Product details

The Omron E3Z-D81 5M is a diffuse reflective photoelectric sensor from the E3Z series, with a 100mm adjustable sensing range (5mm to 100mm) using an infrared LED at 860nm. Output is PNP, selectable for Dark-ON or Light-ON, with a 1ms response time. The 5m cable provides permanent wiring, and the IP67 rating protects against washdown environments.

Wiring and mounting notes

The single-turn adjuster sets the sensing threshold; ambient light may affect the diffuse mode at the far end of the range. Supply range 12–24 VDC; output is a standard PNP sourcing signal compatible with most PLC inputs.

Frequently asked questions

What series does the E3Z-D81 5M belong to?

It is part of the Omron E3Z series.

Will the E3Z-D81 5M drop into a panel originally specified for the E3S-AR86 without rewiring?

No. The E3S-AR86 uses a connector; the E3Z-D81 5M has a 5m cable. Additionally, the sensing method differs (retroreflective vs diffuse), requiring a different mounting setup and a reflector for the E3S-AR86. Rewiring your panel will be necessary.
