The Molex 2034560003 is an ultra-high-density board-to-board connector engineered to deliver stable and reliable electrical and signal connections between two circuit boards within space-constrained applications. Featuring 699 contacts arranged in 11 rows with a 1.3mm pitch, this connector enables high parallel signal density, making it ideal for systems requiring massive data throughput such as high-end servers, switches, and networking infrastructure. The hermaphroditic "mirror mezzanine" design allows two identical connectors to mate without the need for male/female differentiation, simplifying inventory management while supporting flexible stacking heights of 5.5mm, 8mm, or 11mm. The connector supports data rates up to 56Gbps and incorporates 0.76µm gold-plated contacts for superior conductivity and corrosion resistance. Each contact is rated for 1A current and 30V voltage. Utilizing BGA surface-mount technology, the connector provides robust solder joints with high mechanical stre
