What It Is & Where It Fits
The XCKD2127G11 is a Telemecanique-branded limit switch from Square D Sensors & Safety, classified as a Medium Duty Limit Switch. This category covers switches designed for repeated mechanical actuation in industrial control circuits — think position sensing on conveyor diverters, machine guards, or transfer line stops where the cycle rate stays moderate and the actuator sees steady, not impact, loads.
What the Category Means for Fit
Medium Duty Limit Switch classification tells you the mechanical life and electrical rating are sized for general-purpose machine control, not heavy foundry or press applications. In practice, that means it fits standard guard-door interlocks, presence-detection on packaging lines, and end-of-travel sensing on light conveyors. If your application involves direct cam actuation at high speed or repeated overtravel, you would step up to a heavy-duty form factor.
