Overview

prEN 4165-027 defines the product standard for rack and panel rear mounted plugs for 2- and 4-module configurations in the Series 3 family of rectangular electrical connectors. Developed under ASD-STAN and submitted to CEN, this draft standard aligns with the Aerospace series requirement for an operating temperature of 175 °C continuous and references the corresponding receptacle specification in EN 4165-002.

The document sets out required characteristics, design classes, marking requirements and references the technical specification given in EN 4165-001.

Key Topics

  • Scope: Product standard for Series 3 rack and panel rear mounted plugs for 2 and 4 modules; receptacles covered by EN 4165-002.
  • Operating temperature: Rated for continuous operation at 175 °C.
  • Design figures: Plugs shall conform to the dimensions and layouts shown in the referenced figures for 2-module and 4-module configurations (Figure 1 and Figure 2).
  • Coupling torque: Screw coupling torque on panel is specified as 0.6 N·m ± 0.1 N·m.
  • Plug classes (Table 1):
    • Class W - Housing (shell) olive drab cadmium plated, aluminium alloy; 500 hours resistance to salt mist; max 175 °C continuous.
    • Class F - Housing (shell) black nickel plated, aluminium alloy; 96 hours resistance to salt mist; max 175 °C continuous.
  • Marking: Marking shall include the identity block per Clause 6, date of manufacture (year–week) and the manufacturer’s name or trademark.
  • Normative references: EN 4165-001 (technical specification) is normative for this part.

Applications

This part of EN 4165 targets designers, manufacturers and procurement specialists working on aerospace electrical systems that require modular rectangular connectors with high-temperature capability and proven corrosion resistance. Practical applications include:

  • Avionics racks and panel interfaces where compact, modular connector design is required.
  • Aerospace equipment subject to elevated operating temperatures (up to 175 °C continuous).
  • Systems requiring defined corrosion resistance and standardized marking for traceability.

Benefits for users include predictable mechanical interfaces, defined environmental durability classes (W/F), and alignment with the EN 4165 connector family for interchangeability and system integration.
