INSERTION FORCE AFTER THE THIRD
EXCHANGE OF A CONTACT
Due to the very low strain on the PCB hole an
exchange of pins in one hole is possible up to
3 times without a significant loss of retaining
force. Contacts can be exchanged at any posi-
tion within a press-in connection.
TRANSITION RESISTANCE
A significant advantage of the high push-out
force and the large contact area (contact length
min 1.4 mm or 2 mm for a 3.2 mm PCB) is the
very low transition resistance (≤ 0.2 mΩ) as well
as the vibration and corrosion free connection.
Given that the transition resistance between
male and female connectors in accordance
with DIN 41611 can be up to 20 mΩ, the
transition resistance of the press-in connection
can be virtually neglected.
AVX can guarantee a secure connection within
a frequency range of 10 - 2000 Hz at 20 G in
accordance with IEC 48 (sec) 334.
In the right hand picture we show
the contact length of the VARIPIN
into an 3.2 mm PC board. These
show a large connection surface
from section 1 to section 4 which
corresponds to a contact length of
more than 2 mm.
PRESS-FIT INSTALLATION METHODS
Right angle headers and receptacle connectors require a
press-in tool.
Vertical headers and receptacles do not require a special tool.
They are installed using the “Flat Rock” method. Flat Rock

termination involves the use of a flat metal plate, slightly
larger than the length and width of the connector. Installed in a
press, the plate pushes down on the connector in a uniform
manner until the connector is properly seated.
