Conduction-cooled keying complies with VITA 1.6 for military and ruggedised systems

Manufactured by Birtcher, one of Schroff’s sister companies within the Pentair Technical Products Group, the CCK series of coding keys ensure that PCBs are inserted into the correct slots and also help to remove excess heat from the boards.

Whereas a conventional system can accommodate keying between the front panel and the card guide, the mating halves of the CCK coding keys are attached to the rear edge of the board and the backplane of the system.

The devices are fully compliant with the VITA 1.6 standard, which defines a keying system for VME64x boards and backplanes in an IEEE 1101.2 conduction-cooled environment. In addition, they can be used successfully in IEEE 1101.10 non-conduction-cooled applications where there is no front panel.
Available in six different configurations, the coding keys feature a choice of gold or clear chemical film finish and can be specified with metric or imperial threads. They are supplied individually or in kits containing two mating pairs, with mounting screws and washers included.
