Plate diameter
The plate diameter describes the diameter of a disc-shaped contact area (in mm) and influences the distribution of contact force as well as the effective contact area. It is a relevant parameter for the design of contacts in test technology and has a direct influence on contact quality, contact pressure, and behavior under different surface structures.
FAQ
It determines the effective contact area and influences the surface pressure as well as the distribution of the spring force at the Test Point.
At the same spring force, a larger plate diameter results in lower surface pressure, while a smaller plate diameter increases the pressure.
For rough or textured surfaces, an adjusted plate diameter can improve contact stability and electrical transfer.
