What it fits and where it goes
The F39-HB1105 is a light curtain accessory that mounts to or interfaces with an Omron safety light curtain system. Because it is an accessory rather than a complete emitter/receiver pair, the installation step is mechanical: align the mounting holes, torque to the spec in the curtain's manual, and confirm the optical alignment with the supplied alignment tool (if included in the kit). No rewiring of the safety relay or PLC input is needed.
Sourcing and compatibility check
Before committing, confirm that the F39-HB1105 mates with your specific light curtain model. Verify the mounting bracket pattern and cable connector type against your curtain's manual.
