What this sensor is and where it fits
The Telemecanique XU2M18MA230W is an M18 threaded tubular photoelectric through-beam sensor from the XU2 series, rated for a 15 m sensing distance. It operates on a supply from 24 to 240 VAC/VDC and switches up to 200 mA in dark-operate mode — meaning the output activates when the light beam is blocked, common for edge detection or break-beam applications in material handling and packaging lines.
Key ratings and what they mean for your application
Sensing distance of 15 m is suited for conveyor entries, door detection, or long-span through-beam guarding. Response time is 20 ms (on/off) and switching frequency 25 Hz, with dark-switched operate mode. Maximum load current is 200 mA, so it can drive a small relay or PLC input directly. The 2-wire connection means it's polarity-sensitive on DC; verify the load current stays above the minimum leakage current of the sensor (not stated, but typical for 2-wire AC/DC sensors). The supply range of 24 to 240 VAC/VDC gives flexibility for both control-transformer and direct line-voltage circuits. Enclosure is IP67 and NEMA 4X/12, with a nickel-plated brass barrel and PMMA lens. This suits wet washdown areas and mild corrosive environments — food and beverage, automotive paint, or outdoor installations. If you need higher chemical resistance, check the lens material compatibility.
