FAQs

This square flange receptacle uses a backnut backshell and straight orientation to simplify panel mounting. Expect a standard panel cutout, and ensure the W orientation aligns with the mating connector. The unit is delivered with the connector assembled, reducing field work, and supports 30 solder-cup contacts for dense harness routing.
With 30 solder-cup contacts, the 85100E1830SW50 supports multiple circuits within a compact footprint. Proper crimping/soldering procedures and kept first‑mate alignment minimize crosstalk and impedance variations. This design is ideal for aerospace and automation panels where dense wiring and reliable continuity are required.
Yes. It is MIL-DTL-26482 SI qualified and rated for -40 °C to 125 °C, providing resilience against vibration and thermal cycling. REACH compliance further assures environmental responsibility. Cadmium plating contributes to corrosion resistance in harsh environments typical of aerospace and defense applications.
Absolutely. The MIL-DTL-26482 standard enables compatibility across the Souriau 851 family, allowing backnut, backshell, and mating connector variations to be swapped with minimal redesigns. This supports fleet standardization and easier procurement across multiple platforms.
The combination of MIL-DTL-26482 SI qualification, 30 solder‑cup contacts, and backnut design reduces field maintenance time, enhances reliability in extreme conditions, and lowers inventory complexity by standardizing on a single high‑performance receptacle. Over the lifecycle, this translates to lower downtime, fewer spares, and smoother regulatory compliance.
