Pogo Pins, spring loaded pins, feature high-precision design and outstanding electrical performance. With nearly 50,000 customized solutions, ranging from aerospace to smart wearables, from autonomous vehicles to high-speed communication devices. The diversity and reliability of Pogo Pin make it the preferred connectivity solution across multiple industries.

Pogo pins, commonly connect electronic devices for electrical signals or power transmission. They consist of a built-in small spring and a matching plunger housed in a barrel.
When press pogo pins are down, the spring is compressed, extending the plunger to form an electrical connection with its contact point. Upon release of pressure, the spring pushes the plunger back to its original position, breaking the connection.
Pogo pins provide stable and reliable connections through multiple engagement cycles. Due to their unique spring-loaded mechanism, pogo pins can compensate for minor assembly errors. This can ensure good electrical contact in various usages. They are widely used in circuit board testing fixtures, chargers, communication devices, medical equipment, and other electronics requiring reliable connections.
