The Telemecanique XCKM108 is a medium-duty limit switch from Square D Switches & Sensors, cataloged under the Medium Duty Limit Switches category. This class of part provides position detection in industrial machinery, typically mounted on a machine frame or conveyor to sense the presence or absence of a mechanical stop or actuator.
What the category means for fit
Medium Duty classification positions the XCKM108 for applications where the mechanical actuation force and cycle life fall between light-duty (e.g., microswitches in control panels) and heavy-duty (e.g., foundry or mill-duty limit switches with metal housings). In a pulp and paper environment, this switch suits position sensing on dryer-section felt rolls or tail-threader guides — areas with moderate vibration and occasional washdown, but not direct chemical spray. The plastic or light-metal housing typical of this class survives the steam and the chemicals in a controlled enclosure, but it is not rated for submersion or continuous caustic exposure.
