The plunger and barrel of pogo pins usually use brass or copper as a base material on which a thin layer of nickel is applied. As common in electrical connectors, manufacturers often apply a gold plating that improves the durability and contact resistance.The springs are usually made of copper alloys or spring steel.

What is Pogo pin?

Pogo Pin is spring loaded probe which is made by precision instruments with riveting workmanship. It usually consists of plunger, tube and spring.

Pogo pin is generally applied in the precision connection inside the electronics products such as mobile phones, communication devices, automotive, medical devices, aerospace devices and so on. Since pogo pin is very fine probe, it can make the finished connector light in weight, small in size and exquisite in look when it’s applied in a precision connector.
