The XUB4APANM12 that's often cross-shopped? That's a diffuse reflective sensor, 150 mm range — a whole different animal. This XUVF30M8 won't drop into that panel without rewiring and a rethink. Fast nickel beats slow dime: know what you're buying. If the design calls for a through-beam, this is it; if it called for diffuse, move along.
Mounting: the fork is 30 mm x 30 mm, so it fits standard fork sensor brackets. Connector is a 4-pin nano — those are common on smaller Telemecanique sensors. Response time 1 ms, 500 Hz switching — fine for moderate speed lines. Don't leave it in direct sunlight above 140 °F; the painted aluminum will hold up in washdown but keep the connector dry.
