Feature → Business Impact → Application: MIL-DTL-26482 SI qualification ensures proven performance in extreme conditions, reducing warranty risk and field failures in aerospace and rugged industrial automation. This receptacle uses a backnut and straight backshell for secure panel mounting, delivering stable electrical connections in vibration-prone environments and simplifying installation in tight spaces. Cadmium plating on an aluminium shell provides corrosion resistance, extending service intervals in humid or saline atmospheres common to marine, offshore, or manufacturing facilities. The 1/3 bayonet coupling enables quick mating and demating, cutting assembly time by a measurable margin and improving first-pass wiring yields in high-density control panels. A 36-position Layout 36 with solder cup contacts supports dense harnesses, enabling scalable configurations and streamlined maintenance. Compatibility with Souriau 851 accessories reduces spare part variety and accelerates upgrades in legacy systems.

FAQs
Panel mounting requires a 40x40 mm opening with the backnut securing the square flange receptacle. Align the connector orientation to N and tighten per spec. Use the matching Souriau 851 series plug or mating half designed for 1/3 bayonet coupling to complete the pair. Ensure the mating surfaces stay clean to preserve seal integrity and environmental performance.
This receptacle features 36 solder-cup contacts in Layout 36 with pin (Male) contacts, cadmium plating, and an aluminium shell. It operates from -40 °C to 125 °C and complies with REACH. The backnut backshell facilitates secure mounting, and the connector is designed for MIL-DTL-26482 SI qualification with a 34.5 mm length and 40 mm square footprint.
Yes. It is MIL-DTL-26482 SI qualified, supports 1/3 bayonet coupling for fast mating, and uses cadmium plating on an aluminium shell for corrosion resistance. Its broad operating temperature range and 36-position layout support dense, reliable wiring in aerospace, defense, and rugged automation applications where vibration and exposure are common.
The primary certification is MIL-DTL-26482 SI qualification, indicating military-spec performance. Environmental compliance is reinforced by REACH. The design includes backnut mounting, a square flange receptacle configuration, and a cadmium finish, all contributing to corrosion resistance and long-term reliability in demanding environments.
Maintenance benefits come from robust mechanical retention, corrosion resistance, and a quick-lock 1/3 bayonet coupling that reduces field downtime. ROI is driven by high-density wiring, reduced spare parts through standard Souriau accessories, and longer service intervals enabled by durable cadmium-plated aluminium shells in harsh environments.
