The Omron F3SJ-A0795P30 is a type-4 safety light curtain from the F3SJ-A series, rated for hand and arm protection with a 30mm detection capability. That 30mm figure means it catches fingers and hands reaching into a hazard zone — the standard finger/hand protection threshold per IEC 61496. The 25mm beam pitch and 32 beams create a detection plane 795mm tall, covering access to a machine opening or conveyor infeed. Operating range spans 0.2m to 9.0m, so it works on short-reach press applications and longer tunnel guards alike.
Deployment context and environment
The 24VDC supply is standard for safety circuits; plan for a dedicated safety-rated power supply or a PNOZ-style interface module. Blanking and muting functions are built in, so you can program fixed or floating blanking zones to ignore parts or tooling passing through the field, and use muting sensors to suppress the curtain during material transfer without a separate controller.
