Introduction
Product Overview
The Z-PACK 2 mm HM Interconnection System is a versatile board-to-board connection system designed for connecting free boards (daughterboards, printed circuit boards) to a fixed board (motherboard, backplane or back panel). It supports multiple configurations, including free board to fixed board connections and cable-to-pc board connections. The system utilizes miniaturized EON pin contacts and offers various connector module types with features like guiding and polarization posts, and optional Multi-Purpose Centers (MPC) for coding.
