The SDK series is a modular feed-through terminal system for applications in device and enclosure technology. By combining coordinated system components, different voltage levels of up to 1,000 V (UL 600 V) for a rated current of up to 32 A can be provided. Optional use of isolating, spacer and adapter plates allows maximum-rated voltage up to pollution degree 3 for 0.2- to 6-mm² wire diameters. Two-piece feed-through terminals for 1- to 4-mm sheet thickness are available with a screw connection system or with a combined screw/soldering connection system, tailored to the requirements of encapsulated devices and ensuring maximum tightness in all applications.
