SIST EN 4652-002:2018

Overview

SIST EN 4652-002:2018 is a European Standard under the Aerospace series that specifies the performance requirements for coaxial radiofrequency connectors used in aircraft electrical systems. Published by CEN and developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN), this standard ensures uniformity and reliability in the design, manufacturing, and testing of these critical aerospace components. It forms part of a broader family of product standards that cover different connector types and configurations suitable for harsh aerospace environments.

Key Topics

• Scope and Purpose
  EN 4652-002 defines the list of applicable product standards and establishes common performance characteristics for coaxial RF connectors in aviation electrical systems.

• Product Standards
  The document references multiple related standards specifying various connector interfaces and configurations, including BNC, TNC, N, and C interfaces in clamp nut and crimp assembly versions across straight, right-angle, square flange, and bulkhead receptacles.

• Performance Requirements
  Key characteristics such as configuration, dimensions, mass, material, surface finish, and electrical properties are detailed in the individual product standards. The operating temperature range specified is from –65 °C to +165 °C to suit aerospace environmental conditions.

• General Technical Specifications

  • Tightening torque for connector caps must comply with the specific product standard.
  • Connectors are supplied with a protective plastic cap to safeguard contacts during storage and delivery.
  • Additional technical parameters like tool and stripping lengths, as well as admissible cable types, are formally defined and referenced per product standard.

• Normative References
  EN 4652-002 builds upon essential normative documents including EN 4652-001 which covers technical specifications applicable to all aerospace coaxial radiofrequency connectors.

Applications

• Aerospace Electrical Systems
  This standard is critical for manufacturers and aerospace system integrators designing and deploying electrical interfaces that require high-frequency coaxial connectors capable of reliable operation under demanding temperature and mechanical conditions.

• Aircraft Communication and Navigation
  Ensures interoperability and performance consistency of connectors used in radiofrequency signal transmission for avionics, radar, satellite communication, and telemetry systems.

• Quality Assurance and Compliance
  Provides a framework for the certification and testing of coaxial connectors, ensuring industry-wide compliance and facilitating global trade and supply chain integration within the European aerospace market.
