The KI0021 is a normally closed AC/DC capacitive sensor with a 15 mm adjustable sensing range. It operates from 20–250 V AC/DC and supports 25 Hz AC or 40 Hz DC switching. Its M30 × 1.5 threaded housing has an 81 mm length. The sensor uses a 6 m PVC two-wire cable for extended installation reach. IP65 protection and increased RF immunity support industrial applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KI0021 uses a 6 m PVC cable. This provides greater installation flexibility than the standard 2 m version. The cable uses two 0.5 mm² conductors. Brown and blue conductor identification simplifies wiring. The extended cable is useful when sensors are installed farther from control panels.
The sensor provides a 15 mm adjustable sensing range. Its real sensing range is 15 ±10%. The operating distance is 0–12.1 mm. Capacitive technology enables contactless target detection. The sensor supports correction factors for glass, water, ceramics, and PVC.
The sensor operates from 20–250 V AC/DC. Its normally closed output supports 250 mA continuous current. AC switching frequency is 25 Hz and DC switching frequency is 40 Hz. Short-circuit and overload protection are not provided. A fast-acting ≤2 A fuse is required.

The 6 m cable is the key configuration advantage of the KI0021. It allows the sensor to be mounted farther from the control cabinet. This can simplify machine layout. The two-wire connection reduces wiring complexity. The cable is suitable for conventional AC/DC sensor circuits.
The sensor provides increased immunity to conducted RF interference. This supports operation in electrically noisy industrial environments. The IP65 rating provides protection against dust and water jets. The M30 threaded body provides secure installation. The yellow LED provides local switching feedback.
