E3T Pick up
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 (Patent Pending)
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 (Patent Pending)
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.
