Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Do not use the product in atmospheres or environments that exceed

product ratings.

● 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.

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)

Install the photoelectric sensor as shown in the following diagram.

● 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.
