Product details

The Omron E3NXFA41AN2MOMS is a fibre-optic amplifier unit from the E3NX-FA series, built as the electronic half of a remote optical sensing pair — the amplifier sits in the panel while a fibre cable reaches out to the actual photoelectric work in the field. The housing is 10 mm wide, 33.5 mm tall, and 71.8 mm long — the same compact DIN-rail-friendly footprint carried across the series, so it lands in tight sensor banks without forcing a re-layout. The light source is a red LED, and the unit ships with a 2 m cable lead for direct wiring into the amplifier terminals inside the cabinet.

Electrical envelope and what the numbers actually govern

Load current is rated 100 mA on the switching output, which is the ceiling for the PNP driver into the downstream input card or relay coil — beyond that the output transistor derates, so watch it when fanning out to two parallel loads.

Speed, switching, and PNP wiring logic

Response time is 30 µs — fast enough for short-stroke indexing lines, label-detection at moderate web speeds, and small-part counting, but not a sub-microsecond vision-grade pick — which means cable-length capacitance on the 2 m lead will not meaningfully slow it. Switching mode is selectable between Light-ON and Dark-ON, so the same amplifier covers presence-detect and absence-detect logic without re-ordering a different SKU. The optical sensor output is PNP, sourcing the load to the positive rail — the wiring logic for a sinking-input PLC or relay coil referenced to common. The E3NXFA11AN2MOMS sibling in the same housing covers NPN.

Sourcing closure

This page targets the exact code E3NXFA41AN2MOMS: a PNP-output fibre amplifier with 30 µs response that drops into an existing E3NX-FA amplifier slot. The lifecycle stage supports a normal, repeatable procurement posture. Send the BOM line in as an RFQ — quoting against the order code returns a current lead-time and supply window against the same channel the rest of the E3NX-FA panel runs through, and keeps the amplifier on its documented spec rather than a parametric substitute the panel never validated.

Frequently asked questions

What is the closest functional second-source to E3NXFA41AN2MOMS?

Within the same E3NX-FA housing and electrical envelope, the closest variant is the NPN-output E3NXFA11AN2MOMS — it shares the 10 × 33.5 × 71.8 mm body, the 10–30 V / 100 mA ratings, and the 30 µs response, so it is a drop-in panel replacement only when the downstream input card is a sourcing type.

What is E3NXFA41AN2MOMS's width on this component line?

The recorded width is 10 mm.

What is E3NXFA41AN2MOMS's height on this component line?

The recorded height is 33.5 mm.

Will E3NXFA41AN2MOMS drop into a panel specified around E3NXFA512MOMS without rewiring?

E3NXFA512MOMS is a same-body, same-electrical-envelope variant in the E3NX-FA line, so the mechanical and electrical footprint is shared; the wiring pass depends on which output stage and cable detail each code carries, and that has to be confirmed against the actual sub-variant spec — not assumed from the series alone.
