A pogo pin or spring-loaded pin is a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry. They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration.

The name pogo pin comes from the pin's resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection. This helical spring makes pogo pins unique, since most other types of pin mechanisms use a cantilever spring or expansion sleeve.

Basic Specifications

Advantage
– Ball strucutre to protect spring from high current.
– Thru-hole tail for secure soldering.
– Solder-cup tail for wire attachment. (Recommended AWG19 or greater)

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.
