MEZZOSTAK™0.5MM HERMAPHRODITIC
CONNECTORS
DESCRIPTION
BOARD TO BOARD CONNECTORS
Robust, high density, 0.5mm pitch mezzanine
connector suitable for a wide range of high reliability
applications and demanding environments.
Innovative hermaphroditic design provides a precise
mating interface. Reduced product mix simplifies
customer connector qualification, documentation
and maintenance.
Precisely oriented surface-mount solder leads and
hold-downs enable highest quality assembly to
printed circuit boards
Two versions offer a choice between supplemental
PCB hold-downs or short overall length.
MezzoStak™connectors are supported by
MezzSelect™services and web-based design tools.
FEATURES & BENEFITS
Hermaphroditic design “mates to itself”
•Consolidates connector selection and documentation
•Polarization prevents mis-mating
Pressure-managed, dual-point contact mating interface
provides easier use, fault tolerance and added reliability.
Long 1mm minimum wipe assures reliable contact and
accommodates system mechanical tolerances.
Tactile feedback signals effective mating
Extreme operating temperature range assures reliable
performance between -40 and 125 degrees C.
Precise 0.08mm maximum SMT lead co-planarity eases
attachment of connector leads to PCBs
Optional hold-downs increase strength of PCB solder attachment
Footprint compatible with major competitors
