MIL-DTL-26482 SI qualified with a cadmium-plated aluminium shell ensures rugged, compliant performance in demanding environments. This translates to reduced rework and smoother qualification testing for aerospace and industrial programs. Applications include control panels, sensors, and I/O modules in harsh environments. Backshell options include a straight adaptor with 1/3 bayonet coupling for secure mating at panel depth, delivering quick, lockable connections and reliable vibration resistance. This is ideal for panel-mounted assemblies and field service in aircraft bays, rugged automation racks, and remote sensor housings. Contact delivery is loaded with two pin (male) solder-cup contacts across eight cavities (#20), enabling straightforward solder termination and stable signal paths. The arrangement supports efficient harness assembly and repeatable mating in high-mkil resistance environments common to defense and industrial control applications. The connector uses an aluminium shell (shell size 12) with a compact 41 mm length and a 26.5 mm width/height profile, weighing 16.7 g. This lightweight, small-footprint design helps minimize system weight and frees space in crowded enclosures, a frequent constraint in avionics and heavy machinery. Orientation is N, and the receptacle is a square flange type delivered with the connector, simplifying panel cutouts and ensuring correct mating orientation. These characteristics support rapid installation and consistent performance across multiple assemblies in automated facilities.

FAQs
The 85100A122P50 uses a square flange receptacle with a straight adaptor and 1/3 bayonet coupling, allowing quick, secure panel mating. It ships with two pin (male) solder-cup contacts across eight cavities, and features an N orientation to ensure correct alignment during installation. This design is compatible with MIL-DTL-26482 mating halves used in aerospace and industrial equipment.
Key specs include an aluminium shell (shell size 12), cadmium plating, 41 mm length, 26.5 mm height and width, 16.7 g weight, operating range -40 °C to 125 °C, 2 contacts, and 8 cavities (#20). Contact type is solder cup, with the backshell being an adaptor and a straight orientation. The device is a loaded Receptacle with a 1/3 bayonet coupling.
Yes. Operating from -40 °C to 125 °C, aluminium shell construction, and cadmium plating provide durability under harsh conditions. The MIL-DTL-26482 SI qualification further supports reliability in aerospace and defense programs, while the REACH environmental compliance helps ensure regulatory alignment for industrial installations. This makes it well-suited for avionics enclosures, rugged automation panels, and extreme-duty equipment.
This connector is MIL-DTL-26482 SI qualified, indicating military-grade interconnection performance. It also lists REACH compliance for environmental responsibility. While the data does not specify CE or IP ratings, MIL-DTL-26482 qualification and REACH provide strong evidence of suitability for aerospace and industrial applications requiring rigorous standards.
Plan for panel mounting using the square flange receptacle with a straight adaptor and N orientation to guarantee proper mating. Use the pin (Male) solder cup contacts loaded in eight cavities (#20) for straightforward solder termination. The 41 mm length, compact footprint, and 16.7 g weight minimize enclosure footprint and weight impact, while the 1/3 bayonet coupling supports fast, vibration-resistant mating in automation panels.
