Industrial KAS-80-30-S-K-PTFE Capacitive Sensor

Industrial KAS-80-30-S-K-PTFE capacitive sensor from RECHNER Industrie-Elektronik is a PTFE-bodied device designed to detect dielectric materials with an adjustable sensing range from 0.5 to 30 mm. 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.
