Maintain stable electrical connection without breakage at ± 10g, 3-axis, frequency 10-2000Hz, with interface holding force exceeding 30N. High vibration unmanned aerial vehicles, AGVs, and portable military equipment can use 2 pin waterproof connector.
Verification of working temperature range: Performance remains stable throughout the temperature range of -40℃ to +105℃.
Perform temperature change testing according to IEC and simulate morning and evening extreme temperature fluctuations. Low temperature without cracking, high temperature without melting corrosion. The entire contact impedance is normal, suitable for industrial/outdoor applications in wide temperate zones.
Plug and unplug lifespan testing: After more than 8,000 mechanical plug and unplug cycles, the function is complete and the impedance fluctuation does not exceed ± 5%.
According to EIA, test the reliability of pogo pins. After 8,000 insertions, the rebound consistency of the spring loaded pin is better than ± 0.02mm. It maintains stable contact pressure and meets high-frequency maintenance or module hot plugging requirements.
Contact resistance stability: below 50mΩ, with fluctuations not exceeding ± 3mΩ.
Tested under 5,000 cycles of insertion and removal and IP67 humid and hot alternating environment, the contact resistance remained stable at 20~30mΩ, far exceeding the industry’s typical threshold of 48mΩ, effectively avoiding micro arc risks and signal discontinuity issues.
Current endurance: The continuous working current passing capacity reaches 2.2A, the instantaneous carrying capacity is 3A, and the temperature rise is controlled within 15℃.
Under UL1977 load testing, the heat distribution in the current carrying path is uniform and the heat rise is low. The 2 pin waterproof connector has a heating temperature rise of no more than 15℃, making it suitable for synchronous transmission of signals and low to medium power.
Wear resistance of metal coating: Gold plating thickness ≥ 0.5μm, gold layer wear area <15% after 10,000 contacts.
Adopting 0.5μm thick Au (Gold) electroplating, the contact surface is corrosion-resistant and has excellent wear resistance. High end industrial control systems maintain electrical performance even after multiple plugging and salt spray tests, ensuring long-term reliability.
Size consistency control: Pogo pin positioning deviation <± 0.02mm, pitch deviation <± 0.01mm.
CMM batch testing ensures precise matching with the mother seat. Avoid insertion stress and poor contact caused by tolerance accumulation. Suitable for automatic assembly production lines.
