E32/E3X

Fiber optic sensors

E32/E3X

• wide portfolio range of fiber sensing

heads

• application oriented design for long

operational lifetime

• high precision in design and manufac-

turing for high application accuracy

• fiber and amplifier designs for easy in-

stallation and set up

Features

Long operational lifetime

Ensuring that the sensors do not fail during produc-
tion and require only minimal service attention en-
hances productivity and reduces maintenance costs.

1. Models with enhanced protection and tested 

resistance against harsh environments

• Tested resistance against aggressive chemicals, 

extreme temperatures, low pressure (vacuum), 
mechanical abuse

2. Preventing fiber breakage

• Housing construction preventing protruding 

cables (e.g. square shape, side view models)

• High flex fibers with 1mm bending radius for close 

wall mounting

• Robot fibers tested with more than one million 

bending cycles

• Protective metal or plastic tubes

3. Operational stability

• LED power control against aging effects
• Auto-threshold control for enhanced 

compensation of power decrease, e.g. 
through dirt on lenses

Easy to set up and adjust

With minimal time required for mounting the fibers 
the productivity can be enhanced for machine build-
ers and the easy setting of the amplifiers simplifies 
production changes for machine users.

1. Easy-teach amplifiers or manual adjusters

• Easy manual adjustment by potentiometer
• One-button auto teach for in-process dynamic 

teaching, or two-point object teaching

2. Wide range of easy-to-mount fibers

• One-screw-mount fibers with hexagonal back
• Square shapes for simple surface mounting
• Side view for simple alignment
• Application-optimised housings (e.g. fork shape 

for label and foil detection, tube for liquid level 
detection, etc.)

High accuracy in smallest size

OMRON’s precise manufacturing processes with in-
spection system supported alignment of the fibers 
and lenses achieve minimal tolerance variations in 
all standard models and allow the detection of the 
smallest objects and height differences of less than 
100 µm.

• High beam axis accuracy for side view models 

through precise fiber bending or angle mirror 
surface treatment

• High spot evaluation precision on coaxial models 

through equal fiber distribution

• Accurate distance setting through precise lens 

and beam alignment
