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.
Features of SMT POGO PIN:
- Ball strucutre to protect spring from high current.
- Thru-hole tail for secure soldering.
- Solder-cup tail for wire attachment. (Recommended AWG19 or
greater)
- Available 2A per pin
- Working Height: 2.5mm ~ 8.3mm
- Spring Force: 0.9N or 1.08N
- Tube Bottom Diameter: 1.8mm ~ 2.5mm
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 is to realise the connection between Board to Board
- Pogo pin usually has vertical connection and right angle connection
- Pogo pin is also to realise the connection between cable and device
