Omron E3U-GS DATASHEET

Photoelectric sensors in metal fork shape housing

Non-collimated Laser beam

Collimated Laser beam of E3U-GS_L_

E3U-GS

The fork shape of the E3U-GS photoelectric sensors provides

simple installation, positioning and alignment for the detection

of objects. The rugged metal housing provides protection

against damage and misalignment even for slot sizes up to

220 mm

• Slot sizes from 30 to 220 mm

• Visible red LED or LASER LD for simple and precise

positioning

• Rugged metal housing for protection against damage and

misalignment

• Easy adjustment by potentiometer and L-on/D-on switch

Features

Collimated Laser Beam (for E3U-GS_L_)

The collimated Laser beam of the E3U-GS_L ensures

that the detection accuracy can be maintained across the

complete slot width. This allows a detection of smallest

objects with dia 100 µm (E3U-GS5L-_).
