Features

The Slimmest BGS (Background Suppression) Reflective Photoelectric Sensors in the World

Ultra slim at 3.5 mm and

black/white error of only

15%.

For example, the E3T-

FL1@ can stably detect a

black object at 12 mm

without being affected by a

white background at 20

mm.

OMRON provides BGS

performance sharper than

the previous Convergent-

reflective Sensors.

State-of-the-Art Technology Achieved Ultra Thin BGS

First Mounted Flip Chip in Industry

This shape and slimness make a massive contribution to

resolving issues, such as sensor space constraints.

Flip-chip mounting technology,

the ultimate in miniature

mounting technology for

attaching IC chips without

covering them in resin, is what

makes the slim structure of the

E3T-FL possible.

The E3T-FL is just 3.5 mm wide,

even with a two-part light

receiving element on the surface

of the circuit board and a signal

processing IC on the rear.

Flip-chip mounting of the IC has enabled the mounting volume to be

kept to the absolute minimum.

High-precision Alignment Technology

High-precision alignment technology is greatly contributing to

reducing installation and adjustment work onsite.

The E3T-FL sensing distances are subtly

controlled using high-precision alignment

technology, which aligns the optical axes of

more than one part.

The light receiving lens with its unique thin-

walled structure is automatically adjusted

inline to keep sensing distance fluctuations

to a minimum.
