To meet next-generation data-processor requirements, ERNI developed a high-speed differential hard metric connector system that enables data rates of over 20 Gbits/s with quality crosstalk behavior. The ZDplus connector combines optimized signal routing with the press-fit termination of a female connector option, which helps improve layout on daughtercards. The connector offers 40 differential pairs per linear inch. Low-noise, dual-beam leaf contacts use one ground blade for every signal pair, with a 2.5-mm pitch from wafer to wafer. In-line ground arrangement at termination and the grounding shield help improve pre-alignment guide and polarizing features via four rigid blades in all modules. The ZDplus connector is backward-compatible with the company’s ERmet ZD male connector. Three- and four-pair female versions are available.
