The following symbols are used in this section.
Pin assignment
Only the thru-beam receiver incorporates the output.
NPN output type
Only the thru-beam receiver incorporates the output.
PNP output type
Only the thru-beam receiver incorporates the output.
Mount the sensor with a tightening torque of 0.5N·m or less.
Thru-beam type sensor
1
Set the operation mode switch to the Light-ON mode position (L side).
2
Placing the emitter and the receiver face to face along a straight line.
Move the emitter up, down, left and right to determine where light is
received with the help of the receiver’s operation indicator (orange). Set
the emitter in the middle of this area.
3
Adjust the angle of the emitter by twisting it up, down, left and right.
4
In a similar manner, adjust the angle of the receiver.
5
Check that the stability indicator (green) lights up.
6
Choose the desired operation mode, Light-ON or Dark-ON, with the
operation mode switch.
Retroreflective type sensor
Make sure to mount the sensor and the reflector at least 0.1mm
apart.
1
Set the operation mode switch to the Light-ON mode position (L side).
2
Placing the sensor and the reflector face to face along a straight line.
Move the reflector up, down, left and right to determine where light is
received the help of the operation indicator (orange). Set the reflector in
the middle of this area.
3
Adjust the angle of the reflector by twisting it up, down, left and right.
4
In a similar manner, adjust the angle of the sensor.
5
Check that the stability indicator (green) lights up.
6
Choose the deisred operation mode, Light-ON or Dark-ON, with the
operation mode switch.
