Our ball pogo pins (rolling ball-head spring-loaded connectors) are high-precision electrical contact solutions engineered for applications requiring multi-directional, sliding, or rotative connections. Unlike standard pointed or flat-tipped pins, these pogo pins feature a precision-embedded rotating ball at the tip. This allows the mating component to slide onto the contact from any lateral angle smoothly, minimizing friction and avoiding scratching or wearing down the mating plating.
They are widely used in advanced and dynamic electronic systems:
Rotary & Swivel Connectors: Perfect for 360-degree rotating slip rings, smart display mounts, and articulating robotic joints where continuous contact is required during movement.
Slide-In Charging Docks: Ideal for sliding-contact battery chargers, hand-held scanners, and docking stations where devices are pushed into place at an angle.
Magnetic Cable Connectors: Used in quick-attach magnetic power cables and data transfer ports to ensure zero-wear connections during frequent blind mating.
Precision Test Fixtures: Applied in automated testing interfaces where PCB boards slide across probe arrays, protecting delicate testing pads from scratches.
360-Degree Rolling Contact: The embedded rolling ball design reduces insertion force and lateral friction, ensuring smooth multi-angle sliding contact and eliminating surface wear on gold-plated PCBs.
Thick Gold Plating & Low Resistance: Featuring a multi-layer nickel underplate with high-thickness gold plating to guarantee low contact resistance (less than or equal to 30 mΩ) and exceptional wear resistance.
Wobble-Free Precision Fit: The spring barrel and ball retention cap are CNC-machined to micro-tolerances, keeping the ball securely in place while allowing it to roll completely freely without sticking.
Consistent Spring Pressure: Equipped with high-fatigue internal springs that provide stable and continuous contact force over 100,000 sliding-mating cycles.
Automated Assembly Compatibility: Designed with a precise stepped-body collar or flat flange, making them perfectly suited for automatic pick-and-place placement and reflow soldering.
We are an all-around direct source manufacturer with over 10 years of professional CNC machining and micro-precision metal component manufacturing experience.
Direct Factory Price Advantage: Source directly from our manufacturing workshop to eliminate trading margins and maximize your procurement cost efficiency.
All-Around Hardware Processing: As an all-around metal fabrication factory, we are highly experienced in processing diverse high-conductivity and high-hardness metals, including brass, phosphor bronze, beryllium copper, and stainless steel.
Bespoke OEM/ODM Customization: We customize micro-connectors to match your exact CAD/3D drawings. You can customize ball diameters, overall heights, stroke lengths, spring force, and gold-plating thickness.
Advanced Micro-CNC Swiss Lathes: Our facility is equipped with state-of-the-art Swiss-type automatic CNC lathes and high-precision assembly equipment to guarantee ultra-tight dimensional accuracy (up to +/-0.005 mm) and perfect ball seat concentricity.
Strict Quality Inspection: Every production batch undergoes rigorous ball-retention tests, rolling smoothly checks, spring tension testing, contact resistance measurement, and gold plating thickness analysis (XRF).
