Description

Our Precision Connector Contact Pins are custom-engineered conductive components designed specifically for your unique consumer electronics connector needs, leveraging advanced Turn-Mill Compound CNC machining technology. Crafted from premium Brass C3604 (or alternative materials upon request), these pins & sockets offer fully customizable specifications—including pin diameter (ranging from 0.8mm to 3.0mm), pin length (5mm to 50mm), socket inner diameter, and overall tolerance (as tight as ±0.003mm) to match your exact design requirements. The integrated turn-mill compound machining enables one-clamp completion of turning, drilling, chamfering, and step milling processes, minimizing clamping errors and ensuring exceptional dimensional consistency (≥99.9% even for custom mass production runs). Surface treatment options are also tailored to your application, including gold plating (0.5μm to 2μm), tin plating, or silver plating (with pre-plating precision polishing available for enhanced adhesion). Backed by excellent performance customization (rated current 3A to 20A, contact resistance ≤50mΩ, temperature resistance up to +150°C for special grades), our contact pins deliver stable conductivity and reliable durability. Ideal for automotive, smart home, and custom consumer electronics applications, we provide bespoke solutions that balance precision, efficiency, and cost-effectiveness, supported by full closed-loop CNC control to eliminate manual intervention errors. The below parameter table outlines our standard specifications, which can be fully adjusted to your project needs.
