FAQs
To install, align the X orientation, engage the 1/3 bayonet coupling with the straight backshell adaptor, and push until the bayonet lugs lock. The unit ships with contacts loaded and connector pre‑assembled, which reduces assembly steps and ensures a reliable, field-ready mating sequence. Verify environmental and height clearances before finalizing mounting.
Key specs include eight solder cup contacts in a square flange receptacle with a cadmium-plated aluminium shell (size 8), straight backshell, 41 mm length, 21 mm width, 21 mm height, and a weight of 9.7 g. Operating temperature ranges from -40 °C to 125 °C, with REACH environmental compliance and MIL-DTL-26482 SI qualification.
Yes. The 85100A82SX50 is MIL-DTL-26482 SI qualified, a standard widely used in aerospace and defense programs for reliable interconnectivity. Its aluminium shell, cadmium plating, and rugged bayonet coupling are designed to withstand vibration, temperature variation, and harsh operating conditions typical of these industries.
The primary certification is MIL-DTL-26482 SI qualification, ensuring MIL-spec interoperability. The product is REACH compliant, demonstrating regulatory adherence for environmental safety. The design also emphasizes durability with cadmium plating and aluminium construction suitable for demanding environments.
The MIL-spec qualification and quick mating bayonet coupling minimize downtime during installation and field maintenance, improving throughput and uptime. Cadmium plating and aluminium shell offer robust corrosion resistance, which lowers replacement frequency. However, cadmium handling requires compliance with applicable environmental and safety guidelines.
