● Designing
Fuzzy Mutual Interference Prevention Function
• If reflective Photoelectric Sensors are installed side by side, each
reflective Photoelectric Sensor may be influenced by the light
emitted from the other Photoelectric Sensors.
• The fuzzy mutual interference prevention function of the E3S-
CR62/67 enables the E3S-CR62/67 to monitor any light
interference for a certain period before the E3S-CR62/67 starts
emitting light so that the E3S-CR62/67 can retrieve the intensity
and frequency of the light interference as data.
Using this data, the E3S-CR62/67 estimates with fuzzy inference
the risk of the malfunctioning of the E3S-CR62/67 and controls the
timing of the E3S-CR62/67’s light emission.
When the risk is low:
• The E3S-CR62/67 waits until there is no light interference and
emits light.

When the risk is high:
• The E3S-CR62/67 emits light between each light interference
moment.

Bottles
In some cases, factors such as the shape of a bottle prevent stable
detection. Please confirm that detection takes place correctly before
use.
● Wiring
Cable
• The E3S-CR62/67 uses an oil-resistive cable to ensure oil
resistivity. Avoid repeated bending of the cable.
• Do not allow the cable to be bent to a radius of less than 25 mm.
Avoiding Malfunctions
When using a photoelectric sensor with an inverter or sub-motor, be
sure to connect FG (frame ground terminal) and G (ground terminal).
If not connected, errors may result.

● Mounting
Mounting the Sensor
• When mounting the E3S-CR62/67, do not hit the E3S-CR62/67
with a hammer, or the E3S-CR62/67 will loose watertightness.
• Use M4 screws to mount the E3S-CR62/67. The tightening torque
of each screw must be 1.18 N·m maximum.
(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 mounting)

● Adjusting
Optical axis adjustment
Adjust the optical axis of the clamp to the direction of sensing object
approach. The optical axis of the photoelectric sensor is the same as
the mounting axis of the clamp, enabling easy adjustment.
About the 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.
