The F3SJ-A0540P25-TS is a Type 4 safety light curtain from Omron's F3SJ-A series, designed for hand protection per IEC 61496-1/2. The 25 mm detection capability means it catches a hand or finger reaching into a hazard zone — the standard finger-protection class for press brakes, assembly stations, and robotic cells. The 540 mm protective height covers a waist-to-shoulder zone for a standing operator, with 27 beams spaced at 20 mm pitch so there are no blind gaps between beams. Operating range spans 0.2 m to 9.0 m, which suits most machine guarding applications from compact benchtop presses to large palletizing cells. The 24 VDC supply is standard for safety circuits; the IP65 rating means the emitter and receiver housings withstand dust ingress and low-pressure washdown, so this unit can be deployed in machining environments with coolant mist or occasional hose-down cleaning. Built-in blanking and muting functions reduce nuisance trips — blanking lets you ignore fixed obstructions like a conveyor frame within the field, while muting temporarily suspends the safety output during a defined material pass-through cycle. These features are configured at commissioning, not added later via external modules.
Deployment context
Mounts to standard machine framing or extruded-aluminum guard structures via the included brackets. The emitter and receiver align optically across the hazard zone; the 540 mm protective height and 9.0 m range cover most single-operator workstations. IP65 allows washdown but not high-pressure spray — for food-grade or heavy washdown environments, verify that IP65 meets your sanitation protocol before specifying.
