Sensor overview for panel integration
The Omron E3Z-LS66 is a distance-settable photoelectric sensor using a red LED (680 nm) light source. It offers both background suppression (BGS) and foreground suppression (FGS) modes, with a sensing range of 40 to 200 mm on a white paper target and 40 to 160 mm on black paper. The control output is an open collector, NPN or PNP selectable via a Light-ON/Dark-ON switch, rated for 100 mA max at up to 26.4 VDC. Power supply is 12 to 24 VDC, and current consumption is 30 mA max.
Installation and wiring notes
The control output is an open collector rated for 100 mA at 26.4 VDC max, with residual voltage 1 V max. The output can be configured as Light-ON or Dark-ON via a switch. Power supply must be 12 to 24 VDC with ripple ≤10%. Differential travel is 10% of set distance maximum. For reliable background suppression, the sensing range varies with target color and reflectivity; best performance is achieved with the distance set within the white paper range.
