General Information

Overview
EN 3155-075:2022 is a CEN/ASD-STAN product standard for aerospace electrical contacts - specifically shielded quadrax female contacts, size 8, Type E, crimp, class R. It defines the required characteristics, materials, marking, tooling and test requirements for quadrax socket contacts with a characteristic impedance of 100 Ω intended for use in connector elements per EN 3155-002. Class R denotes an operating temperature range of −65 °C to +150 °C. The standard supersedes EN 3155-075:2009 and is to be used together with EN 3155-001 (technical specification).
Key topics and technical requirements
- Contact type & performance: Quadrax, shielded, size 8 female (Type E), crimp termination; characteristic impedance 100 Ω, high-frequency performance and screening feature.
- Materials & plating: Copper-alloy body, gold plating with appropriate undercoat, and PTFE or equivalent dielectric.
- Physical limits: Maximum contact mass 6 g; dimensional drawings, tolerances and gauge requirements are specified.
- Environmental & electrical tests: Conformance testing referenced to EN 2591 series including:
- Contact resistance, insulation resistance (≥ 5 000 MΩ ambient; ≥ 1 000 MΩ at max temperature)
- Voltage proof, continuity, leakage current limits
- RF metrics: VSWR, insertion loss, characteristic impedance measurement and shielding effectiveness (e.g., surface transfer impedance ≤ 1 mΩ at 100 MHz; shielding 100 MHz–1 GHz)
- Mechanical & environmental: thermal endurance (1 000 h at 150 °C), rapid temperature change, shock, vibration, salt mist, fluid resistance and mechanical endurance
- Wiring & assembly: Cable compatibility (EN 3375 series - Star Quad types KD/KL/KH), crimping sequence, ferrule dimensions, and use of specified crimp tooling (e.g., M22520 positioners/dies; extraction tool M81969/14-06).
- Marking & identification: Manufacturer ID and date code (year-week) on contact body; pin-location orientation keys defined.
Applications and who uses it
- Aerospace connector manufacturers specifying or producing quadrax socket contacts for aircraft and spacecraft wiring harnesses.
- Harness fabricators and installers using crimp tools for reliable high-speed data pair terminations.
- Systems and avionics designers selecting shielded, impedance-controlled contacts for digital data transmission (100 Ω).
- Qualification and test labs performing EN 2591 series tests and environmental qualification per EN 3155-075.
- Procurement and quality engineers ensuring supplier compliance to CEN/ASD-STAN product requirements.
Related standards
- EN 3155-001 (Technical specification)
- EN 3155-002 (List and utilization of contacts)
- EN 3155-074 (Associated male quadrax contact)
- EN 2591 (Aerospace test methods)
- EN 3375-008 / -011 / -012 (Star Quad cables)
- EN 3645-001, EN 3909, EN 4008-003
