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.
