Overview
EN 4652-220:2017 is a European standard developed by CEN for the aerospace sector, focusing on the requirements for coaxial connectors - specifically straight plug, crimp version connectors with a TNC (Threaded Neill–Concelman) interface and 50 ohms impedance. These connectors are designed for lightweight coaxial cables and are optimized for reliable radio frequency (RF) performance, mechanical robustness, and appropriate environmental sealing.
This standard is vital for manufacturers, engineers, and quality assurance professionals in the aerospace industry who require reliable, standardized RF connectivity solutions for communication, control, and navigation systems.
Key Topics
- Connector Type: Specifies screwed-on TNC interface coaxial straight plugs, 50 Ω, crimp version.
- Application Cables: Suitable for a selection of lightweight coaxial cables, contributing to overall system weight reduction.
- RF Performance: Rated for 50 ohms impedance, supporting critical RF applications.
- Mechanical and Environmental Robustness: Includes detailed requirements for sealing, water ingress resistance, retention strength, and durability.
- Quality Assurance and Testing: Outlines test methods for electrical, mechanical, and environmental performance, referencing relevant aerospace standards.
- Marking and Traceability: Requirements for marking connectors in line with EN 2424 for product identification.
- Packaging and Storage: Guidance to ensure product integrity from production through deployment.
Applications
EN 4652-220:2017 is primarily used in:
- Aerospace Systems: Critical for connecting RF circuits in avionics, navigation, radar, and communication equipment where consistent performance and reliability are mandatory.
- Defense Equipment: Applied in military aircraft and ground systems needing robust and standardized coaxial RF connections.
- Lightweight Cabling Infrastructures: Supports lightweight cable assemblies, essential for modern aircraft weight management.
The connectors are engineered to comply with strict performance criteria-mechanical coupling, environmental sealing, high-frequency operation up to relevant GHz ranges-and guarantee operational integrity under the demanding conditions found in aerospace and defense industries.
