Power offer for D38999 Series III*: power interconnection for harsh operating Environments
The new Souriau product range for power interconnection includes three shell sizes (19, 23 and 25) with
silvered contacts able to handle currents up to 800 amps. The design of these connectors is built around the use of Souriau´s Series III inserts and shells. This pedigree results in unrivalled performance under extreme temperatures and vibration, due in particular to the use of the ratcheting system and materials used and qualified for D38999 applications.
The The use of high power may generate interference, which can adversely affect the performance of the other communication systems found on the equipment. This is why Souriau offers its shielded Series III interface with an EMI ring as standard, along with different rear connection types (elbow or straight) enabling optimal grounding.
The design of these power connectors is fully modular. They can also be used alongside generators (APUs) near the engine block, or further downstream for electrical distribution between equipments. The backshells used are removable, so they can be adjusted at the last minute according to the space constraints encountered when starting wiring; or the elbow connector can be orientated according to the angle of the incoming cable, in order to minimise the residual tension of the cable on the connector.
Finally, these power connectors are available with RoHS Zinc Nickel protection, which is suitable for the 500 hours salt fog withstand and the 500 mating as stated both in the MIL-DTL-38999.
The modularity, materials used and standard interface mean that Souriau´s power product range meets the latest requirements dictated by the advent of hybrid vehicles and the need for greater power in order to cope with the proliferation of on-board equipment.
