The Telemecanique XUSZMF172 is a mounting column/adapter sitting in the XUS light-curtain accessory family, used to support and align light-curtain arrays at the machine guard. It carries UPC 389119619175, which matches the unit-pack identifier you'll see on the factory carton and inbound-receiving paperwork.
Where it sits in a light-curtain build
As a light-curtain mounting column, it sets the optical path height and stand-off distance between the emitter and receiver columns on a fixed guard — getting the column plumb and the floor brackets to the rated footprint is what determines whether the curtain reaches its declared protective height cleanly.
