Schneider Electric Telemecanique XS230SAMAL2 is a current-production inductive proximity sensor from the XS2 series. It's a cylindrical M30 threaded body in 316L stainless steel, unshielded, with a 40 mm sensing distance. Two-wire AC/DC output, normally open, rated 24–240 VAC/VDC and switches up to 300 mA. IP68 and IP69K ingress protection plus NEMA 4X — this sensor is built for washdown zones in food, beverage, and chemical processing.
IP68/IP69K means the sensor survives continuous submersion and high-pressure, high-temperature washdown. NEMA 4X adds corrosion protection, but note the operating temperature window: –13 °F to 185 °F. That's fine for most indoor process areas; don't spec it in a blast freezer or a hot dryer outlet. The 2-wire AC/DC circuit is convenient — only two conductors, no polarity worries, and it runs on anything from 24 to 240 V. But the 300 mA maximum load current is not enough to directly drive a contactor coil or a small motor starter. It'll feed a PLC input or a relay. Watch the voltage drop on long cable runs; at 300 mA a 2 m cable is fine, but if you extend the leads, the voltage drop adds up. Unshielded (non-embedded) means the sensing field extends beyond the sensor face — good for flush mounting in metal if you leave an air gap; not suitable for flush mounting in steel without derating the sensing distance.
