M12 Capacitive Level Switch Connector 316L Liquid Level Sensor PEEK Probe Water Tank PNP NPN

The WINSTON M12 capacitive level switch is engineered for high-precision point level detection across diverse industrial environments. Built with a food-grade PEEK sensing probe and rugged 316L stainless steel housing, this compact level sensor features maintenance-free operation with no mechanical moving parts. Utilizing advanced frequency-sweep capacitive technology, it reliably monitors liquids, viscous slurries, powders, and bulk granules in storage tanks, silos, and processing pipelines. The sensor features an innovative one-key calibration via learning wire in under 1 second, paired with an intelligent PNP/NPN and NO/NC adaptive single-switch output (5-30 VDC supply) to minimize spare part inventory. With IP67 ingress protection, -40 to 85°C operating range, rapid 0.1-second response time, and ±1mm repeatability, it provides robust, reliable overfill and dry-run protection for food & beverage, chemical, water treatment, and automated packaging machinery.
