Overview

EN 3155-034:2007 is a CEN product standard in the Aerospace series that specifies requirements, tests and tooling for male triaxial electrical contacts, size 08, type D, crimp, class R. It applies to contacts used in elements of connection per EN 3155-002 and is intended to be used together with EN 3155-001 (technical specification). These contacts are designed for high‑reliability aerospace and defence applications where a screened (triaxial) contact is required and an operating temperature range of −65 °C to +150 °C (class R) is needed.

Key Topics

  • Contact type and scope
    • Male, triaxial contacts, size 08, type D, crimp termination, class R.
    • Interchangeable with MIL‑C‑39029/96 and EN 3155‑042.
  • Materials and construction
    • Contact bodies, center and intermediate contacts, and crimp ferrules: copper alloys.
    • Dielectric: PTFE. Surface plating: gold over suitable undercoat (selective protection permitted).
    • Maximum mass: 5.2 g.
  • Electrical and environmental requirements
    • Insulation resistance: ≥ 5 000 MΩ at ambient, ≥ 2 000 MΩ at maximum temperature.
    • Withstand voltage at sea level: 1 000 V r.m.s. (centre ↔ intermediate), 500 V r.m.s. (intermediate ↔ outer). Altitude test: 125 V r.m.s. at 4.7 kPa.
    • Contact discontinuity: ≤ 100 ns during vibration/shock tests.
  • Mechanical and crimping
    • Crimping tooling per MIL‑DTL‑22520; insertion/extraction tooling per MIL‑I‑81969/14.
    • Typical crimp length specified (example: 6 mm for outer braid crimp).
    • Minimum tensile values for crimped connections: centre/intermediate 36 N, outer 113 N.
  • Qualification and tests
    • Test regime references EN 2591 series and EN 3155‑001 (visual, dimensional, contact resistance, endurance, thermal cycling, vibration, salt mist, fluid resistance, solderability, coating thickness/adhesion, magnetic permeability, etc.).

Applications

  • Designed for use in aerospace and defence connector systems requiring shielded/triaxial conductors (e.g., avionics, radio frequency subsystems, sensor cabling).
  • Intended for connector manufacturers, avionics engineers, procurement/specification teams, and test laboratories that require standardized, high‑reliability triaxial crimp contacts.
  • Useful where screening and EMI control are critical and where parts must be interchangeable with MIL and other aerospace standards.

Related Standards

  • EN 3155-001 (technical specification)
  • EN 3155-002 (list and utilization of contacts)
  • EN 3155-035 / EN 3155-043 (associated female triaxial contacts)
  • EN 3155-042 (solder type equivalent)
  • EN 2591 series (test methods)
  • MIL‑C‑39029/96, MIL‑DTL‑22520, MIL‑I‑81969/14, EN 3682-001, TR 6058

Keywords: EN 3155-034, triaxial contacts, aerospace electrical contacts, size 08, crimp contacts, type D, class R, connector contacts, aerospace standard.
