PogoPin is a spring-type probe formed by the three basic components of Plunger,Barrel and Spring through high precision equipment riveting and pressing, also known as Spring loaded pin, Spring probe pin, Spring Loaded, PogoPin connector.
The bottom of the Pogo Pin’s Plunger is usually a slant structure, and the function of the slant structure is to ensure that the Pogo Pin keeps the Plunger in contact with the inner wall of the Barrel when working. The current is mainly passed through the gold-plated Plunger and Barrel to ensure the stability and low impedance of the Pogo Pin.
