The Omron E3S-AD31 is a diffuse-reflective photoelectric sensor with a PNP open-collector output. Sensing range is 10 to 200 mm on a 10-30 VDC supply, sourcing up to 100 mA. Housed in PBT with a 2 m cable, it offers Light-ON/Dark-ON selectable switching — a single sensor covers both background and foreground detection needs without a separate amplifier. Rated for -25 to 55 °C ambient, it fits conveyor, packaging, and material-handling stations where a short-range presence check inside a machine guard is needed.

Frequently asked questions
Can the E3S-X3CE4 replace the E3S-AD31 without rewiring?
Not confirmed. Both are photoelectric sensors in the same category, but the E3S-X3CE4's output type and sensing method are not detailed in available data. Verify output configuration (PNP/NPN) and wiring before substitution.
