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. It runs on 24VDC and carries an IP65 rating, so the sensor body and optics withstand washdown and airborne dust in industrial environments.
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.
Lifecycle and sourcing posture
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. We source this unit through our independent distribution network — quoted to order against an RFQ. Availability and current pricing are confirmed at quote time. 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.
