E3S-CL

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)

Features

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

Diffuse-reflective

Fea-

tures

 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 

same on the N and F sides is defined as the setting distance.

 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.

ture

Fea-

tures

 Since the level of the reflected light is judged for detection , the 

sensing distance varies with the color, material and/or size of the 

work.

 A malfunction may occur if there is any object of high reflectivity in 

the background.
