Pogo-pin connectors became very popular in the field of charging devices. Lately, you can find them also in an outdoor applications. Outdoor environment requires a special design, mainly to protect the contacts against humidity, water & salt spray. Protecting the pins & the entire connector against water is the main issue in the connector’s design. You may protect the internal mechanism of the pin (if necessary) by applying an o-ring between the plunger and the barrel. The pr

Rolling ball pogo-pins aim to solve the problem of electrical contact between moving parts. These special contacts, enable a continues signal transferring when contacts are shifting, sliding or rotating, without any signal’s interference. Moreover, they enable smooth mechanical movement with a constant strain. This is done by placing a special independent rolling ball at the top of the spring probe. A key point is the ball coating. The coating should withstand a massive erosi

It is difficult to use standard pogo-pin for high RF signals ( high RF means > 6Ghz). The structure of (at least) 3 parts—the plunger, the spring & the barrel and moreover, the connection between them, affect the signal negatively, and increase interferences. Today, there are some new options to transfer high RF signals through pogo-pins. A new design offer a “One piece spring contact”. In this pogo, the plunger and the bottom contact are directly connected—not through the sp
