What this light curtain guards and how
The Omron F3SJ-A1580P25-TS is a type-4 safety light curtain from the F3SJ-A series, rated for hand protection with a 25mm detection capability. That 25mm figure means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1. The 1580mm protective height and 20mm beam pitch (79 beams total) define the guarded area, covering a vertical plane from 0.2m to 9.0m operating range.
Blanking and muting — what they mean on the line
Built-in blanking and muting functions let this curtain tolerate fixed obstructions (like a conveyor frame passing through the field) or temporarily suspend the safety output during a material pass-through cycle. That avoids nuisance trips that stop production. These are configurable features, not fixed — the integrator sets them during commissioning.
The lifecycle record shows this part is in the end-of-life hot phase (EOL hot). That means the manufacturer has announced discontinuation; last-time-buy windows may be closing or closed. If you need a production-part replacement, let us know the application details and we can research the official successor or a functionally equivalent alternative.
