FAQs
The 85100A128SZ50 uses a square flange receptacle with a straight adaptor and a 1/3 bayonet coupling. It features eight socket (female) solder cup contacts loaded in a single assembly, arranged to align with corresponding Souriau 851 series plugs. This design supports secure mating with quick disconnect capability, while maintaining reliable electrical performance in vibration-prone environments.
This receptacle is designed for compatibility within the Souriau 851 family, sharing the MIL-DTL-26482 interface and bayonet coupling approach. To ensure mating integrity, use a corresponding 851-series plug with the same backshell orientation (Z) and connector type (receptacle) and verify the contact count and shell size match your harness and panel cutout requirements.
Yes. The part is specified for operating temperatures from -40 °C to 125 °C and employs aluminium shell with cadmium plating, providing robust corrosion resistance. This makes it appropriate for aerospace, defense, and industrial automation applications where environmental exposure and temperature variation are significant design considerations.
Ensure proper PCB or harness soldering by using appropriate heat control, pre-cleaned contacts, and adequate heat sinking to prevent thermal damage. Since contacts are solder cup type and pre-loaded, follow standard MIL-spec soldering procedures, verify solder fillet integrity, and perform a post-solder inspection to confirm joint reliability under vibration and thermal cycling.
Choosing the 85100A128SZ50 delivers predictable reliability, prolonged service life due to corrosion resistance, and faster installation with pre-loaded contacts and a compact form factor. This translates into lower maintenance costs, reduced spare parts inventory for MIL-spec applications, and easier regulatory compliance (REACH) for equipment deployed in aerospace, defense, and industrial sectors.
