FAQs
The 85100E1832PW50 uses a square flange receptacle with a backnut, designed for straightforward panel mounting. It supports 32 solder-cup contacts, a straight backshell, and a W orientation, enabling consistent alignment across assemblies. This configuration is compatible with standard Souriau 851 series mating halves and simplifies harness routing in tight panel bays.
Key specs include a 32-contact layout with pin (male) contact delivery and solder-cup contact type. The shell is aluminium with cadmium plating, and the connector features a 1/3 bayonet coupling. The operating temperature range is -40 to 125 °C, and the overall depth and width are 32.7 mm and 33.7 mm, respectively, with a weight of about 34.6 g.
Yes. The aluminium shell with cadmium plating offers strong corrosion resistance, and the design is specified for broad temperature operation from -40 °C to 125 °C. The MIL-DTL-26482 SI qualification further ensures mechanical and environmental robustness, making it suitable for aerospace, defense, and demanding industrial environments where reliability is critical.
The primary certification is MIL-DTL-26482 SI qualification, which ensures MIL-spec performance and interoperability. Environmental considerations include REACH compliance. These factors collectively support aerospace, defense, and regulated industrial applications by meeting stringent performance and environmental criteria.
The backnut-equipped square flange with a 1/3 bayonet coupling streamlines mating and panel installation, while solder-cup contacts simplify field soldering and maintenance. With a 32-contact layout, this design reduces harness complexity and spare-part challenges, delivering quicker field upgrades, higher uptime, and overall lifecycle savings in panel-dense configurations.
