trimmer midway between point A and
Max. Confirm sensor operation.
Mutual Interference
• The alternate-frequency type allows mutual interference suppression
up to two sensors.
• The alternate-frequency type is not available for the thrubeam type.
• To suppress the mutual interference with the thrubeam type or with
three or more sensors, contact KEYENCE.
Sensor Head Orientation
To detect a moving target, consider orientation of the sensor head
according to the direction of the movement.
