This standard float switch with a Ø12 mm switch tube offers a robust solution for applications requiring higher switching capacities and stable external mounting. The durable PVC housing combined with an NBR float enables reliable use in water-based and slightly oily media. The precisely operating reed technology ensures durable, power-free level detection. Vertical mounting is achieved via a large-area D75 flange, while the electrical connection via a standardized DIN 43650 connector ensures quick, secure integration.
