E3G
Retroreflective Models
• Sensing Distance of 10 m, with polar-
ized 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) func-
tion allows detection of shiny objects
with uneven surface.
Common Features
• Meets IEC IP67 requirements.
• M12 rotary connector, pre-wired or ter-
minal 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 ret-
roreflective model for saving wiring and installation space.

General
Distance-setting Models with a Long 2-m
Sensing Distance Incorporate a Teaching
Function
Sensitivity adjustment without being influenced by back-
ground objects is possible by simply pressing a button. Useful
for teaching without a sensing object.
Select either transistor (NPN/PNP select-
able) or relay output. Three connection
methods (plus a model with a timer func-
tion). Select either a DC power supply or a
variable power
supply: 24 V to 240 VAC or 12 to 240 VDC).

ments
Teaching with and without a sensing object ensures highly ac-
curate detection without influence from the background.

Teach with only the
background (conveyer).
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 long-
distance 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.
Detection of cars in multi-story parking lot
