The Z-PACK 2 mm HM Interconnection System is a two-part connector system designed for board-to-board connections, enabling the interconnection of free boards (daughterboards, printed circuit boards) to a fixed board (motherboard, backplane, or back panel). It also facilitates feeding this connection through the fixed board and allows for the connection of free boards to each other and cables to printed circuit boards, offering multiple configuration options. All PC board connectors utilize miniaturized EON pin contacts and can be stacked along the edge of the PC board to meet signal requirements. Connectors are equipped with guide and polarization posts, and some are available with a Multi-Purpose Center (MPC) for coding devices. This system is compliant with IEC917, IEC 61076-4-101, DIN 41626, DIN 43356, and IEEE 1301 standards.
