The IFM KQ6006 is a capacitive sensor with a DC NPN output configuration. It provides a 12 mm sensing range for non-contact detection of suitable materials. The sensor supports selectable normally open and normally closed output behavior. IO-Link communication enables digital parameterization and diagnostics. Its 2 m PVC cable and compact rectangular housing support practical industrial installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KQ6006 uses capacitive measurement for detecting materials without mechanical contact. Its sensing range is 12 mm with a real sensing range of 12 ±10%. Hysteresis is specified from 1 to 15% of Sr. Switch-point drift is specified from -20 to 20%. The sensor is suitable for level and material-presence applications.
The KQ6006 uses an NPN output stage for systems requiring sinking-type sensor outputs. It operates from 10 to 30 V DC with current consumption below 17 mA. The switching output supports 100 mA continuous current. Short-circuit and overload protection are provided. Reverse polarity protection further improves electrical installation safety.
IO-Link 1.1 enables parameterization and diagnostics through the sensor interface. COM1 communication operates at 4.8 kBaud. SIO mode allows conventional switching operation. The minimum process cycle time is 100.8 ms. These features make the sensor suitable for digitally connected automation systems.
The KQ6006 measures 20 × 14 × 48 mm and is intended for non-flush mounting. The housing uses glass-fibre-reinforced PBT. Programming buttons use TPE-U and the cover uses reinforced PC. A yellow LED provides switching-status indication. The 2 m PVC cable provides direct connection to the control system.

The NPN output is suited to control systems designed for sinking-type sensor interfaces. This makes the KQ6006 useful where NPN wiring is required by the control architecture. Selectable output behavior provides additional flexibility during setup. IO-Link can provide digital access alongside conventional switching. The result is a versatile sensor for NPN-based automation systems.
The 2 m PVC cable supports installations where the sensor is positioned away from the control cabinet. The 3-wire configuration provides a straightforward electrical interface. The reinforced rectangular body can be installed in a variety of machine layouts. The yellow LED gives immediate visual switching feedback. Its compact dimensions allow installation in relatively restricted spaces.
