When pogo pins are used in a connector, they are usually arranged in a dense array, connecting many individual nodes of two electrical circuits. They are commonly found in automatic test equipment in the form of a bed of nails, where they facilitate the rapid, reliable connection of the devices under test (DUTs). In one extremely high-density configuration, the array takes the form of a ring containing hundreds or thousands of individual pogo pins; this device is sometimes referred to as a pogo tower.
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.

- Pogo pin usually has vertical connection and right angle connection
- Pogo pin is also to realise the connection between cable and device
