A modular interface system having a modular SPE-based bus system with an SPE-based twin-core line and a plurality of SPE-based connectors, wherein a plurality of modules, each of which has an SPE-based connector, can be electrically and mechanically coupled to the SPE-based bus system by means of the SPE-based connectors.

An adapter system suited suitable for use in association with legacy military connectors including an adapter board assembly and an electrical cable connector. The adapter board assembly includes a pair of legacy connectors and a high density connector. A connector attachment block is attached to the adapter board assembly. The electrical cable connector includes a first side coupling assembly, a second side coupling assembly and a cable member extending therebetween. The first side coupling includes a connector matingly electrically attachable to the high density connector of the adapter board assembly, and a housing attachable to the connector attachment block. The adapter board assembly and the electrical cable connector are likewise separately disclosed.

The disclosure relates to a system for electrically connecting two controller system modules (1) that are mounted side by side on a rail for holding controller system modules. The objective of the disclosure is to provide a system for connecting controller system modules (1) that is cost-effective, space-saving, and allows easy installation. This objective is solved by a system including a connector (3) including a connector housing, which is connectable to mounting portions (8,12) of the two controller system modules (1), thereby connecting the controller system modules electrically and mechanically.
