Omron E3Z-T81A 2M Through-beam emitter/receiver set Sensor

BrandOmron
Model IdentifierE3Z-T81A 2M
Official Part NumberE3Z-T81A 2M

Technical Overview

The Omron E3Z-T81A 2M is an E3Z compact photoelectric sensor using through-beam emitter/receiver set sensing over 10 m. It provides PNP output, operates from 12–24 VDC, and responds within 1 ms max.; enclosure protection is IP67. The model uses Pre-wired cable, 2 m per sensor; reflectors for retro-reflective versions are ordered separately. Current supply status is recorded as Unknown.

A PNP through-beam emitter/receiver set with a rated sensing range of 10 m.

Suggested applications

Engineering suggestions require suitability checks for your installation.

1. Conveyor or chute object detection

A transport station may require a discrete detection signal as products pass a fixed point.

Potential use

Align the sensor or through-beam pair with the actual target and background, then verify the PNP input and selected Light/Dark-ON logic.

Through-beam emitter/receiver set 10 m PNP 1 ms max.

2. Machine fixture presence check

A fixture may need to confirm a part or carrier before allowing the next machine step.

Potential use

Set sensitivity and verify switching distance with the installed target, reflector or emitter/receiver alignment and surrounding surfaces.
