EN 4165-025:2017

• Abstract:

  This European Standard defines the single module receptacle used in the family of rectangular electrical connectors. The plug corresponding to this receptacle is defined in EN 4165-024. Accessories and protective cover corresponding to those plugs are defined in EN 4165-026. The cavity of this connector is uncoded, so it can accept polarized modules N, A, B, C and D as defined in EN 4165-002.

Overview

EN 4165-025:2017 is a CEN product standard in the EN 4165 aerospace series that defines the single module receptacle for rectangular, modular electrical connectors rated for 175 °C continuous operation. It covers physical dimensions, mounting and panel cut-outs, accessory interfaces and marking conventions for single-module receptacles used in high-temperature aerospace electrical systems. The corresponding plug is specified in EN 4165-024 and related accessories/protective covers in EN 4165-026.

Key topics and technical requirements

• Connector family & temperature: Part of the EN 4165 series for rectangular modular connectors designed for continuous operation up to 175 °C.
• Module compatibility: Uncoded cavity accepts polarized modules (for example N, A, B, C, D) as referenced in EN 4165-002.
• Design variants:
  • Type 0 - short (flange) receptacle; mass ≤ 6 g.
  • Type 7 - long (extender/jack) receptacle; mass ≤ 7.5 g.
• Class M housing: Nickel-plated composite shell with 500 h salt mist resistance and max operating temperature 175 °C.
• Accessories & materials:
  • Colour coding plate (Type C) - aids polarization identification.
  • Nut plate (Type D) - stainless steel.
  • Sealing gasket (Type E) - silicone elastomer.
• Panel cut-outs & mounting: Standardized free, oriented and polarized panel cut-out patterns and a mounting example are provided to ensure interchangeability.
• Marking & designation: Marking per EN 2424 (category P); formal designation format shown (e.g., EN4165 M 7 1 A N …).
• Normative references: EN 4165-001 (technical specification), EN 4165-002 (contact arrangements), EN 4165-018, EN 4165-024, EN 4165-026.

Applications

• Aircraft and spacecraft wiring harnesses and avionics requiring high-temperature, compact rectangular modules.
• Environmental and engine bay installations where continuous 175 °C performance and salt-mist resistance are required.
• Use cases requiring standardized panel cut-outs, keyed polarization and optional sealing for moisture protection.

Who should use this standard

• Aerospace electrical/mechanical design engineers specifying connector interfaces.
• Connector manufacturers and suppliers producing EN 4165-series receptacles and accessories.
• Procurement and quality teams verifying part conformity.
• Maintenance, repair and overhaul (MRO) teams ensuring correct replacement parts and mounting.
• Certification and compliance specialists referencing standardized connector definitions.
