The Omron F3SJ-B1345P25 is a Type 4 safety light curtain from the F3SJ-B series, built for hand detection with a 25 mm detection capability. That 25 mm figure means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1. The protective height is 1345 mm, covered by 66 beams at a 20 mm pitch, so it guards a vertical access area roughly the height of a tall operator's reach. Operating range runs from 0.2 m up to 7.0 m, which covers most machine guarding distances on a production floor without needing a separate long-range model.
Where it goes and what it connects to
Runs on 24 VDC supply — standard for safety circuits in control panels.
Built-in features that matter on the line
This curtain includes blanking and muting functions. Blanking lets you optically bypass fixed obstructions (like a conveyor frame) within the field without disabling the whole curtain. Muting temporarily suspends the safety output when a workpiece enters the field under controlled conditions — useful for automated material feed stations. Both are configurable, so you don't need an external safety controller for basic pass-through applications.
