Omron E3FA-LN12 2M is a pre-wired NPN background-suppression sensor with 200 mm red-light range, 0.5 ms response and IP67/IP69K.
The Omron E3FA-LN12 is a straight-type E3FA plastic-housing photoelectric sensor with NPN open-collector output and a 2 m pre-wired cable. It uses background-suppression sensing at 200 mm with a 624 nm red LED and a 300 × 300 mm white paper reference target; response is 0.5 ms, with Light-ON/Dark-ON selectable by wiring and IP67/IP69K protection. Current supply status is not established by the consulted manufacturer material and is recorded as Unknown.

Engineering suggestions require suitability checks for your installation.
A conveyor may need to detect passing products while limiting response to objects behind the sensing point.
Evaluate the 200 mm background-suppression range with the actual object and background geometry; verify the switching boundary and output logic during commissioning.
A fixture may need a compact sensor to confirm a part at a repeatable position.
Use the pre-wired E3FA sensor after checking target material, working distance, alignment and NPN input compatibility.
