FAQs
The 85100AC2039SX50 is designed as a square flange receptacle with a straight adaptor and X orientation, aligning with Souriau 851 series interfaces. It supports 39 solder-cup contacts within a 53 mm depth and a 36.9 mm width/height, enabling straightforward retrofit and consistent mating envelopes in existing panels and harnesses. Compatibility is enhanced by the same bayonet coupling approach and aluminium shell geometry that many Souriau 851 fixtures use in rugged environments.
Key specs include 39 contacts in a 53 mm long housing, 36.9 mm height and width, 58 g weight, aluminium shell, cadmium plating, 1/3 bayonet coupling, and solder cup contact type. The operating temperature range is -40 °C to 125 °C, and the connector is designed as a square flange receptacle with a straight backshell. These factors collectively support reliable signal and power transmission under harsh conditions.
Yes. The Eaton 85100AC2039SX50 is MIL-DTL-26482 SI qualified, indicating compatibility with stringent military-standard interfaces and high-reliability mating under demanding conditions. It also adheres to REACH environmental standards, ensuring restricted substances are managed in accordance with European regulations. This combination supports aerospace/defense applications and supply-chain compliance requirements.
Key considerations include the straight backshell geometry, adaptor type, and X orientation to match existing panel cutouts and mating interfaces. The connector is delivered with the connector, simplifying initial wiring, and the 1/3 bayonet coupling provides secure retention. plan for a 53 mm depth enclosure and the 39-contact harness when routing cables in dense panels.
Industries with tight space, high reliability, and rugged operating conditions benefit most, including defense, aerospace, and industrial automation. The 85100AC2039SX50 supports high-contact-count signaling with robust corrosion resistance, wide temperature tolerance, and qualified MIL-DTL-26482 interfaces, making it suitable for military vehicles, avionics harnesses, and mission-critical control systems where downtime must be minimized.
