Overview
The IFM KI0205 capacitive sensor (part number KIE2015-FBOA/NI) is a robust non-contact proximity detector engineered for reliable detection of metallic and non-metallic materials in industrial automation. Operating voltage ranges from 20–250 V AC/DC, making it compatible with both standard AC and DC control circuits. The sensor features a 3–15 mm measurement range with selectable NO/NC output, ideal for level monitoring and material presence detection applications.
Key Features
- Simple potentiometer setting of the sensing range

- High noise immunity
- Detects non-metallic materials, unlike inductive sensors which only detect metals
- Rotatable terminal chamber (C terminal box) by 90°
- Red LED output status indication for visual feedback

Typical Applications
Typical applications are in the wood, paper, glass, plastic, food and chemical industries. Capacitive level sensors from IFM are especially popular in the food sector. Packaging systems use capacitive sensors to check the presence of cardboard boxes, monitor the level of a medium in a carton (e.g. milk carton), and detect sheets of glass or wood panels on a roller conveyor. Capacitive level sensors work through non-metallic walls including plastic, glass and their varieties.
