INTRODUCTION The Radiall DSX rack and panel series are multipin rectangular connectors used to electrically interface avionics equipment to equipment rack. Usually the plug is installed on the avionics rack and the receptacle on the equipment box. The mated locking mechanism is provided for the equipment and cabinet and is not a part of the connector pair. These connectors are widely used in applications such as: • Commercial/military aircraft and helicopters • Radar systems • Power circuits • In-flight electronic instrumentation • Flight simulators, etc. The following versions are offered: •...

DSX-F DSX-F receptacle connectors are available in four shell sizes (1, 2, 3 and 4) and are designed to be fitted with front release front removable contacts offered in pc tail and wire wrap termination. Inserts are offered with or without an interfacial seal (in both cases they are not and are fitted with a separator) and are available in the following contact arrangements: 106, 67, 57, 45, 40, 33C4, 26. DSX-F connectors are fully intermateable with connectors of the ARINC 404 shell type B and SAE AS81659 versions. DSX-DATA BUS These connectors have been designed to ensure the interconnection...
