Gold-Plated Spring Loaded Pogo Pin Connector

This spring loaded pogo pin is a precision elastic conductive connector designed for intermittent electrical contact testing and equipment signal docking. The entire brass body and contact tip undergo professional full gold electroplating process with nickel underlayer pre-treatment, which greatly enhances coating adhesion. The thick hard gold plating layer effectively resists oxidation, humidity corrosion and abrasion from thousands of repeated compression cycles, maintaining stable ultra-low contact resistance to avoid signal interruption during continuous testing and docking.

Built-in stainless steel spring provides consistent elastic pressure, ensuring tight contact even under slight assembly offset. Multi-size diameter and length options fit diverse equipment mounting holes. Ordinary bare copper or nickel-plated probes will oxidize rapidly in humid workshop environments and generate unstable contact resistance after frequent compression. We integrate precision CNC turning, spring assembly and gold electroplating as a complete production workflow. All metal components pass multi-stage cleaning and activation before plating to eliminate missing plating or coating peeling risks. After electroplating, every finished pogo pin undergoes 100% compression elasticity and electrical conductivity inspection to guarantee reliable matching with test fixtures and electronic modules. When customers adjust fixture layout dimensions, we only need to update CNC turning drawings and synchronize electroplating parameters to match new equipment iteration demands.
