Performance Test of 2 Pin Connectors
Actual measurement of contact resistance: Measure the point-to-point resistance of a single pin using the four wire method to ensure a low impedance connection of 10mΩ. High current, high-frequency transmission environment, reducing heat loss and signal interference.
Maximum continuous current carrying capacity: Apply a constant DC current of 30A at 25°C. Keep powered continuously for 8 hours without any abnormal temperature rise or material structure changes. 2 pin connectors are commonly used in high-power power supply/driver systems.
Single Pin Axial Compression Life: Repeatedly operated 10,000 times under standard compression stroke by a mechanical fatigue testing machine. The end-of-life standard is a decrease in elasticity of ≥30% or poor contact. Satisfy the long-term embedded applications of most customers.
Working range and stable contact force: Maintain a stable elastic force of 2.00 ± 0.3N within the effective working range of 1.60mm ±0.05mm. Avoid intermittent conduction due to insufficient contact force. High signal reliability during vibration or multi axis movement.
Corrosion resistance of metal surface: tested according to ASTM B117 standard, passed 48 hour salt spray test (gold plating thickness ≥5μm). Verify the material stability of 2 pin connectors for long-term use in sea freight, outdoor, and humid conditions.
Insulation withstand voltage test: AC 1000V/60s without breakdown or flashover. Ensure sufficient electrical isolation between different pogo pins and between pogo pins and the casing. To avoid high-voltage crossing, industrial electrical safety is very high.
Temperature rise test: Apply 30A current and stabilize within ΔT≤30℃. Record the temperature rise trend under a constant current of 30A using infrared thermography. Determine whether the heat dissipation capability meets the packaging design requirements.
Stability of vibration impact environment: Conduct 10Hz~2000Hz sine scan and 50g impact test respectively. Record changes in connection status in accordance with IEC 60068-2-6/2-27 standards. Applied to high vibration unmanned aerial vehicles, robotic arms, and high-speed equipment without contact failure.

Customization of 2 Pin Connectors
High current and high spacing: designed with a spacing of>8.00mm to avoid breakdown between pins. Stable power supply under high current path. Covering battery modules, industrial equipment sockets, high reliability testing fixtures, etc.
Multi condition mechanical stability: With a plug-in life of over 10,000 times, the elastic retention force of the mating surface can be adjusted from 3N to 8N. Ensure that the mechanical coupling strength and contact pressure drop are always within the set tolerance.
Stable control of connection resistance: The contact resistance is less than 50mΩ, and the maximum tolerance is controlled within ± 2mΩ. Strict signal and power are used together, and the system error is within the customer’s expected range.
Customer defined structure: Customize the plunger stroke according to client’s actual application, ranging from 0.8mm to 3.5mm. Housing fixed structure through plates, buckles, bolts, etc. Tail welding or crimping form (DIP/SMD/FPC crimping end).
High temperature and corrosion compatibility: The material supports a maximum working temperature of 260 ° C (continuous). To meet the requirements of high-temperature reflow soldering or exposed type, pogo pin coating provides multiple specifications of gold thickness ranging from 0.1 μm to 5 μm. Salt spray resistance test passed for more than 48 hours.
Transparent delivery at the process level: Each batch is equipped with 23 testing data (current, elasticity, insertion and extraction force, contact resistance, etc.) upon leaving the factory. We can provide 2D/3D/REACH/ROHS according to customer needs.
Modular development: supports rapid mold turnover and terminal structure design for demand of ≥1M months. Shorten project development cycle by more than 40% and support serial expansion under the same PIN structure.
Prototype rapid validation: Standard samples will be delivered within 3-5 days. Customers can complete mechanical and electrical rapid validation during the prototype phase to reduce iteration risks.
Cross team technical collaboration: collaborate with customer FAE/institution/EMC/thermal simulation teams. Provide modeling data packages: structural stacking suggestions and current paths. Adapt to different CAD/simulation environment standards.

FAQ
What is the maximum sustained current capacity of 2 pin connectors? Single pogo pin supports continuous current from 5A to 50A, and can accurately match the thermal and voltage drop tolerance of the customer’s system based on the pogo pin structure and coating thickness.
What is the acceptable range of connection resistance for 2 pin connectors? The typical value of contact resistance is controlled within 20 mΩ – 50 mΩ, with a tolerance of less than ± 2 mΩ. Under special requirements, Johoty can meet the high stability and high conductivity requirements of customers at 10 mΩ.
Can 2 pin connectors meet non-standard pitch and structural installation requirements?
