Cannon Combo D^®
Combination D Subminiature connectors for the advan-
tages of an industry standard shield I/O interconnect, with
the flexibility of a customized special, designed for any
application.
This connector system is ideal for applications that require
optimization of space while improving overall shielding.
Combo D^® accomplishes this by combining multiple
interconnect types into one fully shielded product,
decreasing the number I/O interfaces and reducing the
possibility of EMI/RFI leakage.
