Indicators
The following describes each ON/OFF condition of indicator when LIGHT-ON (L) is set.
When the DARK-ON (D) is set, the output indicator ON/OFF will reverse.
■
Mutual interference
• For reflective type / retro-reflective type sensors, mutual interference protection can be set for
up to 2 units. However, when the sensors are mounted facing each other, change the angle of
the sensor head to prevent light being emitted into each unit.(The mark detection type does not
include the mutual interference function.)
• Mutual interference prevention can be set when mounting a polarizing filter attachment
(optional with thrubeam type sensors) (If operation is unstable even after mounting the
polarizing filter, slightly lower the sensitivity.)
• For more detailed information about mutual interference or attachment, see the PZ-G Series
catalog or contact your nearest KEYENCE office.
*1 The detection distance is measured with the maximum sensitivity.
*2 The cable for the connector type / pigtail quick disconnect type is sold separately. The reflector for the retro-reflective type is sold separately.
KEYENCE products are strictly factory-inspected. However, in the event of a failure, contact your
nearest KEYENCE office with details of the failure.
1. WARRANTY PERIOD
The warranty period shall be for one year from the date that the product has been delivered to
