The light source switch and reflective plate can be moved horizontally and vertically to set them in the center of the illumination
area of the red incident light indicator lamp, allowing the operator to check whether the green stability indicator lamp is illuminated.

Turn sensitivity control from minimum to

light stabilizes.

If the object is larger than the lens diameter, set
the sensitivity control to the maximum setting. If
the object is the same size or smaller, turn the
sensitivity control from minimum to maximum
and set at point where incoming light stabilizes.

Precautions

Correct Use

Design

Fuzzy mutual interference prevention

• If the light source switches for the reflective plates are ar­ranged in a row, light from a neighboring light source switch
may be received, causing erroneous light reception signals
and errors.

• The fuzzy reciprocal interference prevention function moni­tors interference light for a certain period of time before illu­mination, and gathers data on the strength of the
interference light and the frequency of incidence. It then de­termines the risk of error due to these two factors using
fuzzy logic and controls the timing of illumination to reduce
the risk.

(When risk is low)

• Light is emitted after interfering light is gone.

Emission
pattern

(In case of high risk)

• Light is emitted after shifting to a gap
of interfering light.

Installation

Sensor installation

• When installing a photoelectric switch, avoid tapping with a
hammer. This may damage the water resistance function.

• Use an M4 screw, tightened to a torque of no more than

1.18 Nm.

(When using the mounting bracket)

• To set the sensor on the mechanical axis, use the optical
axis locking holes.

• When it is not possible to mount on the mechanical shift,
move the photoelectric switch vertically or horizontally so
that it is located in the center of the area illuminated by the
incident light indicator lamp. Verify that the stability indicator
lamp is on.

(Direct installation)
Install the photoelectric switch as shown in the following dia­gram.

Bottles

In some cases, factors such as the shape of a bottle prevent
stable detection. Please confirm that a correct detection is
performed before use.

Wiring Considerations

Cable

• An oil resistant cable is used to ensure oil resistance. Avoid
repeated bending of the cable.

• The bending radius should be 25 mm or more.

Avoiding Malfunctions

When using a photoelectric switch with an inverter or sub-mo­tor, be sure to connect FG (frame ground pin) and G (ground
pin). If not connected, errors may result.

● For adjustment

Light axis adjustment

Adjust the optical axis of the clamp to the direction of detec­tion object approach. The optical axis of the photoelectric
switch is the same as the mounting axis of the clamp, en­abling easy adjustment.

Optical axis locking hole

By fitting screws into the optical axis locking holes, the mount­ing bracket is set onto the mounting shaft of the mounting
bracket.
