Metal Connectors
• Always turn OFF the power supply to the Sensor before
connecting or disconnecting the metal connector.
• Hold the connector cover to connect or disconnect it.
• Secure the connector cover by hand. Do not use pliers, oth-
erwise the connector may be damaged.
• Use a tightening torque of 0.3 to 0.4 N·m for M8 connectors
and 0.4 to 0.5 N·m for M12 connectors. Vibration may
cause the connectors to become loose and reduce the de-
gree or protection is the tightening torque is not sufficient.
Mounting Direction for Distance-settable Models
• Make sure that the sensing
side of the Sensor is parallel
with the surface of the sensing
objects. Normally, do not in-
cline the Sensor towards the
sensing object.
If the sensing object has a glossy
surface, however, incline the
Sensor by 5
°
to 10
°
as shown in
the illustration, provided that the
Sensor is not influenced by
background objects.
• If there is a mirror-like object below the Sensor, the Sensor
may not operate stably. Therefore, incline the Sensor or
separate the Sensor from the mirror-like object as shown
below.
• Do not install the Sensor in the wrong direction. Refer to the
following illustration.
Install the Sensor as shown in the following illustration if each
sensing object greatly differs in color or material.

Indicator Operation
Note: If the stability indicator is lit, the detection/no detection status is stable
within the rated ambient operating temperature (
−
10 to 55
°
C).
Inspection and Maintenance
Cleaning
Never use paint thinners or other organic solvents to clean the
surface of the product.
