The Omron F39-HJ0845 is a light curtain accessory — a component in the guarding system that creates an optical safety barrier around a hazard zone. Per the product description, it is classified as a LIGHT CURTAIN, meaning it is part of the emitter/receiver pair or mounting hardware that detects intrusion into a protected area.
Sourcing and procurement posture
For audit purposes, the active lifecycle status means the part is still in the manufacturer's catalog and has not been flagged for end-of-life, so it can be specified into a BOM without an immediate obsolescence risk.
