Omron E3U-GS-S DATASHEET
Photoelectric sensors in stainless steel fork shape housing
E3U-GS_-S
The fork shape of the E3U-GS photoelectric sensors provides
simple installation, positioning and alignment for the detection
of objects. The detergent resistant stainless steel (SUS 316L)
housing makes this sensor ideal for usage in frequently
cleaned areas.
• Detergent resistant stainless steel (SUS 316L) housing
• Slot sizes from 50 to 120 mm
• Visible red LED for simple and precise positioning
• Easy adjustment by potentiometer and L-on/D-on switch
