ARINC 404 / MIL-C-81659B DSX connectors - Radiall - #4

Text version of the page

DSX INTRODUCTION 4 DSX rack and panel series aremultipin rectangular connectors used to electrically interface avionics equipment to equipment rack. Usually the plug is installed on the equipment rack and the receptacle on the avionics box. The mated locking mechanism is provided for by 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 -- MIL-C-81659B : connectors conforming to MIL-C-81659B including connectors listed on the QPL81659 DSX -- ARINC 404 shell type B : connectors conforming to ARINC 404 shell type B -- polarized shells DSX -- ARINC 404 shell type A : connectors conforming to ARINC 404 shell type A -- single shell (without polarization) DSX -- F : connectors for front release front removable contacts (receptacle only) DSX -- DATA BUS : connectors for interconnection of multiplexed digital links DSX EMI/RFI : shielded connectors DSX -- MIL-C-81659B These connectors fully conforms to MIL-C-81659B specification and are listed on the associated Qualified Product List. They are available in four shell sizes (1, 2, 3 and 4) which can respectively accept 1, 2, 3 and 4 inserts. Inserts are offered in various contact arrangements accommodating rear release rear removable signal (size 22 ), power (sizes 20HD, 16,12 and 5), coaxial (sizes 1, 3, 5, 7, 9 and 15), twinax (sizes 9 and 5), triax (sizes 5 and 9) contacts in crimp, wirewrap or PC tail termination. Fiber optic contacts are also offered. Both environmental and non environmental connectors are available. Mismating is prevented by a polarizing system which provides 216 polarizing positions. For MIL part numbers, applicable polarizing positions range from 00 through 99 only. DSX -- ARINC 404 shell type B These connectors are the commercial version. Compare to the military version : -- They use both size 20HD and size 20 contacts. -- They are non environmental. Inserts are fitted with a rubber separator on their wi-- ring rear face which does not provide sealing but wire protection. -- Removable size 5 and 9 coaxial contacts are not interchangeable with those of the military type. -- Insert retention plate is gold anodized instead of blue anodized on the military version. DSX -- ARINC 404 shell type A DSX -- ARINC 404 shell type A connectors are available in shell size 1 only. They accommodate ARINC 404 shell type B inserts ; only one insert can be installed in the connector shell. They have no polarizing system, mismating is prevented by keystone shaped shells. DSX ARINC 404 shell type A size 1 connectors cannot be fitted with any backshell. 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 fitted or not with an interfacial seal (in both cases they are not 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 MIL-C-81659 types. DSX -- DATA BUS These connectors have been designed to ensure the interconnection of multiplexed digital links used in military equipments. DSX -- EMI / RFI In response to the continuing development of electronic systems used in ever harsher environments, these connectors have been designed to improve the shielding effectiveness against electromagnetic and radiofrequence interferences (EMI/RFI) as well as electromagnetic pulses (EMP).
