Overview
FprEN 3545-005 (CEN) is a product standard in the EN 3545 aerospace connector series that defines the female coding and attachment system intended for mounting on free housings (plugs) of rectangular electrical connectors. It applies to connectors with sealed and non-sealed rears, plastic housings and locking devices rated for operation from –55 °C to 175 °C. The document updates material and designation rules (including introduction of zinc‑nickel plating) and sets dimensional, mass and fastening requirements for consistent interoperability in aerospace applications.
Key topics and technical requirements
- Scope: Female coding and attachment system for free housing (plug) within the EN 3545 family for aerospace rectangular electrical connectors.
- Operating temperatures: –55 °C to 175 °C.
- Dimensions & mass: Detailed geometry is given (see Figure 1 in the standard); maximum mass is 3 g.
- Materials & surface treatment:
- Body: steel, cadmium-plated with dichromate seal or zinc–nickel plated with trivalent passivation.
- Retaining ring: beryllium copper with same plating options.
- Washer and captive screw: cadmium-plated/dichromate or zinc–nickel with trivalent passivation.
- Mixing different surface treatments on a single attachment assembly is not allowed.
- Fastening & threads:
- Threads referenced to FED‑STD‑H28 (e.g., 0.1120 in‑40 UNC).
- Tightening torque for the locking screw: 0.06 daN·m to 0.10 daN·m.
- Design & performance: Main general characteristics are referenced to EN 3545-002; technical specification and designation follow EN 3545-001.
Applications and who uses this standard
- Aerospace OEMs and system integrators specifying reliable, standardized rectangular electrical connectors for airframes, avionics and onboard electrical systems.
- Connector manufacturers and suppliers designing female coding, attachment hardware and mating plug components to ensure interchangeability and compliance.
- Harness and installation engineers responsible for selection, mounting and torqueing of connector attachments under extreme temperature and vibration conditions.
- Maintenance, repair and overhaul (MRO) organizations verifying replacement parts and ensuring correct surface treatments and mounting practices.
Practical uses include connector procurement specifications, design validation, part marking/identification, and ensuring corrosion resistance and mechanical retention in harsh aerospace environments.
