That 25mm figure means it catches a hand or finger reaching into the hazard zone — it's the standard resolution for hand-protection applications per IEC 61496-1. The 78 beams at 20mm pitch create a 1585mm protective height, so it guards a full vertical zone from about floor level to shoulder height on a standing operator. Operating range spans 0.2m to 7.0m, which covers most machine guarding distances from close-in press feeds to wider conveyor access points. The 24VDC supply is standard for safety circuits — matches what most safety relays and PLC safety inputs expect. ## Where it goes and what it handles IP65 rating means the housing and optics withstand washdown and dust ingress — suitable for food processing lines, packaging areas, or any environment where hoses are used for cleaning. Built-in blanking and muting functions let you configure fixed or floating blanking zones (to ignore a fixture passing through the beam) and muting sensors for material handling pass-through. That saves adding an external muting module — the logic is onboard.","metaTitle":"Omron F3SJ-B1585N25 Light Curtain, 25mm Hand Detection, 1585","metaDescription":"Omron F3SJ-B1585N25 safety light curtain with 25mm detection capability, 1585mm protective height, 78 beams at 20mm pitch, IP65, 24VDC.

It will not reliably detect a single finger (that requires 14mm), but it catches the full hand reaching into the hazard zone."},{"question":"What is the protective height and how do I size it?","answer":"The protective height is 1585mm, created by 78 beams at 20mm pitch. That covers a zone from roughly floor level to shoulder height on an average standing operator. For taller zones, you stack multiple curtains or look at the longer F3SJ-B variants."},{"question":"Can this light curtain handle washdown environments?","answer":"Yes, the IP65 rating means the housing is dust-tight and protected against water jets from any direction.
