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 erosion, caused by the contacts friction and at the same time, keeps the electrical (or RF) signal level stability.

Coating is made of thick hard silver over nickel.

Roll ball contacts are used in smart lens camera connectors, robot joints & circular quarter turn connectors.

ADR supply both single contacts and connectors of rolling ball pogo-pins.
