Overview
EN 3155-042:2006 is a CEN/AECMA product standard for aerospace triaxial electrical contacts - specifically male triaxial contacts 042, size 08, type D, solder, class P. It defines required characteristics, materials, dimensional limits, protection and performance tests for these connector pins used in aerospace elements of connection. The standard is to be used together with EN 3155-001 and EN 3155-002 (contact lists/utilization); associated female contacts are in EN 3155-043. These parts are derived from and interchangeable with legacy US/SAE references (MIL C 39029/96 / AS 39029/96).
Key topics and technical requirements
- Contact type and class
- Type D: triaxial design with screening feature.
- Class P: operating temperature range −65 °C to +125 °C.
- Mechanical and dimensional
- Size: 08, male contact code 042.
- Total mass: ≤ 3.90 g (after treatment).
- Detailed dimensions and gauges are specified (figures and table references in the standard).
- Materials and plating
- Contact bodies: copper alloy.
- Surface protection: gold on suitable undercoat (selective plating permitted); thickness recorded per test requirements.
- Cabling and termination
- Permitted cables: single braid, double braid, and high-immunity bifilar cables per EN 3375-003/004/005.
- Termination: solder type; tooling per MIL‑I‑81969 and EN 4008-002. Extraction tool: M81969/14-06.
- Electrical and environmental tests
- Contact resistance limits defined for centre and intermediate conductors (e.g., ≤15 mΩ initial, ≤30 mΩ after tests), and rated-current resistance conditions specified.
- Insulation resistance: ~5 GΩ at room temp, ~2 GΩ at high temp.
- Voltage proof: 500 V r.m.s. at sea level, 125 V r.m.s. at 4.7 kPa (altitude).
- Mechanical/environmental: shock, vibration, rapid temperature change, salt mist, fluid resistance, endurance. Signal discontinuity limits (≤100 ns) during shock/vibration.
- Tests referenced to EN 2591 series (test methods).
Applications and who uses this standard
- Aerospace connector manufacturers designing or producing triaxial male solder contacts for avionics and signal transmission.
- System and harness designers specifying reliable screened signal connections for EMI-sensitive equipment.
- Quality, test and procurement engineers verifying conformance to required contact resistance, insulation and mechanical performance.
- Maintenance and reliability engineers ensuring replacement parts are interchangeable with MIL/AS legacy components.
