Overview
The XU2M18AP20D is a Schneider XU2 through-beam photoelectric sensor set — transmitter and receiver in one order code — rated for a 70 m sensing distance on a 12-24V DC supply with a PNP output. Housed in an M18 threaded metal barrel sealed to IP67, it switches at 30 Hz with a 15 msec response time and terminates in a 4-pin M12 connector.
How it compares
Against the XUB1APANM12 retroreflective sensor, the XU2M18AP20D delivers a 70 m through-beam range versus 5.5 m, but switches at 30 Hz versus 500 Hz — pick the XU2 for long-axis alignment gates and the XUB for high-speed retroreflective detection on conveyors.
Lifecycle and sourcing
The XU2M18AP20D is a current Schneider catalogue sensor; lead time is typically short, and an RFQ confirms availability for the exact build variant.
