Sourcing and lifecycle reality
Lifecycle status is active — no end-of-life notice or last-time-buy window on this order code. For a BOM freeze or a line-down swap, the F3SJ-A0485P20-TS is a current-production part you can spec into a new panel or pull as a direct replacement for an existing F3SJ unit. No obsolescence clock ticking yet.
What the ratings mean for fit
The '0485' in the order code typically indicates the detection zone height — 485 mm in this case, which covers hand and arm entry into a mid-sized hazard opening. The 'P20' suffix points to a 20 mm resolution, meaning it catches fingers (14 mm is finger-safe per IEC 61496-1; 20 mm catches hands and wrists). That resolution dictates the minimum object size the curtain sees, so match it to the smallest body part that could reach the danger point. Bulk packaging means the unit ships loose, not on a reel — standard for safety light curtains.
