FAQs
When installing the Eaton Souriau 85100AC83SX50 in panel-mounted applications, use the square flange receptacle mounting with the 21 x 21 mm profile and 48 mm depth. The straight backshell adaptor and X orientation simplify alignment behind control panels. Ensure correct panel cutouts, tighten mounting hardware to spec, and verify the 3-contact, solder cup configuration aligns with the harness lead layout for optimal wire routing and strain relief.
MIL-DTL-26482 SI qualification confirms the connector meets stringent military-style performance requirements, including interface, seal, and durability criteria. The SI designation often relates to solder contact readiness and reliable insertion/extraction under vibration. For programs demanding traceability and rugged performance, this qualification provides confidence in long-term operability in harsh environments.
Yes. The 1/3 Bayonet coupling provides secure mating with fast engagement and disconnection, which is advantageous in vibration-intensive settings. The straight backshell adaptor supports stable alignment, while the aluminium shell and cadmium plating contribute to durability. These features together support efficient, reliable mating on automated lines and in field service scenarios where quick, repeatable connections are required.
The assembly uses three solder cup contacts within a three-cavity layout, delivered as a loaded receptacle. The aluminium shell (size 8) with cadmium plating supports robust electrical performance, while maintaining low contact resistance across -40 °C to 125 °C. Compatibility with standard soldering processes and a 3-contact arrangement enables straightforward harness integration in control panels and equipment.
The 851 series provides reliable MIL-DTL-26482-based interconnectivity with SI-qualified performance, long-term environmental tolerance (REACH), and a compact footprint suitable for tight installations. For aerospace and industrial automation, this translates to reduced maintenance, improved uptime, and regulatory alignment, delivering lower lifecycle costs while maintaining harness integrity under demanding operating conditions.
