Where the XCMD61500L2 sits in a panel
The Schneider Electric XCMD61500L2 is a general/heavy-duty limit switch from the Telemecanique XCMD line, sold under the Square D Switches & Sensors brand, listed on the Limit Switches line as a mechanical position-sensing element rather than a proximity or photoelectric device. In a control panel the part is used where a mechanical actuator confirms end-of-travel or position state — guard doors, conveyor diverters, hoist limits, packaging-machine indexing — with the body sized to take the mechanical wear that would burn out a proximity sensor in the same duty.
