Overview
EN 3646-002:2007 is a European standard published by CEN that specifies performance criteria and contact arrangements for aerospace electrical connectors. It focuses on circular bayonet coupling connectors designed for continuous operating temperatures of either 175 °C or 200 °C. These connectors are intended for use in extreme aerospace environments with temperatures ranging from -65 °C to 200 °C.
Derived from the MIL-C-26482 series 2 and intermateable with NAS 1599 connectors, this standard ensures high reliability and durability essential for aerospace electrical systems. It details the construction classes, materials, operating conditions, electrical and mechanical performance, and mating compatibility.
Key Topics
Connector Types and Classes:
Three main housing classes are covered:- A: Black anodized aluminum alloy, max 200 °C continuous operation
- RS: Nickel-plated aluminum alloy, max 200 °C continuous
- WS: Olive-green cadmium-plated alloy, corrosion resistant, max 175 °C continuous
Additional types include hermetic receptacles (Y) and protective covers and dummy receptacles matching these classes.
Operating Conditions:
- Wide temperature range from -65 °C to 175 °C or 200 °C continuously
- Electrical characteristics including insulation resistance above 5000 MΩ and voltage withstand ratings at different altitudes
- Mechanical endurance with minimum mating cycles (e.g., 250 to 500)
- Corrosion and fluid resistance following EN 3646-001
Contact Arrangements and Polarization:
Detailed housing sizes and a wide variety of contact arrangements, from 2 up to 61 contacts, are standardized. Polarization angles ensure proper alignment and prevent mismating. Contacts correspond to sizes 20, 16, and 12 with dedicated seating arrangements.Accessory Compatibility:
Specification includes filler plugs for unused cavities, rear accessories, protective covers, and tooling requirements for assembly, crimping, and wiring.Compliance and Intermateability:
Matches US MIL-C-26482 and NAS 1599 connector series in interface and performance, promoting global aerospace interoperability.
Applications
EN 3646-002 connectors are widely used in aerospace and defense electrical systems that demand high-performance connectors capable of withstanding harsh environmental conditions:
- Aircraft Electrical Wiring Harnesses: Ensuring reliable signal and power transmission in critical systems
- Spacecraft and Satellites: With extreme temperature fluctuations, hermetic connectors (Y type) prevent contamination
- Defense Equipment: Rugged designs resist shock, vibration, and corrosion
- Avionics and Control Systems: Precision contact arrangements support complex sensor and data networks
- Ground Support Equipment: Protective covers and dummy receptacles maintain system integrity during downtime
