Product Features

Plunger pins (pogo pins) describe the tip of contact probes that contain springs, barrels, etc.
They are mainly used for the inspection of various electronic components, IC sockets, and printed circuit boards.
Spring-loaded connector pins are often used as connection terminals for camera lenses and batteries. In addition, they function as module connectors and built-in battery chargers in wearable terminals, which have gained attraction in recent years.
Also, for plating, Ni under-plating + Au plating is generally applied, due to the fact that Au plating is the best solution for applications requiring high corrosion resistance, high conductivity, and low contact resistance.
We manufacture these plunger pins (pogo pins) and spring-loaded connector pins with our FINECS original cold heading machines. Plunger pins (pogo pins) and spring-loaded connector pins are often manufactured by cutting. However, this process causes a lot of metal chips. In contrast, Cold heading enables a metal chip free manufacturing, combined with a faster processing and cost reduction.
