Overview

EN 3660-005:2023 - "Aerospace series - Cable outlet, style A, 90°, unsealed with clamp strain relief - Product standard" - specifies product requirements for a family of 90° cable outlets (style A) used with circular and rectangular electrical and optical connectors in aerospace applications. The standard defines dimensional data, materials/finishes, mechanical and electrical characteristics, assembly and coupling torques, and qualification/test requirements for different material classes and temperature ratings. It is intended to be used with the associated connector specification EN 3660-002 and the technical specification EN 3660-001.

Key topics and technical requirements

• Scope & compatibility
  • Associated electrical connector(s): EN 3660-002.
  • Applies to unsealed 90° cable outlets with clamp strain relief (style A).
• Temperature classes
  • Class N: −65 °C to 200 °C
  • Class W: −65 °C to 175 °C
  • Class K: −65 °C to 260 °C
  • Class A: −65 °C to 260 °C
  • Class T: −65 °C to 175 °C (nickel PTFE plating)
  • Class Z: −65 °C to 175 °C (black zinc nickel plating)
• Dimensions and interface
  • Detailed shell sizes, thread types and interface dimensions are specified (see Figure 1, Table 1 and Table 2 in the standard). Wire accommodation sizes, tooth counts and front interface dimensions are standardized for interchangeability.
• Materials and finishes
  • Specified by class (e.g., aluminium with electroless nickel, olive drab cadmium, stainless steel/passivated, black anodized, nickel PTFE, black zinc nickel).
• Mechanical & electrical limits
  • Assembly torques, coupling thread strength torques (for test), and electrical continuity limits (e.g., Classes W, N, A, T, Z: ≤ 5 mΩ; Class K: ≤ 10 mΩ measured from mounting flange to clamp end).
• Testing and qualification
  • Refers to EN 2591 test methods and EN 3660-001 for qualification. Includes vibration, shock, temperature cycling, salt mist (varying durations by class), mechanical strength (bending moment), magnetic permeability, and other environmental tests.

Practical applications and users

• Typical use: rear-end cable outlet accessories for aerospace electrical and optical connectors where a 90° unsealed clamp strain relief is required.
• Primary users:
  • Aerospace connector designers and manufacturers
  • Electrical harness and cable assembly engineers
  • Procurement specialists specifying connector accessories
  • Test laboratories performing connector qualification and environmental testing
  • Systems integrators and maintenance engineers ensuring component interchangeability and traceability
• Benefits: ensures mechanical compatibility, environmental robustness, consistent material/finish selection, and defined test criteria for high-reliability aerospace installations.
