What it guards and where it fits
The F3SG-4RR1600-25: This is a SENSOR LIGHT CURTAIN — an optoelectronic guarding device that creates an invisible detection zone across an opening. When an object (typically a hand or body part) breaks the beam array, the output switches to the OFF state, triggering the machine's safety circuit to stop hazardous motion. Mounts in the standard guarding footprint for access points on presses, robots, packaging lines, and assembly stations. The Box package indicates a complete emitter-receiver pair ready for installation.
Sourcing posture — quoted per BOM
The F3SG-4RR1600-25 is sourced to order against the BOM quantity through independent distribution channels. Because the lifecycle is active, the supply chain is stable: no premium for last-time-buy inventory, no risk of a board-spin replacement. The part number on the PO matches the nameplate.
