Probe Pin
XP3A
Electroplated Probe Pin for High
Reliability
• The Probe Pin is made of only one part.
• The flat structure helps you reduce the pin pitch in comparison
with standard probe pins.
• Separating the spring and relay achieves a stable resistance
and greater durability.
Features
■
Achieves the functions of four parts with one part
Standard Probe Pin
Plunger
Barrel
Electroformed Probe Pins
■
The electroformed Probe Pins use a flat structure.
This allows you to position the pins at any angle.
In comparison with round pins, these flat Probe Pins help you reduce
the pin pitch
