What this Omron photoelectric switch is
The Omron E3FDS10B4P1 is a photoelectric switch in the E3F series, used for non-contact object detection in automated lines. It is listed as current production, so it remains an active BOM line for new builds and MRO spares.
As a photoelectric sensor, it requires a clear line of sight to the target and a reflective surface or separate receiver depending on the sensing mode.
