The Omron E3XNA8OMS is a fibre-optic amplifier from the ESX-NA series — a stand-alone amplifier unit that works with separate fibre-optic cable heads, not a self-contained sensor. It fires a red LED (visible, good for alignment) at 200 µs response time, so it can pick fast-moving parts or thin edges. Output is PNP, light-ON or dark-ON selectable, sourcing up to 50 mA. Power supply is 12–24 V DC, and the current draw stays low because the load current is the output limit, not the unit's own consumption.
Lifecycle is marked 'mature', which is Omron-speak for a stable, active product. No discontinuation notice tied to this code; you can spec it into a BOM without worrying about a surprise EOL next quarter. That said, always quote against an RFQ for firm lead time — availability can vary by region. Compliance documents (RoHS, REACH, UL) are not listed in the spec bundle we hold, so if you need a formal declaration, request it as part of the RFQ. The part itself is a standard industrial control device, not a medical or safety-rated component.
