The F39-HJ0370 is a light curtain from Omron's series * — a safety-rated optical guard used to detect personnel or objects entering a hazard zone. Active in production, so it's a current BOM line, not a last-time-buy scavenger hunt.
What you get
Supplied in bulk packaging — loose units, no individual retail carton. That's the standard for panel-builder or integrator orders where the part goes straight into a machine build, not onto a shelf.
