• 0342 receptacle uses
Mill-Max’s new #42 Power
Contact. This receptacle will
accept the Ø.061±.002
power pins of ¼ 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.

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 Ø.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.
