The housing Ø 30 mm and active surface are PTFE (FDA 21 CFR 177.1550), enabling high chemical resistance in challenging environments and making it suitable for applications in process and food-adjacent settings. The 3‑wire DC sensor provides a normally open output (NPN on the K variant) and operates from 10–35 V DC, delivering up to 400 mA with a maximum voltage drop of 2.0 V. It supports switching up to 200 Hz, with IP67 protection and EN 60947-5-2 compliance, and includes a built‑in protective circuit. A 2 m PVC cable (3 conductors, 0.75 mm²) feeds the sensor, which carries yellow\/green LED indicators for status. The model is catalogued as Art.-No. 814620 for the NPN K‑variant (KAS-80-30-S-K-PTFE) and 814 450 for the PNP variant, with a 30 mm housing diameter and a flush-mountable design for streamlined installation. Designed for dielectric materials such as plastics and other non-conductive media, this KAS‑80 series sensor emphasizes chemical resistance and food‑grade materials while delivering precise, repeatable capacitive sensing in industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Rechner","offers":[{"title":"New","offer_id":46285503135978,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-kas-80-30-s-k-ptfe-capacitive-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
