What the general/heavy duty sub-category means for your line
The XCKJ561 is classified as a general/heavy duty limit switch. That means it's built for industrial environments where the switch sees repeated mechanical actuation — think conveyor diverters, machine tool carriage stops, or packaging-line gate positions. The 'heavy duty' label typically implies a metal housing and a robust actuation mechanism that handles higher overtravel and impact forces than a standard limit switch. Because it's a Telemecanique branded unit from Schneider Electric, the XCKJ561 follows the same form-factor and mounting footprint as the rest of the XCKJ series. If you're replacing an older XCKJ variant, the mounting hole pattern and actuator interface should match without panel rework.
