Capacitive Detection Performance

The KQ6002 uses a capacitive measuring principle for detecting suitable materials without mechanical contact. Its nominal sensing range is 12 mm with a real sensing range of 12 ±10%. The sensor provides adjustable switching behavior through its programmable output function. Hysteresis is specified between 1 and 15% of the real sensing range. Switch-point drift is specified at -20 to 20% of Sr for controlled detection performance.

IO-Link Communication

The sensor incorporates an IO-Link communication interface for digital parameterization and diagnostics. It operates with IO-Link revision 1.1 and COM1 transmission at 4.8 kBaud. The device supports SIO operation when conventional switching is required. Its minimum process cycle time is 100.8 ms. This combination allows the KQ6002 to integrate easily into modern automation architectures.

Electrical Design

The KQ6002 uses a DC PNP electrical design with selectable normally open or normally closed output behavior. It operates from a 10 to 30 V DC supply and consumes less than 17 mA. The switching output supports a permanent current rating of 100 mA. Short-circuit and overload protection improve electrical reliability. Reverse polarity protection is also provided for safer industrial installation.

Mechanical Construction

The rectangular sensor measures 20 × 14 × 48 mm and is designed for non-flush mounting. Its housing is manufactured from glass-fibre-reinforced PBT, while the buttons use TPE-U material. The cover is made from glass-fibre-reinforced PC. A yellow LED provides switching-status indication. A 2 m PVC cable with 3 × 0.14 mm² conductors provides the electrical connection.
