The Telemecanique XUB2APBWM12R is a tubular photoelectric through-beam detector from the XUB series, built for presence sensing across a 15 m gap. It operates on 12 to 24 VDC with a PNP normally-closed output, switching at 500 Hz and responding in 1 ms on/off. The housing is threaded PBT rated NEMA 4X/12 and IP65/IP67, with a 90-degree side sensing position and an M12 4-pin DC micro male connector.
The 15 m sensing distance is the key spec for a through-beam pair — it defines the maximum separation between emitter and receiver, not a detection window. The 1 ms response time suits high-speed counting or registration applications, while the 500 Hz switching frequency confirms it can keep up with fast-moving targets. The PNP NC output is a sourcing (positive-switching) configuration that pulls the load high when the beam is unbroken; verify your PLC input card expects PNP logic before wiring. The M12 4-pin connector is standard for industrial sensors, but note the 90-degree side exit — plan cable routing accordingly if the panel layout expects a straight axial connector.
Integration Notes
Threaded 18 mm barrel with included mounting nut — installs through a standard 18 mm hole or bracket. The M12 male connector mates with a standard 4-pin female cordset; wire per the PNP NC pinout (pin assignments vary by cordset, confirm with the datasheet). The 3-wire configuration (V+, V-, output) is straightforward. The side-sensing head means the optical axis is perpendicular to the barrel axis — align the emitter and receiver so their side windows face each other across the 15 m gap.
