FCI MezzoStak™ Connectors

FCI MezzoStak™ 0.5mm Pitch Board-to-Board Mezzanine Connectors feature a hermaphroditic "mates-to-self" design using the same part number for both mated sides, reducing inventory and administration costs. MezzoStak connectors ensure highly reliable performance with guidance "scoops" to permit easy mating when mis-aligned, polarization to prevent mis-mating, dual-point mating for redundant electrical contact, and high retention force to ensure a secure connection. FCI MezzoStak 0.5mm Pitch Board-to-Board Mezzanine Connectors are suited for portable & mobile electronics, medical & instrumentation, hand-held terminals, automatic identification & data capture, sensors, military, communications & networking, motor vehicle, and metering & energy applications.
