The KG5311 is a quasi-flush PNP normally open capacitive sensor with IO-Link. It provides a 0.5–9 mm sensing range for close-range applications. The sensor operates from 10–30 V DC and switches at up to 30 Hz. Its M18 × 1 threaded body provides compact industrial installation. The 12-LED indication family provides visual assistance for sensor adjustment.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KG5311 is designed for short-distance capacitive detection. Its 0.5–9 mm range suits compact machine applications. Quasi-flush mounting allows close integration with machine surfaces. The sensing point can be adjusted to suit the target. This provides flexible detection for industrial equipment.
The KG5311 family uses a multi-LED display to make sensor behavior easier to observe. This helps operators identify the switching point during commissioning. Visual feedback can simplify setup and troubleshooting. The display works alongside IO-Link communication. Together, these features improve sensor usability.
The sensor communicates through IO-Link. Parameters can be configured through an IO-Link master. Process data can be integrated into PLC logic. Diagnostic information can support machine maintenance. This makes the sensor appropriate for connected automation systems.

The M18 × 1 body supports straightforward mechanical installation. The quasi-flush configuration reduces sensor projection. High ingress protection supports demanding environments. The sensor operates across a broad industrial temperature range. Its compact form factor suits machine builders.
Visual indication helps users identify switching behavior. IO-Link provides a second method for parameterization and diagnostics. This can reduce commissioning time. The adjustable sensing range supports application-specific setup. The sensor is therefore suitable for production systems requiring repeatable configuration.
