What the category means for fit
The XCPR2521G13: Medium Duty class positions this switch for applications like conveyor position sensing, machine guard interlocking, and general industrial limit switching where the mechanical load and cycle rate fall below heavy-duty foundry or mining service. The rating governs the actuator mechanism and internal contact block — not a current or voltage number, but the mechanical endurance and environmental sealing expected for the class. If your existing machine uses a Medium Duty limit switch footprint, this part drops in without bracket rework.
