The Schneider Electric (Telemecanique) XU5M18MA230 is a cylindrical M18 diffuse photoelectric sensor in the XU5 series, with an 18 mm x 82 mm metal body and a right-angle sensing face that suits bracket mounting where a straight optical axis would foul the fixture. It accepts 24-240V AC and 24-240V DC supply, so a single catalog line covers typical control-panel mains and 24 VDC PLC rails without a variant swap. The output is a single-pole electromechanical relay rated 200 mA maximum load current in a 1NO contact form, which is enough to drive an interface relay, solenoid coil or contactor coil directly on the load side. Diffuse reflective sensing at up to 600 mm maximum range makes it a fit for object-presence detection on conveyor sections, bottle/cap presence on packaging lines, and pallet-end-of-line stop checks where the target itself acts as the reflector.
Switching performance and duty envelope
Response time sits at 20 ms and switching frequency at 25 Hz, which together cap the on/off cycle at about 25 operations per second — comfortably above most conveyor indexing and end-of-stroke applications, but not specified for high-speed counting or registration marks on fast web lines. Operating temperature runs from -13 °F to 131 °F, so the device will sit in a typical unheated cabinet or an enclosed outdoor skid without cold-start derating, but it is not the part to leave exposed to direct solar gain above that ceiling.
Mechanical and environmental build
The sensor carries a PBT case with a scratch-resistant lens and is rated IP67, meaning dust-tight and resistant to temporary immersion — the right enclosure for washdown areas provided the prewired cable exit is also sealed at the gland side. Standards listed are CE, CSA and UL Listed, the typical gate for North American industrial control panels and European machinery. Indicator lights are included on the body, giving a visible output-state signal for commissioning and fault isolation without a handheld programmer. Termination is a 2 m prewired bare-wire cable, which means the panel side needs a cable gland sized for the sensor lead and a terminal block — there is no M12 quick-disconnect variant on this order code.
How it sits against real siblings
The XU2M18AP20D leaves the AC/DC class entirely — DC-only, 12-24V DC, PNP output, M12 connector, through-beam set — so it is a different supply and output architecture rather than a functional substitute for the XU5M18MA230.
Sourcing posture
The XU5M18MA230 carries a current lifecycle stage and, with its 24-240V AC and 24-240V DC supply and 200 mA relay output on a metal body, covers most diffuse-presence jobs in a standard control panel.
