Salt spray corrosion test: After 96 hours, the contact resistance change is less than 2.3mΩ, and there are no signs of black spot corrosion. Metal stability in sea storage, outdoor equipment, or industrial atmospheres. According to ASTM B117, a 96 hour salt spray test was conducted, and all 3 pogo pins did not fail. The gold surface was intact, and the average change in contact resistance was 1.65mΩ.
Lateral force detachment test: Horizontal detachment force ≥2.1N, anti misoperation sliding out design verification. Pogo pins have structural anti detachment capabilities when forcibly offset or inserted.
