Washdown-rated M18 inductive proximity sensor for hygienic lines
The TELEMECANIQUE XS218SAMAL2 is an M18 threaded cylindrical inductive sensor built for environments that demand hygienic washdown survival. Its 316L stainless steel body and nickel-plated finish resist corrosion from caustic CIP cycles and acidic process media. Rated IP68 and IP69K, it handles high-pressure, high-temperature spray cleaning and temporary submersion — common conditions in dairy, beverage, and pharmaceutical filling lines. The unshielded sensing face provides an adjustable detection range of 8 mm minimum to 15 mm maximum, allowing fine-tuned placement for pipe and valve position detection without physical contact. A 2-wire AC/DC output with NO contact form operates across a wide supply window of 24 to 240 V AC or DC, simplifying integration into legacy and modern control panels alike. Maximum load current is 300 mA, with an integral LED status indicator for quick commissioning and fault isolation. The prewired cable (2 m, bare wire ends) provides a simple termination point, reducing junction box clutter in tight panel or machine zones.
Lifecycle and compliance: active production with global certifications
Certifications include CCC, CE, CSA, RoHS, and UL Listed — covering North American and European installations without additional agency review. Compliance documentation (declaration of conformity, UL certificate, material declarations) is available upon request via RFQ. Operating temperature range of -13°F to 185°F ensures reliable performance in refrigerated environments and near hot CIP return lines.
Mounting and wiring for washdown zones
The M18 threaded body installs into a standard 18 mm mounting hole; a jam nut or weld boss secures the sensor. Because the sensing face is unshielded, maintain at least the nominal sensing distance (15 mm) behind the face for reliable detection — no derating needed for ferrous targets. The 2-wire bare-end cable connects directly to the control circuit. For DC supply, polarity is not critical on this 2-wire AC/DC design, but verify the load current stays under 300 mA and off-state leakage is compatible with downstream PLC inputs. Integral indicator lights confirm target presence and power-on without a test tool. NEMA 4X rating matches the IP68/IP69K ingress protection, so the sensor can be mounted directly in washdown zones without a protective enclosure. All exposed metal surfaces are 316L stainless or nickel-plated, resisting rust and pitting even in chlorinated wash environments.
