Thru-beam type sensor

1

For EX-23(-PN), 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

For EX-23(-PN), choose the desired operation mode, Light-ON or Dark-
ON, with the operation mode switch.

Retroreflective type sensor

1

Turn the sensitivity adjuster fully clockwise to the maximum sensitivity
position (MAX).

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.

When setting up the EX-29

(-PN) sensor, observe the following when

detecting glossy materials.

Make “L” shown in the diagram sufficiently long.

Install at an angle of 10 to 30 degrees to the sensing object.

Mount using M3 screws. For the front sensing type sensor, use M3 pan
head screws without washers.

The tightening torque should be 0.5N·m or less.

Mounting brackets

Optional sensor mounting brackets are available.

The tightening torque should be 0.5N·m or less.
