Product Overview
The Omron E3FA-DN12 is an M18 cylindrical diffuse-reflective photoelectric sensor with a built-in amplifier. Pick it when the cabinet needs a small, general-purpose object-detect sensor wired to an NPN PLC input (or any 12-24 VDC sink input) on a quick-disconnect M12 cable.
The sensor reads 100 mm sensing range on white paper 100x100 mm (up to 300 mm on 300x300 mm white paper, the Omron catalog standard). The light source is a visible-red 624 nm LED (NOT a laser; the laser BGS sensor in the same E3FA housing is the E3Z-LL family). Light-ON / Dark-ON mode is selectable via a slide switch on the back of the sensor.
Output is NPN open-collector, 100 mA max at 26.4 VDC. Supply is 12-24 VDC plus or minus 10 percent at 25 mA max. Response time is 1 ms or less. The M18 threaded plastic body is IP67 (NOT IP69K -- the IP69K rating is the E3FB stainless line). Operating temperature -25 to +55 degrees Celsius.
The -12 suffix is the M12 4-pin connector variant on the Omron catalog; the bare E3FA-DN12 ships with a M12 connector on the rear face only (the field cable is supplied separately). The pre-wired 2 m cable variant is the E3FA-DN11; the PNP polarity twin in the same M12 connector body is the E3FA-DP12.

Best-Fit Applications
- Detect part-presence on a conveyor at 100 mm working distance, sink into a CJ / CP1 / NX digital input
- Pass / fail inspection of opaque parts coming down a chute before the next station
- Box-on-edge detection at the infeed of a case packer where reflected distance varies with box size
- Replace a worn-out E3FA-DP12 / DP22 in a washdown-light station where the IP67 plastic body is acceptable
- Quick-disconnect build where the sensor is wired to an M12 cordset and daisy-chained to other 12-24 VDC devices
- Pair with an XS2F / XS2W M12 4-pin cordset for a sub-15 m cable run to a CJ-series input card
Buying Checklist
- Pick the E3FA-DN12 when the cabinet needs an M18 NPN diffuse-reflective sensor on an M12 quick-disconnect cordset
- Pick the E3FA-DN11 instead for the pre-wired 2 m cable variant (no M12 connector required)
- Pick the E3FA-DP12 instead for the PNP (sourcing) twin in the same M12 connector body
- Pick the E3FA-VP1 (Transparent detection) when the build detects clear glass or PET bottles
- Pick the E3Z-D81 instead for a smaller M8 threaded body in tight machine spaces
- Pick the E3FB-DP22 instead for an IP69K stainless steel sensor in food / beverage washdown zones

FAQ for E3FA-DN12
What is the difference between E3FA-DN11 and E3FA-DN12?
Wiring. The E3FA-DN11 ships with a pre-attached 2 m oil-resistant PVC cable pigtail -- no M12 connector needed. The E3FA-DN12 (this SKU) ships with an M12 4-pin connector on the rear face; the field cable is attached with a separate XS2F / XS2W M12 4-pin cordset. Both sensors are otherwise identical: NPN diffuse, 100 mm range, M18 plastic body, IP67.
Is the E3FA-DN12 rated IP69K?
No. The E3FA-DN12 is IP67 rated only. IP69K (high-temperature, high-pressure washdown) belongs to the E3FB stainless steel sensor line. For a washdown-grade diffuse-reflective sensor in the food / beverage industry, use the E3FB-DN22 (NPN / M12 connector, SUS316L stainless body, IP69K).
Does the E3FA-DN12 use a laser or an LED?
Visible red LED at 624 nm -- NOT a laser. The visible red dot is just an aiming aid. The laser BGS (background-suppression) sensor in the same E3FA housing is the E3Z-LL family (E3Z-LL61 NPN / E3Z-LL86 PNP). For laser diffuse-reflective sensing at long ranges (up to 1 m), move to the E3Z-L series.
Can the E3FA-DN12 detect black or shiny objects?
Diffuse-reflective sensors can detect most opaque objects at the rated distance, including black and shiny surfaces. The detection distance shortens on black and shiny surfaces because less light reflects back to the receiver. For background-suppression (BGS) detection with consistent distance on color- or surface-variable parts, use the E3Z-LS61 / LS66 BGS sensor instead.
