Overview

EN 3155-028:2006 is a European standard issued by CEN that defines the product requirements for male electrical coaxial contacts used in aerospace applications. Specifically, it covers coaxial, shielded, size 16, type D, crimp, class R contacts designed for incorporation in elements of connection per EN 3155-002. This product standard ensures consistency, reliability, and performance of these critical electrical contact components utilized in aerospace electrical systems.

The standard must be applied in conjunction with EN 3155-001, which provides overarching technical specifications for electrical contacts, as well as related standards for female contacts (EN 3155-029 and EN 3155-039). EN 3155-028:2006 facilitates interoperability and quality control across aerospace manufacturers and suppliers.


Key Topics

  • Contact Type and Classification

    • Male coaxial electrical contacts
    • Size 16, type D, crimp termination
    • Shielded with class R rating (operating temperature range from –65 °C to +150 °C)
  • Material and Construction

    • Copper alloy for outer body, centre contact, and crimp ferrule
    • Gold surface treatment over appropriate undercoat
    • Dielectric made from PTFE or equivalent materials
