Overview

EN 4652-221:2017 is a CEN aerospace product standard that defines the characteristics and test requirements for 50 Ω TNC interface coaxial right-angle plugs using crimp assembly technology. It applies to screwed-on coupling (TNC) coaxial RF connectors intended for aerospace use and specifies mechanical, electrical, material and environmental requirements for cable-to-connector assemblies.

Keywords: EN 4652-221, TNC interface, crimp right angle plug, aerospace connectors, 50 ohm, coaxial RF connectors

Key topics and requirements

• Scope & configuration

  • Right-angle plug, TNC (screwed coupling), crimp assembly; 50 Ω characteristic impedance.
  • Interface styles conform to EN 4652-001 (manufacturer declares style).

• Electrical

  • Characteristic impedance: 50 Ω ±5% (measured at 200 MHz).
  • Maximum operating frequency: 6 GHz.
  • VSWR limits: ≤1.15 at 150 MHz, ≤1.20 at 1 GHz, ≤1.35 at 6 GHz.
  • Insertion loss: 0.1 · f dB max (f in GHz).
  • Contact resistance (initial central contact): ≤1.5 mΩ.
  • Insulation resistance: ≥5 000 MΩ.
  • Voltage rating: 1 000 V rms.

• Mechanical & materials

  • Center contact: copper alloy, gold plated over nickel; insulators PTFE; seals silicone rubber or fluorinated material; heat shrink: polyolefin.
  • Operating temperature: –65 °C to 135 °C (polyolefin limited).
  • Tightening torque (coupling nut): 2.6 ± 0.3 Nm.
  • Service life: 500 mating cycles.
  • Centre contact retention: ≥27 N; cable retention examples: WM = ≥140 N.

• Environmental & tests

  • Mandatory tests include visual/dimensional checks, RF performance (VSWR, insertion loss, leakage), corona, salt mist, vibration, shock, temperature cycling, sand/dust, water ingress (mated for all cable groups; unmated required for cable group A), and crimp tensile tests.
  • Quality assurance per EN 9133.

Applications and users

• Intended for avionics, satellite, airborne radio and RF systems where robust, high-reliability coaxial RF connections are required.
• Typical users:
  • Aerospace component designers and engineers specifying RF interconnects.
  • Procurement and supply chain teams selecting qualified connector parts.
  • Cable assembly manufacturers using crimp tooling and cable codes (see TR 6058).
  • Test labs verifying performance to aerospace environmental and RF test regimes.
  • Quality and compliance teams ensuring parts meet EN 4652 series requirements.

Related standards

• EN 4652-001 - Technical specification for coaxial RF connectors (interfaces and designation).
• EN 4652-222 - Matched receptacle product standard (square flange).
• EN 2591 - Aerospace test methods (electrical/optical connection tests).
• EN 2812 - Cable stripping procedures.
• EN 9133 - Quality management / qualification for aerospace standard products.
• TR 6058 - Cable code identification list.

Practical takeaway: EN 4652-221 standardizes a 50 Ω TNC crimp right-angle plug for demanding aerospace environments, providing explicit electrical, mechanical, material and environmental test criteria to ensure reliable RF performance in flight and space applications.
