Welcome to the PRECI-DIP Spring-Loaded Contacts product training module. This presentation will help designers and engineers understand the difference between a hollow piston pogo pin and a CLIP design pogo pin. Spring-loaded contacts with CLIP or hollow piston designs are two different types of technologies used in various applications. When failure and electrical discontinuities are not options, CLIP technology is preferred. The internal construction between hollow and CLIP design is completely different. As pogo with CLIP have been originally designed for military harsh environments, the design is both reliable and robust. The pogo with CLIP technology is taking advantage of the integrated multi-finger clip to provide a flexible and compliant contact point to transmit the current through the pin, while the pogo with a hollow piston contact point is rigid and unstable, causing discontinuities at the slightest shock. It is like making the comparison of a modern car with excellent shock absorbers to a cart with wooden wheels, highlighting the importance of having efficient suspension systems and materials in reducing the transmission of vibrations and shocks. Similarly, the difference in contact resistance in hollow contacts versus CLIP design can greatly impact the performance and durability of electronic devices and systems.
