Omron E3S-CL Datasheet

Distance setting photoelectric sensor in metal housing
E3S-CL
• High water, oil and detergent resis-
tance
• Minimal black/white error for highest
reliability detecting different colored
objects (E3S-CL1)
Eliminates Background Influences with a
Hysteresis of Only 2% max. (E3S-CL1)
The hysteresis is the industry's minimum 2% max. (E3S-CL1).
As a triangulation measuring is used, objects behind the set-
ting distance cannot be detected. The sensor is insensitive to
the influence of background objects of high reflectivity, and
stable detects works on a conveyor from above. The hystere-
sis of the E3S-CL2 is 10% max. of the detecting distance (5%
max. for white paper).

What Is Distance Setting?
(Differences from other detecting system)
Distance-setting
When the sensing object moves in direction A, the center position
of the reflected light moves in direction B. This is received by the
2-split photodiode and the place where the incident levels are the
Fea-
same on the N and F sides is defined as the setting distance.
tures The object is detected by the incident circuit processing only when
N F, and is not detected when N F. Therefore, detection is stable
without being influenced by the work type and background ob-
jects.

Diffuse-reflective
Since the level of the reflected light is judged for detection , the
sensing distance varies with the color, material and/or size of the
Fea-
work.
tures
A malfunction may occur if there is any object of high reflectivity in
the background.
