How to choose a Pogo pin connector?
1. Work schedule selection
The choice of Pogo pin connector must be based on the space used by the product and the scope of work. If the space is too small, the spring of the Pogo pin connector will be over-compressed, which will affect the service life. If the space is too large, it is likely to cause poor contact, unstable impedance, and instantaneous image interruption.
2. Selection of plating materials
The performance of the electroplating material in the Pogo pin connector is to improve conductivity, oxidation resistance, wear resistance, etc. Different materials have different functions. For example, gold has good electrical conductivity, and electroplated gold is usually chosen for products with high current and high impedance requirements.
3, the influence of coating thickness
Pogo pin connector will produce a certain amount of friction due to contact during use, so the thickness of the coating has a great influence on the service life of the product. When used to a certain limit, the coating will be damaged, which is likely to cause phenomena such as excessive resistance and unstable impedance. The coating of 100,000 Pogo pins must be thicker than the coating of 10,000 Pogo pins, so when choosing a product, choose the coating according to your needs.
4. The impact of elasticity
The contact force of the spring connector comes from the internal spring. The magnitude of the spring force will directly affect the impedance and stability of the spring. If the elastic force is too large, the friction coefficient will be increased, thereby shortening the service life of the spring.
