KV class connectors are the perfect answer to the high-vibration and high-temperature (260°C) requirements encountered in aircraft engines and other harsh operating environments. In addition, the trend in aviation to minimise weight and to optimise the ergonomics of wiring harnesses make KV class connectors the perfect solution with their integrated backshell. It is because of these special features that the KV class is the solution adopted for new engine developments.

ELIO^® AQ is a metal adaptor for ELIO^® optical contacts, for size 8 Quadrax cavities. It enables a standard ELIO^® optical contact to be inserted into the size 8 Quadrax cavity of several connector types. The ELIO^® AQ adaptor is already available for connectors in the MIL-DTL-38999/EN3645 series III, ARINC 404 and ARINC 600 ranges. All insert arrangement types with a size 8 cavity can thus be fitted with a fiber optic connection using the ELIO^® optical contact.

Derived from the AerioMil MIL-DTL-38999 and VG96912 standards, Souriau’s HD range, based on a standard design, was specially developed to withstand the harshest operating environments (shock, vibration, high temperature etc.). By doubling the number of contacts for each size of connector, Souriau HD is the response to the increasingly stringent demands of weight and size reduction.

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.

Souriau has developed and released gauge #8 quadrax contacts which have demonstrated in an operational environment that they are compatible with communication protocols requiring up to category 6. These protocols include those for the flagship quadrax application which is, of course, Ethernet in harsh operating environments.

Souriau has extended its RoHS Zinc Nickel protection to its latest range of miniature circular connectors, the micro38999 series. This gives the range three key advantages: record compactness on the market of connections for harsh environments (-50% of compactness as compared with size 9), specifications in line with a military standard and an environmentallyfriendly RoHS protection.

SOURIAU has obtained K1 qualification of new 8NA Series junction boxes, especially developed for EPR programs (European Pressurized Reactor).

SOURIAU’s black Zinc Nickel version enables users of industrial and aeronautical equipment to comply with the latest RoHS directives. It can guarantee the same electrical and physical characteristics as the cadmium solution, particularly in terms of salt spray resistance (500 hours). In addition, an RoHS Zinc Nickel 851 connector can be mated with a cadmium connector without generating a galvanic couple; the same is true of accessories such as adaptors.

To meet the growing demand for small waterproof connectors for on-board railway equipment, SOURIAU has developed a special connector: the SMS IP. Designed to meet railway standards, the SMS IP combines compactness and safety: IP 67 sealing, operating voltage up to 500 V and compliance with the most demanding fire and smoke standards. SMS IP is intended for on-board applications such as lighting, door controls, detectors, air conditioning programmes, the SMS cabs etc..
