FAQs
This square flange receptacle uses a 1/3 bayonet coupling and straight backshell adaptor, compatible with Souriau 851-series mating inserts. Orientation is set to N, and it ships Delivered with connector for quick field assembly.
Key specs include 27 contacts, solder cup termination, aluminum shell with cadmium plating, 53 mm length, 36.9 mm width and height, weight about 49.8 g, operating range -40 °C to 125 °C, and square flange receptacle configuration. In addition, it is REACH compliant.
Yes. It is MIL-DTL-26482 SI qualified, uses an aluminum shell with cadmium plating for durability, and is REACH compliant, making it suitable for aviation, defense, and harsh industrial deployments that demand reliability and regulatory alignment.
The 27-contact arrangement maximizes signal density within a compact 53 mm by 36.9 mm footprint, enabling robust multi-signal interconnects without enlarging the panel. This eases harness routing, reduces panel real estate, and supports higher system integration density.
The combination of quick mating via 1/3 bayonet coupling, corrosion protection (cadmium plating on aluminum), and a durable backshell adaptor reduces maintenance downtime and replacement costs. Its MIL-spec qualification helps ensure long-term availability and predictable lifecycle costs in regulated programs.
