What this accessory does on the line
The Omron F39-HB1345 is a light curtain accessory — a mounting bracket, protective housing, or interface component that extends or secures the sensing field of an Omron safety light curtain. It is not the emitter or receiver itself, but the hardware that positions or shields them on the machine frame.
Sourcing and compatibility
Supplied in bulk packaging — loose units, no retail box or individual carton. That keeps the per-unit cost down for panel builders and OEMs ordering in quantity. Compatibility depends on the light curtain series. The F39-HB1345 is designed for Omron light curtains; it fits Omron models that share the same mounting pattern and interface.
