The RADSOK design provides lower milli-
volt drop at an increased current load. This
allows users to increase the current load
per circuit while reducing the total number
of circuits in the application, resulting in
lower overall costs.

Milli-volt Drop Performance
• LOWER CONTACT RESISTANCE
• LOW MILLI-VOLT DROP PERFORMANCE
• HIGHER CURRENT CAPACITY WITH MINIMIZED TEMPERATURE RISE
• RELIABILITY UNDER VIBRATION AND SHOCK
• HIGH QUALITY, CONSISTENCY AND LOWER COST
Resistance is primarily a function of contact, normal force, area and surface conditions. The RADSOK’s
multiplicity of flat grid surfaces assures the greatest possible contact area on the mating pin.
Results in Longer Life - Reduced contact pressure yields reduced wear. Thousands of insertion and
extraction cycles have been completed on RADSOK contacts with little apparent wear or degradation.
Insertion/extraction force can be tailored to meet the customer’s requirements. By varying the
degree of twist imparted to the inner grid, the insertion/extraction force (and likewise the grid element
normal force) can be customized for every application.
The RADSOK’s strongest benefit is its very low milli-volt drop. Because of the intimate contact pro-
vided by the spring force of the grid, the flat contact surface of the grid, and wiping action during
insertion, the contact is excellent for applications requiring a consistent milli-volt drop.
High current flow is due to the intimate contact each of the grid elements has with the mating pin. The
contacts available in RADSOK and the amperages are as follows:
Size 12 RADSOK can handle currents up to 35 amps. (Consult Amphenol Power Solutions for availabil-
ity on size 12 RADSOK).
Size 8 AWG can handle currents up to 69 amps.
Size 4 AWG can handle currents up to 120 amps.
Size 0 AWG can handle currents up to 250 amps.
Lower overall contact resistance reduces heat build-up, thereby allowing higher current capacities at
given temperature limits. Connectors with RADSOK contacts may be produced in various sizes with a
variety of amperage capabilities.
Since system inertia is minimized by the small package and the fact that the contact is under a spring
load, connectors with RADSOK contacts are able to withstand extremes in both vibration and shock
regardless of direction or intensity. The one-piece stamped grid is much more uniform and predictable
than a number of individual wires or conventional pin and socket design.
High speed, automated precision stamping and assembly technology ensure high quality, consistency,
and the lowest cost in this class of electric terminal.

RADSOK ADVANTAGES

Although actual data may vary with the style of
connector, typical thermal rise data after 500
cycles of durability is:
Size 8 AWG socket:
38°C @ 46 amps and 78°C @ 69 amps
Size 4 AWG socket:
21°C @ 80 amps and 47°C @ 120 amps
These are very favorable temperature rises
for the most demanding applications.
