F3SJ-A0545P30 — Safety Light Curtain for Hand/Arm Protection
Its 30mm detection capability means it catches a hand or arm reaching into a hazard zone before contact occurs, meeting the requirements for finger and hand protection per IEC 61496. The 22 beams at a 25mm pitch create a 545mm protective height, covering a reach zone up to 9.0 meters away.
The 30mm detection capability is the critical spec: it determines the minimum object size the curtain reliably detects. For hand/arm protection, this meets the standard requirement; a finer 14mm pitch would be needed for finger detection. The 0.2m to 9.0m operating range covers both short-reach machine guarding and longer perimeter access points — the 9.0m maximum is the distance between emitter and receiver, not the sensing height. The 545mm protective height defines the vertical zone actually monitored; match this to the height of the opening or hazard being guarded. The 24VDC supply is standard for safety circuits and integrates with most safety controllers and relays.
Deployment Context — Where This Class of Part Goes
Safety light curtains like the F3SJ-A0545P30 are used to guard hazardous machinery — presses, robots, assembly lines, packaging equipment — by creating an invisible barrier that stops the machine when an object (hand, arm, or body) breaks the beam array. The blanking and muting functions allow for fixed or floating blanking of a beam to let workpiece material pass through without triggering a stop, and muting temporarily disables the curtain during a non-hazardous part of the cycle (e.g., a pallet entering a guarded zone). These features reduce nuisance trips in automated production lines while maintaining safety integrity.
