Component Specifications

Definition
Conductor pins are critical components in electrical feedthrough assemblies designed to maintain electrical continuity while passing through vacuum, pressure, or environmental barriers. These pins serve as the conductive interface between internal and external electrical circuits, engineered to prevent leakage, arcing, or contamination while withstanding specific operational conditions such as high voltage, temperature extremes, or corrosive environments.
Working Principle
Conductor pins operate by establishing a continuous electrical pathway through an insulating feedthrough body. The pin maintains electrical conductivity while being mechanically sealed within insulating materials (typically ceramics or glass) to prevent fluid/gas leakage and maintain dielectric isolation. Electrical current flows through the pin's conductive core while the insulation prevents short circuits and maintains system integrity.
Materials
Copper alloys (C10100, C11000), nickel alloys (Nickel 200, Inconel), stainless steel (304, 316), with optional gold or silver plating for enhanced conductivity and corrosion resistance. Insulation materials include alumina ceramics (Al2O3), glass (borosilicate), or high-performance polymers (PEEK, PTFE).

Frequently Asked Questions

What are the main failure modes of conductor pins in feedthrough applications?

Primary failure modes include insulation breakdown due to voltage stress, pin corrosion in aggressive environments, thermal expansion mismatch causing seal failure, and mechanical fatigue from vibration or thermal cycling.

How do I select the right conductor pin material for my application?

Material selection depends on conductivity requirements, environmental conditions (temperature, corrosion), mechanical strength needs, and compatibility with insulation materials. Copper alloys offer best conductivity, nickel alloys provide corrosion resistance, and stainless steel offers mechanical strength.

What testing is required for conductor pin quality assurance?

Standard testing includes helium leak testing for hermeticity, high-potential (hipot) testing for dielectric strength, resistance measurement, thermal cycling tests, and mechanical pull tests to verify seal integrity.
