Overview

The prEN 4165-025 standard is part of the Aerospace series focused on electrical rectangular modular connectors designed for continuous operation at 175 °C. Issued by CEN (European Committee for Standardization), this document specifically defines the single module receptacle-a critical component in high-temperature aerospace electrical systems. The receptacle supports various polarized modules (N, A, B, C, D) as specified in related standards, ensuring compatibility and interchangeability within aerospace connector families.

This product standard details the design, dimensions, materials, and mounting requirements, emphasizing reliability under harsh aerospace environments marked by elevated temperatures.

Key Topics

  • Single Module Receptacle Types

    • Type 0: Flange receptacle (short variant) with specified dimensions and keying options
    • Type 7: Jack receptacle (long variant/extender) offering additional rear accessory attachment
  • Materials and Class

    • Housing made of composite material with nickel plating for corrosion resistance
    • Designed for 500 hours salt mist resistance
    • Continuous operating temperature rating up to 175 °C
  • Panel Cut-Outs and Mounting

    • Detailed panel cut-out designs accommodate different polarizations and orientation options
    • Includes free mounting, orientation cut-outs, and polarized panel cut-outs for error-proof installation
  • Additional Parts and Accessories

    • Colour coding plates for easy module identification based on polarization
    • Nut plates and sealing gaskets to ensure secure assembly and environmental protection
    • Specification of materials such as stainless steel for nut plates and silicone elastomer for gaskets
  • Marking and Identification

    • Standards-compliant marking includes identity blocks, date codes, and manufacturer trademarks for traceability
  • Designations and Coding

    • A detailed system for designating receptacle variants and optional parts ensures clarity in product ordering and documentation

Applications

prEN 4165-025 connectors are ideal for aerospace and defense electrical systems requiring dependable, high-temperature rated modular rectangular connectors. These include:

  • Aircraft wiring harnesses and avionics equipment
  • High-reliability power and signal transmission in harsh environmental conditions
  • Aerospace platforms demanding salt mist resistance and consistent performance at high operating temperatures
  • Modular connector systems facilitating easy maintenance and upgrade with polarized module interchangeability

The standard’s comprehensive specifications support manufacturers and engineers in designing aerospace connectors that meet stringent safety, performance, and durability requirements.
