The XUB4BPANM12 is a Telemecanique XUB-series diffuse photoelectric sensor in a cylindrical M18 housing. Diffuse detection means the emitter and receiver share the same optics — it senses objects by the light reflected back from the target, no separate reflector or receiver needed. That makes it a straightforward pick for presence detection on conveyors, packaging lines, or material-handling stations where you don't want to run a second cable or mount a reflector.
Fit & Form Factor
The M18 cylindrical body is a standard industrial form factor — fits the common 18 mm mounting hole, uses the same bracket and connector patterns as hundreds of other M18 photoelectric sensors. If your panel or machine already has an M18 cutout, this drops in without rework. The diffuse sensing principle means no alignment of separate emitter and receiver; just point it at the target zone and set the sensitivity.
