Capacitive sensors
Balluff capacitive proximity switches (capacitive proximity sensors) are available in various configurations, with a wide variety of plug and cable options—plus particularly economical variants. They reliably detect objects over long distances and are suitable for non-contact detection of glass, wood, metal, plastic, composite materials, as well as liquids and bulk materials—even through plastic walls and other non-metallic packaging.
The portfolio includes versions with switching output, analog output, or an IO-Link interface, depending on the model.
Balluff capacitive proximity switches are available in multiple designs and materials, with adjustable sensing distance and IO-Link options for advanced diagnostics and parameterization.
Below is a practical overview of common Balluff capacitive sensor series, including connection type, primary housing material, maximum range, and typical cable length options.

Selection guidance: choose your sensing task (solid / liquid / bulk), then confirm the required range, material (stainless vs plastic), connection type, and preferred adjustment method (potentiometer / teach-in / IO-Link).
Capacitive proximity switches are used wherever non-contact detection is needed for non-metal objects, fill levels, or materials inside non-metallic containers—helping improve process stability and reduce mechanical wear.
Clear answers that help engineers and maintenance teams choose the right capacitive sensor configuration.
