What the heavy-duty sub-category tells a field tech
The XCMD4102L5EX sits in the General/Heavy Duty Limit Switch sub-category — that means the housing and actuation are built for the vibration and impact you find on conveyor transfer points, machine tool doors, and nacelle access hatches where a standard limit switch would fatigue the lever arm or crack the body. Schneider Electric's Telemecanique brand covers the XCMD4102L5EX, so the switch carries the same IEC 60947-5-1 footprint and mounting hole pattern as other XCMD bodies — a direct swap for an existing XCMD in the same position without redrilling the bracket.
