Technical Overview
The Omron E3FA-VN11 is a straight-type E3FA plastic-housing photoelectric sensor with NPN open-collector output and a 2 m pre-wired cable. It uses limited-distance reflective sensing at 10–50 mm with a 624 nm red LED and a glass (1.0 mm thick, 150 × 150 mm) 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.
A NPN red-light limited-distance reflective sensor with a 10–50 mm rated sensing range.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Conveyor detection against a fixed background
A conveyor may need to detect passing products while limiting response to objects behind the sensing point.
Potential use
Evaluate the 10–50 mm limited-distance reflective range with the actual object and background geometry; verify the switching boundary and output logic during commissioning.

2. Part presence at a machine station
A fixture may need a compact sensor to confirm a part at a repeatable position.
Potential use
Use the pre-wired E3FA sensor after checking target material, working distance, alignment and NPN input compatibility.
