Explore our industry-standard surface mount, right-angle, custom bending, and magnetic interface spring contacts engineered for zero-failure electrical connectivity.
In modern microelectronics, establishing a highly reliable, low-wear electrical junction is crucial. Pogo contacts (spring-loaded pins) provide a highly effective solution compared to traditional leaf-spring and blade connectors. Their core design consists of three main components: a precision-turned plunger, a durable barrel, and a compressed internal spring. These elements ensure consistent contact force, low electrical impedance, and high tolerance to structural misalignments.
The modern electronics industry requires components to handle higher current densities and higher signal frequencies within smaller physical envelopes. Today's custom pogo pins are no longer simple mechanical structures. They are specialized components designed to minimize contact resistance, often down to less than 20 milliohms, and to maintain stable performance over hundreds of thousands of compression cycles.
As a leading manufacturer based in Shenzhen, China, we specialize in high-precision, custom pogo solutions. Our engineering team assists global clients through every stage of development, from initial mechanical layouts to high-volume Automated Optical Inspection (AOI) testing, ensuring compliance with strict industrial standards.
Located in Shenzhen, the leading technology hub of the Guangdong-Hong Kong-Macao Greater Bay Area, specializing in spring-loaded contact technology since 2011.
Our company was founded in February 2011 in Songgang Street, Shenzhen, focusing on the research, development, and manufacturing of POGO PIN connectors. Through continuous investment in precision engineering and high-volume automated manufacturing, we have become a reliable partner in the electronics industry. We specialize in design, manufacturing, and quality control for various custom spring contact models.
Our Vision: Committed to being an excellent POGO PIN manufacturer for both quality and cost in domestic and international markets, and leading the development of connector technology.
Operating under the principle of "customer first, integrity first", our engineering and production teams work closely with global clients. We have obtained ISO9001:2015 quality management certification, establishing strict quality systems and environmental controls to deliver components that meet high international performance standards.
We are a qualified supplier to major industry brands, including Honeywell, Samsung, SIEMENS AG, ZTE, 360, QCY, HAYLOU, Shanghai Laimu, Luxshare Group, Aoni Electronics, and Amphenol Group.
A statistical overview of our manufacturing capacity and quality compliance records.
Tracking the mechanical, materials-science, and structural evolution of spring-loaded contacts within next-generation hardware designs.
Environmental factors like human sweat and airborne moisture can corrode contact surfaces. Modern custom pogo pin plungers require specialized plating layers. Moving beyond standard gold plating, we now use Palladium-Nickel (Pd-Ni) and Platinum (Pt) alloys to improve corrosion resistance and reduce wear, making them suitable for high-exposure environments like sports wearables.
Fast-charging standards demand connectors that can carry high current densities. Standard pogo pins, restricted by internal spring materials, are generally limited to 1A or 2A. By optimizing internal plunger designs with specialized configurations (such as ball-point, bias-cut, or hollow plunger geometries), our pins can sustain high currents up to 15A without overheating.
As microelectronic devices become thinner, pitch spacing requirements continue to shrink. We manufacture micro-pogo contacts with a center-to-center pitch of just 0.4mm. These components are designed for high-density, multi-pin applications where space is limited but electrical performance must remain reliable.

How our automated facility in Shenzhen coordinates precision turning, high-speed assembly, and quality assurance workflows.
The quality of a pogo contact starts with precision turning. Our production floor uses high-precision CNC automatic lathes. Plungers and barrels are turned within micron tolerances (±0.005mm) to ensure smooth, low-wear movement and uniform contact resistance.
By shifting from manual assembly to custom automated production lines, we have scaled our capacity while reducing unit-to-unit variation. Our processes integrate inline spring force testing, internal barrel cleaning, and pin-alignment checks in one continuous automated flow.
Operating in Shenzhen gives us access to an established regional supply chain. We procure certified brass, copper, and stainless steel raw materials with minimal lead times. This regional integration enables us to keep lead times to just 7 to 15 days for standard production orders.
