No obsolescence clock ticking yet.
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.
