What the category means for fit
Medium Duty Limit Switches are the workhorse position sensors for conveyor diverters, machine guards, and part-present stations. They handle moderate actuation forces and cycle rates — not the heavy foundry or press applications that call for a Heavy Duty metal-body switch. If your panel BOM calls out this category, the XCKP21H0P16 fits the form factor and mounting footprint of the standard XCKP series.
