The ZCMD21 Telemecanique industrial limit switch (Multi-function Limit Switch ZCMD21) supports motorized or solenoid activation of small motors, thanks to an AC contact rating of 10 Amps and 250 Volts; moreover, its compact structure and multiple actuator options (plunger, roller lever) make it one of the most reliable limit switches designed for industrial automation. The ZCMD21 is equipped with snap-action contacts that help reduce arcing and wear as a result of its quick make/break operation. In machine tools, packaging lines, and material handling systems, the ZCMD21 is commonly used, meeting internationally accepted IEC standards ZCMD21 and 60947-5-1 for electrical and mechanical durability.
