With the SDK series, Conta-Clip offers a modular feed-through terminal block system with which different voltage levels up to 1000 V (UL 600 V) for rated currents up to 32 A can be provided. he maximum rated voltage is achieved through the optional use of separator, spacer and adapter plates, taking into account pollution degree 3 and the cable cross-sections used between 0.2 and 6 mm2. The two-part feed-through terminals for sheet thicknesses of 1 to 4 mm are available in versions with a screw connection system or with a screw/solder connection system designed to meet the requirements for encapsulated devices. The company supplies PE foam seals and potting plates to match the screw/solder connection system, which prevent the potting compound from leaking through the mounting openings when potting wired and tested devices. The feed-through terminals are strung together to form multi-pole units using housing pins. The terminals are available in a standard version with or without latching pins and in a locking version with latching pins and locking tongue for connecting the feed-through modules inside and outside the housing.
