FAQs
installation involves aligning the connector housing with the mate, engaging the 1/3 bayonet lugs to lock, and securing the square flange to the panel per standard Souriau mounting patterns. The adaptor backshell and straight orientation simplify routing, while cadmium plating improves corrosion resistance in harsh environments. Ensure the mating surfaces are clean and torque specifications from the enclosure design are followed to maintain EMI integrity.
The connector provides 41 solder cup contacts configured as male pins, with a 41-position layout and 53 mm length. It supports operating temperatures from -40 °C to 125 °C and uses a cadmium-plated aluminium shell for durability. The backshell is adaptor type with a straight angle, and the contact delivery is loaded for immediate assembly.
Yes. The MIL-DTL-26482 SI qualification, alongside aluminium shell, cadmium plating, and a wide temperature range, makes it well-suited for aerospace, defense, and rugged industrial applications. The 41-contact configuration provides high density without compromising robustness, and the 1/3 bayonet coupling offers reliable mating under vibration. REACH compliance further supports regulatory alignment in many regions.
This connector is MIL-DTL-26482 SI qualified, ensuring compliance with naval/military interconnect standards. It is REACH compliant, supporting safe chemical usage and environmental stewardship. The cadmium plating provides corrosion resistance in challenging environments, while the aluminium shell delivers light weight with mechanical strength suitable for high-vibration applications.
The 85100AC2041PW50 offers high-density interconnects with reliable mating, reducing harness complexity and installation time. Its durable cadmium plating and aluminium shell lower corrosion-related failures, while the bayonet coupling speeds field assembly and reduces maintenance downtime. Over a production cycle, these factors translate to lower spare-part costs and improved uptime, delivering a favorable total cost of ownership for OEMs and systems integrators.
