The XH3A-2041-4A is a rectangular connector array, edge type, mezzanine (board to board) that provides a robust solution to transition different board stacking heights while providing reliable connections between them. With features such as zero-insertion-force sockets and a flanged side guide, the XH3A-2041-4A helps increase design flexibility, reduce board-to-board transition time, and reduce overall inventory cost. The XH3A-2041-4A is an excellent choice for applications in the communications, aerospace, military, medical, commercial, and industrial markets.

Working Principle

The XH3A-2041-4A is designed with zero-insertion-force sockets that firmly hold contacts in place. By eliminating the need for force during socket connection, contact life and reliability is improved, while offering the convenience of an easy-to-install and replace connection. The flanged side guide of the XH3A-2041-4A provides extra stability, which is especially beneficial when transitioning boards with different stack heights. An anti-buckling device prevents misalignment during board seating. With a number of ground lines along the length of the board, the XH3A-2041-4A is designed to meet electromagnetic interference (EMI) requirements.

The tooling of the XH3A-2041-4A is designed for optimal performance. The interface of the socket contacts have a sharp edge to guarantee maximum contact force, while the receptacle has an improved contact interface to withstand higher mating cycles. A plastic shield provides EMC protection, and the mechanical stop prevents tool interference when mating. The board-to-board interface of the XH3A-2041-4A also includes a plastic bezel to protect against contaminants.

The XH3A-2041-4A is an advanced and dependable solution for applications that require reliable board-to-board connections with different stack heights. With a zero-insertion-force socket design, flanged side guide, and superior tooling technologies, the XH3A-2041-4A offers a reliable and cost-effective solution for a wide variety of applications in the communications, aerospace, military, medical, commercial, and industrial markets.
