The Omron F3SJ-A1260P25 is a Type 4 safety light curtain from the F3SJ-A series, rated for hand protection with a 25mm detection capability per the datasheet. Its 1260mm protective height and 20mm beam pitch (63 beams total) cover a vertical access zone typical of machine loading stations or robot cells. The 0.2m to 9.0m operating range gives flexibility for both compact and extended guarding layouts. Supply is 24VDC, standard for safety circuits in industrial control panels.
The 25mm detection capability defines the smallest object that reliably breaks a beam — finger detection is typically 14mm, so this is a hand-protection curtain. For applications requiring finger or toe detection, step down to the 14mm variant in the same F3SJ-A family. The 1260mm protective height matches a 1.26m vertical zone; if your hazard opening is taller, you stack multiple curtains or choose a longer model. Blanking and muting functions are built in per the spec listing — blanking lets you ignore fixed obstructions (e.g., a machine frame passing through the field), while muting temporarily suspends the curtain during a defined material pass cycle. These are configurable via the controller, not hardwired, so verify your safety PLC or safety relay supports the muting logic.
The F3SJ-A1260P25 ships as a bulk pair (emitter and receiver) with no controller included. You will need a separate F3SJ controller or a compatible safety relay/PLC with OSSD inputs. The 24VDC supply must be from a PELV/SELV source per the safety standard. The IP65 rating allows hose-down cleaning, but verify the connector and cable entry are also rated for the same ingress level — the curtain body is sealed, the cabling may not be.
