What the category means for fit
The XCKM515H29: Medium duty limit switches are specified for applications where the actuation force and mechanical life requirements fall between light-duty (e.g., door interlocks) and heavy-duty (e.g., foundry or mining equipment). This class typically handles moderate cycle rates and standard industrial environments without washdown or corrosive exposure — a fit for packaging lines, conveyor transfer points, and machine guarding where the switch sees regular but not abusive actuation.
