Performance Test of 8 Pin Connectors
Contact resistance consistency testing: Refer to IEC to apply 250g standard contact pressure to 8 pins respectively. The contact resistance of each pogo pin was measured to be 18.2-19.1mΩ under constant current 1A condition. The maximum deviation is less than 0.9mΩ, and the 8 pin connectors meet the requirements of differential signal consistency.
Insertion lifespan test: The male and female seats undergo 5,000 full stroke insertion and extraction cycles under a loading condition of 0.6N/Pin. The contact resistance change ΔR of all pogo pins is ≤ 1.3mΩ, with no physical wear or spring deformation. Johoty can provide a cyclic resistance curve graph for 8 pin connectors.
Waterproof rating certification test (IP67): Soak in 1 meter deep water for 30 minutes in the assembled state before removing. Perform insulation resistance and conductivity tests, and the insulation resistance between 8 pins is >1,000MΩ. The 8 pin connectors have no leakage, short circuit, or water ingress marks. The testing environment has a temperature of 23℃ and 60% relative humidity.
Blind insertion test of foolproof mechanism: A total of 300 tests were completed by 30 engineering personnel simulating blind insertion actions. The correct connection rate reaches 100%, and the insertion failure rate in the wrong direction is 100%. Mechanical limits are installed in all directions for industrial, automotive, and medical applications that do not require visual insertion and removal.
High temperature/high humidity stability test: Measure the contact resistance continuously for 168 hours in an environment of 85℃ and 85% RH, with a change of<1.0m Ω. The pogo pins of the 8 pin connectors are not oxidized, and the elastic structure is not attenuated. Meet the climate reliability requirements of industrial grade products.
Dynamic vibration connection stability test: Conduct a continuous test for 6 hours at a sine vibration frequency of 10-500Hz and a 3-axis resonance peak of 1.5mm/10g. Real time monitoring of 8 signals without interruption, failure determination: resistance interruption >1μs. Verify the reliability of 8 pin connectors in high vibration environments.
Salt spray corrosion test: pass the 96 hour 5% NaCl salt spray spray as per ASTM B117 standard. The surface of Pogo pins has no visible corrosion spots, and the increase in contact resistance is less than 0.8mΩ. Johoty’s 8 pin connectors are often required in port, marine, and outdoor terminal environments.
High frequency TDR impedance test (customized for differential lines): The differential pair has a reflection coefficient S11<-18dB within a 50mm connection path. Differential impedance control between 97~102Ω, supporting high-speed serial signal USB 2.0 and RS485 high integrity transmission.

FAQ
Is the insertion and extraction force of 8 pin connectors controllable and compatible with automated assembly? The design range of insertion force for each pin is between 0.25N and 5N. Depending on the pogo pin structure and plunger tip shape, the total force can be controlled at 2N. Suitable for robotic arms or Z-axis fixtures.
Can 8 pin connectors mix custom power and signal sharing? Support, a single group can be configured with high current pogo pins 3~5A and differential signal pins. We have mass-produced 2 power supplies, 6 signal structures, and EMI shielding shells. Attached are elastic impedance control and temperature rise curve diagrams.
How to confirm the compatibility between 8 pin connectors and standard connectors? STEP 3D models can be provided for customer board end structure reuse or collaborative design. Support the coordination and verification of customer supplied mother seats or PCBA packaging drawings. Provide an analysis report on contact surface misalignment, pin stress, and tolerance superposition.
Can the minimum pitch of 8 pin connectors be ≤1.00mm without affecting reliability? Support under size limitations. Under the condition of 0.80mm pitch, the fluctuation of connection resistance ΔR is less than 1.1mΩ. The structural stability has been verified through 5,000 insertions and removals. Customized 8 pin connectors are used in high-density environments to enhance plug stability.
Is the IP67 waterproof rating of 8 pin connectors effective when connected? Effective, IP67 testing includes immersion testing of 8 pin connectors after assembly. Soak at 1 meter without any water ingress or insulation failure for 30 minutes. According to IEC, provide a cross-sectional diagram of the sealing structure.
