The IFM KG0009 is a cylindrical capacitive sensor designed for non-contact detection and level monitoring. It provides an 8 mm sensing range with a normally open AC/DC output. The sensor operates from 20 to 250 V AC/DC and uses two-wire technology. Its M18 × 1 threaded PBT housing provides compact and secure mounting. A 2 m PVC cable and IP67 protection support industrial installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The sensor provides an 8 mm nominal sensing range. Its real sensing range is 8 ±10%, with an operating distance of 0 to 6.5 mm. Hysteresis is 1 to 15% of Sr. Correction factors are specified for glass, water, ceramics and PVC. The sensing range is suitable for common level and presence applications.
The KG0009 uses a normally open AC/DC output. Operating voltage is 20 to 250 V AC/DC. Continuous current ratings depend on AC/DC operation, with the documented output supporting higher AC current than DC. Switching frequency is 25 Hz on AC and 50 Hz on DC. Short-circuit and overload protection are not integrated.
The sensor uses an M18 × 1 threaded PBT housing measuring 84 mm in length. It is designed for non-flush mounting. A yellow LED indicates switching status. A 2 m PVC cable provides the electrical connection. IP67 protection supports industrial environments.
