Omron E3Z-T81K 2M: PNP Through-beam (oil-resistant), 15 m range, 1 ms max. response, IP67 (oil resistance excludes cable/connectors) rated.
The Omron E3Z-T81K 2M is an E3Z compact photoelectric sensor using through-beam (oil-resistant) sensing over 15 m. It provides PNP output, operates from 12–24 VDC, and responds within 1 ms max.; enclosure protection is IP67 (oil resistance excludes cable/connectors). The model uses Pre-wired, oil-resistant cable, 2 m per sensor; reflectors for retro-reflective versions are ordered separately. Current supply status is recorded as Unknown.

Engineering suggestions require suitability checks for your installation.
A transport station may require a discrete detection signal as products pass a fixed point.
Align the sensor or through-beam pair with the actual target and background, then verify the PNP input and selected Light/Dark-ON logic.
A fixture may need to confirm a part or carrier before allowing the next machine step.
Set sensitivity and verify switching distance with the installed target, reflector or emitter/receiver alignment and surrounding surfaces.
