It delivers a 100 mm sensing distance on opaque targets with a 0.5 msec response – fast enough to keep up with high-speed fillers and conveyors. The NPN output (100 mA max) ties into sinking-input PLCs or DC control loops. Supply is 10-30V DC, reverse-polarity and short-circuit protected on both power and output lines. The 2 m prewired cable has bare wire ends, ready for terminal blocks. With IP67 and IP69K ratings, it shrugs off washdown spray and high-pressure hot water – the kind of environment a bottling or canning line throws at it daily. ## NPN vs PNP – which sibling fits your panel The immediate cross-shop is the E3FA-DP112M: same body, same 100 mm range, same 0.5 msec response – but with a PNP output. If your PLC or load uses sourcing inputs (positive logic), the DP112M is the match; if you're terminating to a sinking/NPN input, the DN112M is the one. No mechanical difference, no wiring gotcha beyond the output transistor type. The E3FA-DN21 swaps the cable for an M12 connector and is otherwise identical – choose it if a field-replaceable connection is preferred for your maintenance plan. The E3FA-DP122M stretches the range to 300 mm but on a PNP output, so it's not a direct electrical swap. ## What the ratings mean in a real line The 100 mm diffuse sensing distance detects a 75 mm opaque target; response time is 0.5 msec, and IP69K rating enables washdown exposure.","metaTitle":"Omron E3FA-DN112M Photoelectric Diffuse Sensor, NPN, 100mm","metaDescription":"Omron E3FA-DN112M diffuse photoelectric sensor.

The DN112M is NPN; the DP112M is PNP. Mechanical footprint, cable length, and sensing performance are identical, but the wiring must match the load's positive or negative logic. Re-termination at the input card or relay is required to switch between them."},{"question":"What are the key protection features of the E3FA-DN112M?","answer":"The sensor includes output reverse polarity protection, output short circuit protection, and power supply reverse polarity protection.
