广州pogo pin manufacturers

The key component of elastic size, the choice of spring material is also very critical. The spring is made of high carbon steel material, commonly used materials are SWP (piano wire), stainless steel and copper. SWP (piano wire) is known to have good tensile properties. It can produce good mechanical life and large elastic value;

But the material is a highly magnetic material that tends to curl and corrode at high temperatures. Therefore, it must be treated before use; as for stainless steel material, it is a low magnetic material and can resist high temperature, so it is also a common material choice; beryllium copper has good fatigue resistance and low resistance, but its tensile strength Relatively poor characteristics, usually not a good choice for small wire diameters and large force values. The role of the spring in the pogo pin cannot be ignored, because the performance requirements and use environment of the pogo pin need to be considered when selecting materials.
