Telemecanique 18 mm Cylindrical Photoelectric Sensor
The Telemecanique Sensors XU9M18MA230 is a cylindrical retroreflective photoelectric sensor built for industrial automation tasks that require non-contact object detection. Its 18 mm diameter housing suits standard mounting patterns on conveyors, packaging lines and machine-guarding stations.
Dark-on Solid-State Relay Output at 24–240 V AC/DC
The sensor operates in dark-on mode with a solid-state SPST relay, so the output conducts when the beam is interrupted rather than when it is reflected. Supply voltage spans 24 to 240 V AC/DC, but the fixed sensing distance of 3 m and the relay’s switching limits define the practical range for reliable detection.
Two-Metre Cable Termination for Direct Wiring
A 2 m pre-wired cable exits the housing, allowing direct connection to terminal strips or PLC inputs without separate connectors. Installers must route the cable clear of high-current conductors to avoid induced noise on the solid-state output and ensure the reflector is aligned within the 3 m sensing envelope.

Questions about this item
Should I pick the 18 mm diameter version or a different size for my mounting hole?
The sensor has an 18 mm cylindrical body, so it fits an M18 mounting hole; choose this size when your machine design calls for that specific thread diameter.
What does the 3 m sensing distance mean once the sensor is installed on a conveyor line?
It will reliably detect a standard reflector up to 3 metres away in dark-on mode, giving a clear on/off signal for objects passing through that range.
The spec says 24 to 240 V AC/DC — what does that voltage range actually cap in practice?
The solid-state relay output can switch loads across the full 24–240 V AC/DC supply range, so the sensor works directly on low-voltage DC or mains-level AC without a separate interface.
