The Pylon Pogo
design features that enable our Pogo Contacts to achieve
the lowest, most consistent contact resistance available in
the marketplace.
The figure above depicts the biasing angle (ø), spring force (F), radial or side
force (F 1 ) and plunger force (F 2 ) of Biasing-Ball Pogo Contacts.
Contact Resistance
In evaluating contact resistance, low levels of resistance
are important. However, the more critical performance
measurement is the consistency of the low contact resistance.
Resistance measured as 8 milliohms at 1000 cycles must

These features are:
• The biasing ball construction of the Pogo Plunger
• Gold lined nickel silver tubing material for the Pogo
Pylon’s Biasing Ball Plungers
Biasing-Ball Construction* creates a radial component force
insuring a positive and uniform electrical junction between
the contact plunger and gold-alloy lining of the contact body.

cycles. The Biasing Ball design ensures that our Pogo
Contacts achieve consistent, low contact resistance. The
graph below plots the resistance of our P2663 Pogo series.
Note the consistency even to 3 sigma.
