FAQs
The 85100A2027PX50 uses a MIL-DTL-26482 SI qualified square flange receptacle design with a 27-contact solder cup interface, matching Souriau 851 series conventions. It supports straight backshell adaptor configurations and X-oriented connector orientation, ensuring straightforward mating with compatible MIL-DTL-26482 components in aerospace and industrial automation assemblies.
Install with the straight backshell adaptor and ensure correct X orientation for mating. The connector delivers with a preloaded contact set and utilizes a 1/3 bayonet coupling for quick, secure engagement. With a 44 mm depth and 36.9 mm width/height, plan enclosure cutouts accordingly to minimize misalignment and streamline field assembly.
Key specs include operating temperature from -40 °C to 125 °C, cadmium plating for corrosion resistance, aluminium shell for lightweight strength, 27 contacts in a square flange footprint, and REACH environmental compliance. These features support reliability under vibration, wide ambient conditions, and regulatory alignment for aerospace and heavy industry applications.
Yes, the configuration is delivered with the connector option, featuring a straight backshell adaptor and X-oriented alignment. It ships loaded with 27 solder cup contacts and supports a 1/3 bayonet coupling for rapid field mating, making it suitable for modular panel assemblies and retrofit projects within the Souriau 851 family.
Reliability is enhanced by MIL-DTL-26482 SI qualification and cadmium plating, delivering corrosion resistance in harsh environments. The aluminium shell reduces weight without compromising strength, while the 1/3 bayonet coupling and high-density 27-position layout shorten assembly time and minimize downtime due to quicker mating. These factors translate to lower maintenance costs and improved system uptime.
