Microminiature Strip - .100/.050" Contact Spacing
MT
Printed Circuit Board and
Card Mounting Frame Applications.
Contacts on .050(1.27) centers.
50-MIL STRIP microminiature connectors are de-
signed for space and weight saving applications in a
space conscious insdustry.The strip configuration
provides an extremely dense and reliable intercon-
nection device in a minimum profile package, giving
great application flexibility.
These connectors are available in many combina-
tions of length, contact spacing and terminations to
give designers maximum latitude in their packaging
and interconnection solutions. They have been used
successfully on printed circuit boards and card
mounting frames. Because of its configuration, the
50-MIL STRIP connector is particularly suited for
mounting with high strength epoxy adhesive. In
lengths over 2" (50.80) guides, rails or other
systems should be used to assure alignment.
50-MIL STRIP connectors use either a flexible
insulator of polyester that can be mounted on
curved surfaces up to a radius of approximately
eight inches, or a more rigid insulator of diallyl
phthalate-giving the connector a higher temper-
ature capability. Up to 120 micropin contacts can be
held in a single strip on .050(1.27) centers. Guide
pins and polarizing devices are available. Special
termination with hookup wire is available to meet
specific customer requirements. Crimping hookup
wire to contacts before they are inserted is often
desirable in high density contact arrangements.
Color coded wires of any lenght in sizes #26 thru
#30 AWG solid and #26 thru #30 AWG stranded
can be harnessed by the factory.
