26 real samples of connector pins & machined pins, six categories, one shop
Each card is a genuine connector pin or machined pin sample we've produced — not a placeholder. Filter by category, check the material and process, and use it as a starting point for your own drawing.
Gold-Plated Signal Pin
Signal pins turned from brass and phosphor bronze for USB, HDMI and board-to-board interfaces, gold-flashed over nickel for low insertion force across 10,000+ mating cycles.
Right-Angle Connector Pin
Right-angle signal pins with integrated strain relief, gold-plated for board-edge and low-profile connector layouts.
Dual-Ended Contact
Symmetrical dual-entry contacts turned from brass with gold-over-nickel plating, engineered for interchangeable connector designs.
Edge Connector Pin
Beveled-tip edge connector pins gold-plated for card-edge interfaces, machined for smooth repeated insertion.
High-Speed Data Pin
Differential-pair data pins held to under 5 picoseconds of skew, gold-plated for high-speed signal integrity.
High-Current Contact Pin
Beryllium copper power contacts silver-plated for maximum conductivity, rated to 50A for EV battery and heavy power-connector applications.
Beryllium Copper Pin
Fatigue-resistant beryllium copper contacts rated for 50,000+ mating cycles, used across high-reliability connector applications.
Low-Resistance Power Pin
Silver-plated copper busbar pins turned for sub-0.1-milliohm resistance, built for high-current power distribution.
Precision Turned Connector
Passivated stainless connector pins for medical and industrial sensor housings, machined biocompatible and corrosion-proof for service to 300°C.
Spring-Loaded Contact
Spring-loaded contacts combining beryllium copper bodies with stainless springs, gold-over-nickel plated for reliable test-jig and charging contacts.
Test Probe Pin
Gold-plated test probe pins with a replaceable tip design, machined for ICT and FCT fixture longevity.
Pogo Pin Connector
Spring-loaded pogo pins rated to 100,000 cycles for magnetic charging and docking connectors, gold- or nickel-plated on request.
Precision Turned Contact
Smooth-finish precision contacts turned to sub-2-micron tolerance for high-speed data links requiring consistent impedance.
RF Coaxial Pin
Gold-plated RF pins turned to a 50-ohm impedance profile with low VSWR, machined for antenna and RF connector assemblies.
Micro Header Pin
Ultra-miniature header pins turned to sub-2-micron tolerance for wearables and micro connectors, gold-flashed for stable contact resistance.
Shielded Ground Pin
Shield-termination pins machined for EMI grounding paths, tin- or gold-plated to match connector shell requirements.
Miniature Terminal Pin
Compact tin-plated terminals turned from copper and brass for PCB and wire-to-board connections, sized for tight-pitch layouts.
Press-Fit Terminal
Compliant press-fit terminals machined for backplane assembly, tin-over-nickel plated to eliminate solder joints on high-density boards.
Gold Flash Terminal
Flat-face phosphor bronze terminals with flash gold plating, machined for reliable SMT solder-pad contact.
SMT Solder Pin
Through-hole and SMT solder pins tin-over-nickel plated and solderability-tested per batch, for consistent reflow performance.
Brass Machined Pin
Heavy machined brass pins with nickel plating and milled flats, built for high-strength connectors in industrial machinery.
Flanged Mount Pin
Flanged stainless pins passivated for panel-mount connectors, machined with a secure mounting shoulder for repeated field service.
High-Temp Alloy Pin
Inconel 718 pins machined for aerospace and turbine sensor applications, holding performance across an extreme -200°C to 700°C range.
Custom Threaded Pin
Threaded industrial pins machined to M2-M8 standard, zinc- or nickel-plated for corrosion resistance in heavy equipment.
Automotive Sensor Pin
Sealed stainless sensor pins gold-plated for TPMS and ABS systems, machined vibration-proof to IATF 16949 standards.
Heavy-Duty Industrial Pin
Oversized steel and brass pins for heavy equipment connectors, zinc- or nickel-plated to withstand high mechanical load and outdoor exposure.
