The E3F1TP21OMI: Operates on 10–30 VDC, switches loads up to 100 mA, with selectable Light-ON or Dark-ON operation via the connector pinout. The M12 4-pin connector and IP66 rating suit washdown zones or outdoor panels. Through-beam design achieves maximum range and immunity to target colour or surface, but requires separate emitter and receiver alignment — ideal for conveyor gaps, tall doorways, or long-axis inspection.

Frequently asked questions
When sourcing E3F1TP21OMI, what is the closest functional alternative?
The E3F1RP21OMI is a retro-reflective sibling sharing the same electrical and environmental specs but with 3 m range (vs 15 m) and requires a reflector instead of a separate receiver.
What is the length of the E3F1TP21OMI?
It has a length of 45 mm.
Will E3F1TP21OMI drop into a panel designed for E3F1RP21OMI without rewiring?
No. The through-beam pair requires two mounting points and clear line-of-sight, unlike the retro-reflective single-body sensor. The M12 connector and pinout are compatible, but mounting and alignment differ.
