Omron E3G DATASHEET

Photoelectric switch with built-in amplifier (long distance) in plastic housing

E3G

Retroreflective Models

• Sensing Distance of 10 m, with polarized light to detect shiny objects.

• Operation stability monitored ba the stability indicator.

Distance-setting Models

• Distance setting models with a long 2 m sensing distance incorporate a teaching function.

• Set sensing area (zone setting) function allows detection of shiny objects with uneven surface.

Common Features

• Meets IEC IP67 requirements.

• M12 rotary connector, pre-wired or terminal block connection

Features

Retroreflective Models

Though the Size Is Compact, the Sensing Distance Is as Long as 10m.

Replace the conventional through-beam model with the retroreflective model for saving wiring and installation space.

Easy monitoring of Operation stability by means of stability indicator.

The stability indicator becomes darker due to dust on the lens or improper optical axis adjustment.

Distance-setting

General

Distance-setting Models with a Long 2-m Sensing Distance Incorporate a Teaching Function

Sensitivity adjustment without being influenced by background objects is possible by simply pressing a button. Useful for teaching without a sensing object.

Easy Optimum Sensing Distance Adjustments

Teaching with and without a sensing object ensures highly accurate detection without influence from the background.

Zone Setting Function

Effective for detecting glossy objects, which were difficult to detect with conventional sensors. (D-ON)

background (conveyer).

Sensing zone

Approx. ±10%

Since the Sensor can have a threshold value not only in front of the background but also beyond the background, it is possible to detect objects such as mirror-surface objects that do not return light from the object surface.

Application

Detection of large works Retroreflective model can make longdistance detection, saving wiring.

Detection of large corrugated cardboard Just by installing the sensor on one side, only the boxes to be detected shall be sensed.
