The IFM KI5311 belongs to the KI series of cylindrical capacitive sensors for non-contact material detection. It is intended for detecting conductive and non-conductive targets such as liquids, plastics, powders and bulk materials. The sensor's cylindrical threaded format supports straightforward installation in tanks and industrial machinery. Capacitive detection also enables sensing through suitable non-metallic container walls. The KI5311 is suitable for presence, level and material-monitoring applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KI5311 uses capacitive sensing rather than mechanical target contact. This allows detection of metallic as well as many non-metallic materials. Typical targets include liquids, powders, plastics and granular products. The sensor can therefore be used for both presence and level monitoring. Sensitivity adjustment allows the detection point to be matched to the application.
Capacitive sensors are particularly useful for detecting media in tanks, hoppers and containers. They can detect material directly or through suitable non-metallic walls. This enables external installation in selected applications. The absence of moving parts reduces mechanical wear. The sensor can therefore support automated filling and material-handling systems.
The cylindrical threaded housing provides a conventional industrial mounting arrangement. Switching information can be connected to PLC or machine-control inputs. Local switching indication simplifies commissioning and troubleshooting. Adjustable sensitivity helps compensate for differences between target materials. The design is suited to continuous machine automation.

Capacitive technology reacts to changes in the electrical field around the sensing face. This enables detection of materials that cannot be reliably detected using conventional inductive sensors. Sensitivity can be adjusted according to the dielectric characteristics of the target. The technology is therefore useful for both conductive and non-conductive media. This flexibility makes KI-series sensors useful across many industrial processes.
The sensor should be positioned with sufficient clearance around its active sensing area. Sensitivity should be configured using the actual target material whenever possible. Deposits on the container or sensing surface can influence capacitive detection. Proper adjustment improves switching stability under normal process conditions. Mounting should also follow the installation requirements for the selected KI model.
