Application

Narrow pin interval detection

Stable detection of 5mm gaps that are not detectable by previous regression reflection models.

Wide detection range. Stable detection even at long distances.

Use of hyper-point LED as light source (1/2 light emission diameter of previous models) enables stable long-distance detection.

Stable detection of ampules and other small containers.

Visible spotlight for easy adjustment.

Features

We significantly increased the S/N ratio to enable a stable detection of PET bottles and various other transparent containers

Clear glass sensor E3S-CR62/67
Adoption of the coaxial retroreflective model

Stable detection can be carried out also to the transparent bottle of various form and surface states.
A state without a transparent bottle

Light is certainly intercepted by the transparent bottle.

Connectors (Sensor I/O connectors)

1. Output transistor switching is possible by means of NPN/PNP output switch.
2. Operation mode can be switched using L ON/D ON switch.

Operation

Sensitivity adjustment

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.

Sensing object	Detection state	Sensitivity adjuster	Indicator state	Adjustment procedure
Transparent pin or glass plate	Without sensing object	Min Max	ON Stability indicator (green) Light indicator (red)	Turn sensitivity control from minimum to maximum and set at point where incoming light stabilizes.
Opaque object	Object detected, object not detected	Min Max	ON Stability indicator (green) Light indicator (red)	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.

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.

(In case of high risk)

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

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 25mm 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.

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.

Tighten M4 screw

Tighten M3 screw

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.
