Product Overview
The Omron E3FA-DP13 is a diffuse-reflective photoelectric sensor in the E3FA family, with a 1 m sensing range on white paper and a PNP output on an M12 4-pin connector. The 'DP' marks diffuse / PNP, and the '13' suffix is Omron's 1 m / M12 code, distinguishing it from the 100 mm (DP11), 300 mm (DP21 / DP12), and shorter-range M12 siblings in the E3FA family. The M18 ABS body carries a bright red LED emitter, a large sturdy sensitivity knob, and a visible orange LED for power and output status. It is the standard pick for short- to mid-range part detection on conveyors, feeders, and small assembly stations where an M12 patch cord is preferred.
Why diffuse reflective at 1 m
Diffuse-reflective sensors detect light reflected off the target, so they only need wiring on one side and no reflector opposite the sensor. The 1 m range is the right point for detecting a part on a 600-800 mm wide conveyor, a workpiece on a small index table, or a board exiting a feeder. Targets outside the rated 1 m window may still trigger if highly reflective, so for shiny or mirror-like surfaces the BGS E3Z-LL or a retro-reflective sensor is usually a better fit.
Choosing the right E3FA diffuse variant
E3FA-DP13 is the 1 m PNP M12 version. The 300 mm PNP pre-wired sibling is E3FA-DP12, and the 300 mm PNP M12 sibling is E3FA-DP21. The NPN twin at 300 mm pre-wired is E3FA-DN12. The through-beam pair in the same family is the E3FA-T series. Pick the E3FA-DP13 when 1 m range, PNP output, and an M12 patch cord are the goal.
Before ordering
Set the sensitivity so the target reads strong at the actual installation distance, not at the rated 1 m. Allow for a 30-50% derating on dark or matte surfaces, since the 1 m spec is on white paper. Pick an XS2F-M12 / M12-4A patch cord in the right length. For IP69K washdown environments, move to the E3FB series, the stainless steel M18 equivalent.

Buying Checklist
- Choose E3FA-DP13 for 1 m range, PNP, and an M12 patch cord.
- Choose E3FA-DP12 for 300 mm range with a pre-wired 2 m cable.
- Choose E3FA-DN12 for 300 mm range in NPN with a pre-wired cable.
- Choose E3FA-DP21 for 300 mm range in PNP with an M12 connector.
- Choose the stainless E3FB series when the panel needs IP69K washdown.
- Confirm the actual sensing distance against target colour and reflectivity.

FAQ for E3FA-DP13
What is the difference between E3FA-DP12 and E3FA-DP13?
E3FA-DP12 is a 300 mm PNP sensor with a pre-wired 2 m PVC cable. E3FA-DP13 is a 1 m PNP sensor with an M12 4-pin connector. They are at different ranges in the same E3FA family. Pick DP12 for shorter reach and direct panel wiring; pick DP13 for the longer 1 m range and an M12 patch cord.
Is the E3FA-DP13 NPN or PNP?
The E3FA-DP13 is PNP. The 'P' in DP marks PNP, and the 'D' marks diffuse. For the NPN version of a similar M12 diffuse sensor, look at the E3FA-DN twin in the same M12 connector family. Pick the part that matches the input polarity of the target PLC.
Can the E3FA-DP13 detect a black or shiny target?
Yes, with a derating. The 1 m range spec is on white paper. Black rubber or matte surfaces typically read at 50-70% of that, so plan the mounting distance at 500-700 mm. Shiny or mirror-like targets can read erratically; for those, use the BGS E3Z-LL or a polarised retro-reflective sensor instead.
