Pogo Pin 50kCycle Specifications

Time：2025-08-27 Views：1 source:

Pogo pins rated for 50,000 cycles (50kcycles) are engineered to maintain consistent performance through 50,000 insertion and extraction cycles, making them suitable for mid-range applications like medical device connectors, automotive sensors, and industrial control panels. These specifications define strict criteria for materials, dimensions, and performance to ensure reliability over the cycle count.

Material requirements often include a brass or stainless steel housing for structural integrity, paired with a phosphor bronze spring to withstand repeated compression. Contact surfaces are typically plated with 0.5–1μm of gold over a nickel underlayer, balancing conductivity, corrosion resistance, and wear resistance. The gold plating minimizes friction during cycling, while nickel provides a hard, adhesive base to prevent flaking.

Dimensional tolerances are tight: plunger diameter, housing length, and spring compression are controlled within ±0.01mm to ensure consistent mating forces (usually 50–200 grams) throughout the 50kcycles. This consistency prevents excessive wear or intermittent connections.

Performance standards include maintaining contact resistance below 50mΩ and spring force within 20% of initial values after 50,000 cycles. Environmental testing may also be specified, such as operation at -40°C to 85°C and 85% relative humidity, to validate performance in harsh conditions.

Manufacturers provide detailed test reports for 50kcycle pogo pins, including cycle test data, force-displacement curves, and corrosion resistance results, ensuring compliance with industry standards like IEC 60512 or customer-specific requirements.
