Contact Versatility - Several types of Contacts can be
designed into a Connector Shell
26482 Series I connectors allow users to mix a variety of different
power, signal, and high speed contact styles within a common
insert.
The insert arrangement below is an arrangement for 26482 Series
I connectors. It shows the variety of contacts that can be designed
into a shell size 24. Typically, customers specify the contacts sizes
and power they require and chose an existing arrangement that fits
their needs. For special new configurations, engineering will design
the arrangement of contacts to fit wi
thin material and performance
criteria.
