SK2-2 is an M23 Elite Checkmate circular DIN connector designed for demanding industrial applications requiring robust signal and power transmission. The connector features a quick-locking Checkmate coupling system with distinctive alignment arrows and Lock/Unlock symbols, available in Power, Signal, and Hybrid configurations. Power Series models support up to 30A maximum current at 630V maximum voltage with 14-16 AWG wire sizes, while Signal Series models handle 10A maximum current at 160V (12 position) or 125V (16-17 positions) with 18-26 AWG wire sizes. The housing is constructed from zinc die-cast material with nickel plating, and the connector is rated IP67 with 360° shielding for environmental protection. Operating temperature range is -20°C to +130°C, with vibration and shock testing up to 20g and 50g respectively in three axes. This connector is ideally suited for servo drive encoder feedback, packaging, robotic, printing, machine tool, medical, and automation environments where compact, reliable control signal transmission or power delivery is required.
