0342 receptacle uses
Mill-Max’s new #42 Power
Contact. This receptacle will
accept the .061±.002
power pins of brick
DC/DC converters.
#42 contact has a very low
resistance path and is rated
for currents up to 50A.
#42 contact can be ordered
in standard receptacles that
use #03 contact; or it can be
specified as the spring
element inside custom made
receptacles for power
connector applications.
Mechanical Data #42 Contact:
Insertion/Extraction Force with a .061 (nominal) pin:
Compliancy Test (the “spring back” characteristic of the contact to accept a
.059 small pin after insertion of a .063 large pin):
(Insertion/Extraction Forces are in Newtons and measured with polished
steel gage pins having elliptical shaped tips)
Electrical/Thermal Data #42 Contact:
The electrical conductivity (resistance) of #42 contact depends on the con-
ductivity of the mating pin. Tests were made with both .060 Brass (26%
IACS) and Tellurium Copper (93% IACS) pins. Temperature rise was
measured with the receptacles mounted to simulate the heatsinking of a
multilayer circuitboard.
