Brief Introduction of SMT 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.
Structural Features of SMT POGO PIN
With ball structure: The ball inside allows more buffer, so result in a even more reliable connection.
Bias structure: The biased tail of the plunger creates a lateral force, so further improves the contact.
Back drill structure: The back drilled plunger increases the space for the spring, so allows a shorter pogo pin for tight space.
