What this light curtain does and where it fits
The Omron F3SJ-A0945P30 is a Type 4 safety light curtain from the F3SJ-A series, designed for hand and arm detection at a 30 mm detection capability. Its 945 mm protective height and 25 mm beam pitch (38 beams) define the guarded zone — sized for vertical access guarding on a machine opening or a press brake, not a full-body perimeter. The 0.2 m to 9.0 m operating range gives flexibility to mount the emitter and receiver across a work cell aisle or around a robot envelope.
Ratings that matter for the install
The 30 mm detection capability means this curtain catches fingers and hands reaching into the hazard zone — classified as hand/arm protection per IEC 61496. The 945 mm protective height covers a typical reach zone for a standing operator; pair it with a second curtain if the opening is taller. IP65 rating (dust-tight and water-resistant) lets it survive washdown in food processing or a dusty assembly line, though the -10°C to 55°C operating range rules out freezer applications. Powered by 24 VDC, which is standard for safety circuits in most control panels.
Built-in features for production lines
Blanking and muting functions are included on this model. Blanking lets you disable specific beams for a fixed obstruction (e.g., a part fixture) without stopping the machine; muting temporarily suspends the curtain during a material transfer cycle. Both are configurable without an external controller, which reduces wiring in a panel.
