Circular Mil-Spec Connector Products

Souriau Group

Air Electro is a franchised, value-added distributor for SOURIAU’s MIL-DTL-26482 Series I and II connectors and their commercial equivalents, SOURIAU’s 851 Series, both of which provide high-reliability electrical connections in a wide range of critical harsh-environment applications, including military and commercial aircraft, military communications systems, oil and gas equipment, off-road vehicles, robotics and machine tools, and industrial equipment.

These compact and lightweight circular connectors support power, signal, and combined power and signal layouts to reduce system complexity and minimize component and installation costs and have aluminum alloy shells with a quick-disconnect bayonet coupling system that features high-strength aluminum coupling rings, rugged stainless steel bayonet pins, and a one-third-turn coupling mechanism that eases and hastens installation and provides both audible and tactile confirmation of proper mating.

They also have molded elastomer insulators that are bonded into the shells and designed to accommodate 2–61 copper alloy contacts with gold or tin-over-nickel plating and either integrated elastomer grommets for crimp contact variants or accessory elastomer grommets for solder contact variants. Additional options include a wide range of body styles, back fittings, terminations, and plating materials, IP and hermetic seals, solder and thermocouple crimp contacts, and keying and polarization features.

The series is designed to withstand climatic ingress and exposure to salt spray and corrosive atmospheres for 500 hours, is rated for 500 mating cycles and operating temperatures extending from -55°C to +125°C, is compliant with RoHS, REACH, and UL94 HB standards, and conforms to MIL-DTL-26482G Series I, NFC 93422, HE 301B, VG 95328, and GAM/T1 international standards. Air Electro maintains a large inventory of the various series components and can build the full breadth within 48 hours.
