Overview
EN 3372-008:2007 is a European standard published by CEN that defines the product requirements for free plug connectors fitted with grounding springs within the aerospace series of electrical connectors. These connectors are circular, scoop-proof, and use bayonet coupling, designed to withstand continuous operating temperatures from -65 °C to 175 °C or 200 °C. Intended for medium to high contact density applications, this standard ensures interoperability, reliability, and safety for aerospace electrical systems. The standard forms part 008 of the EN 3372 series, which collectively covers the full family of compatible connectors, receptacles, covers, and accessories.
Key Topics
- Connector Type: Free plug with grounding spring, scoop-proof design.
- Coupling Mechanism: Bayonet ring coupling assures secure and quick connection.
- Operating Temperature Range: Reliable performance between -65 °C and up to 200 °C continuous.
- Material and Surface Treatment: Specifications for cadmium-plated or nickel-plated aluminium alloys to optimize corrosion resistance and durability.
- Dimensions and Mass: Detailed sizing to ensure compatibility, shown in metric units for various housing sizes and contact arrangements.
- Contact Types: Supports male (pin) and female (socket) contacts, delivered with or without contacts per EN 3155-002.
- Marking Requirements: Includes manufacturer identity, manufacture date (year and week), and product description codes.
Applications
EN 3372-008:2007 free plug connectors are critical components in aerospace electrical and electronic systems, offering robust and secure interconnections in harsh environments. Typical applications include:
- Aircraft electrical wiring harnesses requiring medium to high contact density.
- Systems exposed to extreme temperatures and environmental conditions demanding high reliability.
- Aerospace and defense industries where quick and scoop-proof connector mating reduces maintenance downtime.
- Installation in control systems, avionics, communication equipment, and power distribution interfaces.
These connectors ensure safe grounding through integrated grounding springs, preventing electromagnetic interference and enhancing system integrity.
