What the sub-category means for fit
The XCMD3902L2: The General/Heavy Duty classification tells you this switch is designed for the mechanical endurance and environmental sealing expected on conveyor transfer points, machine guard interlocks, and material-handling equipment where the actuator sees repeated impact or vibration. It is not a precision limit switch for micro-positioning; it is a workhorse position sensor for presence and travel-limit detection in industrial enclosures and on-machine mounting.
