Omron E3M-V DATASHEET
Mark Sensor
E3M-V
• Detects laminated or light-dispersing
objects in stable operation without being influenced by mirror reflection.
• Double indication of the detection level
and threshold level allows easy grasp
of the operating status and easy adjustment.
• Automatically sets to the optimum
threshold level while sensing objects
are being conveyed and incorporates
an auto-teaching function that discriminates between the mark and background and turns ON when the mark is
detected.
• IP67 watertight construction with M12
rotary connector
• High response speed of 50 s and half
the size of OMRON's conventional
models.
E3M-V
Applications
Dependably Detects Marks on Laminated Sheets
The coaxial optical system ensures a long sensing distance and
stable sensing characteristics over a wide angle range, even for
objects that are distance-fluctuating or leaning at an angle, or for
laminated objects with marks, which conventional models have
difficulty in detecting
Auto-Teaching
An auto-teaching function automatically sets the threshold value
upon a Remote Control input while the workpiece is moving.
There is no need to position the mark at the optical spot.

Technical Guide
Glossy Sensing Objects
Incline the Sensor to detect glossy objects so that the Sensor will not
be influenced by the mirror reflection of light and to ensure the stable
sensing operation of the E3M-V.
