Overview

FprEN 3545-006 is a CEN draft product standard in the Aerospace series that defines the male coding and attachment system for mounting on fixed housings (receptacles) in the family of rectangular electrical connectors. It applies to connectors with sealed and non-sealed rears, plastic housing and locking devices, designed for extreme operating temperatures from −55 °C to 175 °C. The document updates EN 3545-006:2015 and is prepared by ASD‑STAN/CEN.

Key Topics

• Scope: Male coding and attachment system for mounting on fixed housings (receptacles) within the EN 3545 connector family.
• Dimensions & mass: Detailed dimensional requirements are given (Figures 1–3) with tolerances in millimetres; maximum mass 6 g.
• Threading & fasteners: Thread sizes referenced to FED‑STD‑H28 (examples in the standard: Ø 0,1120 in‑40 UNC‑3B and Ø 0,2500 in‑28 UNF‑3A/3B).
• Materials & surface treatments:
  • Body: steel, cadmium‑plated with dichromate seal OR Zinc/Nickel plating with trivalent passivation.
  • Retaining ring: beryllium copper with same plating options.
  • Washer & nut: steel, same plating options.
  • Mixing different surface treatments on the same attachment system is not permitted.
• Mechanical characteristics: Main general characteristics refer to EN 3545‑002; specified panel mounting nut tightening torque 0.125–0.150 daN·m.
• Technical and designation rules: Cross‑references to EN 3545‑001 (technical specification) and EN 3545‑002 (performance and contact arrangements).

Applications

• Use for design, manufacture, procurement and verification of aerospace rectangular electrical connectors where a standardized male coding and attachment for receptacles is required.
• Relevant to connector manufacturers, aerospace OEMs, harness houses, system integrators, quality and certification teams, and test laboratories.
• Ensures interchangeability, reliable mechanical retention and corrosion‑resistant finishes for harsh environmental and temperature extremes (avionics, airframe systems, spacecraft interfaces).

Related Standards

• EN 3545‑001 - Technical specification for the connector family
• EN 3545‑002 - Specification of performance and contact arrangements
• FED‑STD‑H28 - Screw thread standards (referenced for thread forms)

FprEN 3545‑006 is essential for stakeholders who need to implement or verify compliant male coding and attachment systems within the EN 3545 connector family, supporting consistent performance, corrosion protection (zinc‑nickel or cadmium finishes) and mechanical compatibility across aerospace applications.
