SEARAY Mezzanine Connector Family

Molex SEARAY 1.27mm Board-to-Board Connectors were developed for the high-performance mezzanine connector market to accommodate low-profile applications not suitable for HD Mezz™ products. With superior electrical and mechanical features that are cost-competitive, the Molex-patented solder charge results in better process yields. The series includes plugs and receptacles with data rate speeds up to 10Gbps. For higher data speeds, the SEARAY Slim plugs and receptacles offer speeds to 12.5Gbps.
