Frequently asked questions
Where are pogo pins like this used?
They are used as spring contacts for test fixtures, programming jigs and temporary connections to PCB pads. They are normally held in a socket block or a fixture, so the pad or hole must suit the 0.68 mm tip.
Can it carry a high current continuously?
The listing rates it at 3 A. Keep the continuous current at or below that rating and allow for the contact resistance of 50 mΩ, which causes some voltage drop and heating.
