Product details

The Omron E3Z-T81-L 2M is a through-beam photoelectric sensor from the E3Z series. It projects an infrared beam at 870nm over a 15m sensing distance, making it suitable for long-range object detection in conveyor lines, pallet handling, and automated material flow. The housing withstands high-pressure washdown and dust ingress, so it mounts in food processing or wet areas without an enclosure. Supply voltage is within the rated range, the cable connection provides 2m of wire, and the single-turn adjustment simplifies alignment. Response time is 1ms.

Through-beam requires an emitter and receiver aligned across the sensing gap. The infrared beam is invisible; use the alignment indicator during setup. The IP69K rating holds only when the cable gland is properly tightened.

Packaged in bulk for volume integration. This is an active catalog line; no last-time-buy concerns.

Frequently asked questions

What is the series and packaging of the E3Z-T81-L 2M?

It belongs to the Omron E3Z series and ships in bulk packaging.

Will the E3Z-T81-L 2M drop into a panel specified for the E3Z-R81-M1TJ-IL2 0.3M?

No. The E3Z-T81-L 2M is through-beam, while the E3Z-R81-M1TJ-IL2 0.3M is retroreflective. They differ in sensing method, mounting, and required accessories (reflector vs separate receiver). Rewiring and mechanical rework would be needed.

What are the key ratings of the E3Z-T81-L 2M?

Through-beam, infrared 870nm, 15m sensing distance, 12-24V supply, 1ms response, IP67/IP69K, cable 2m, operating temperature -25°C to 55°C.
