Amphenol® 97 Series Connectors are UL recognized and CSA recognized.
Company Introduction
Manufacturing connectors since 1932, we take pride that Amphenol
Industrial Global Operations (AIGO) is the undisputed leader in interconnect
systems for harsh environment applications. Such applications require a
high degree of engineering sophistication and precision manufacturing
capability. Innovations such as our RADSOK® contact technology can
supply gains of up to 50% in current carrying capability through the same
size pin vs traditional contact designs. Connectors utilizing the RADSOK®
technology outperform conventional power interconnect products and are
a better choice for the high current needs demanded by sophisticated
electronics.
AIGO's product lines consist of rectangular, standard, miniature, ber
optic, EMI/EMP lter and a variety of special application connectors.
Additionally, we manufacture value-add ex circuit and cable assemblies.
Our global manufacturing facilities include locations in Sidney, NY, Fraser,
MI, Midland, TX, Shenzhen and Zhuhai, China, Winnipeg, Canada, and
Nogales, Mexico. Our Sidney, NY facility is both ISO09001 certied and
qualied to MIL-STD-790 requirements.
The Server Environment
Modern servers are capable of millions of transactions per second.
They consume signicant amounts of power, and produce tremendous
amounts of heat while conducting the high amperage to manage these
transactions.
Excessive heat can cause malfunctions and irreversible damage to servers
while being expensive to manage. Therefore, minimizing temperature rise
is a key concern when designing power systems for data centers.
AIGO has industry leading experience engineering high current and
high density interconnect solutions. Our RADSOK® technology and our
proven engineering experience for harsh environments enable Amphenol
Industrial Global Operations to develop optimal solutions for server power
interconnect needs.
The undisputed leader in interconnect
systems for harsh environment applications
RADSOK® Technology Advantages
RADSOK’S twisted grid conguration allows for 50% more current to pass
through the same size pin, while providing increased reliability, ampacity and
cycle durability as well as lower insertion force, T-rise and voltage drop.
HIGH RELIABILITY
Unique RADSOK® design and construction technology create an electrical
contact interface that exceeds typical interconnect requirements. Applications
in aerospace, medical, industrial, automotive, mining, offshore, and other harsh
environments depend on the high reliability of Amphenol’s RADSOK® technology.
• LOW CONTACT ENGAGEMENT/SEPARATION FORCES
The hyperbolic lamella socket contact construction distributes normal forces
over a high percentage of the mating pin surface. This creates a smooth,
even engagement effort. This force distribution also contributes to excellent
performance in vibration applications with resistance to typical fretting corrosion.
• LOW CONTACT RESISTANCE
The large interface area between the socket lamella and pin surface result
in very low contact resistance, enabling the RADSOK® contacts’ high current
ratings compared to traditional power contact designs.
• HIGH MATING CYCLE DURABILITY
RADSOK® contacts with typical silver plating nishes have demonstrated survival
of 20,000 mating cycles. Specialized plating and contact lubricants can extend
cycle life to 200,000 matings or higher. Even with continuous exposure to harsh
environmental abuse (salt, sand, and high humidity), RADSOK® contacts have
been tested to maintain low contact resistance beyond 10,000 mating cycles.
RADSOK® Derating Chart – Temperature vs. Current
Based on single conductors in free air. Wire cross-section same size as pin
contact cross-sectional area.
High speed and high density electronics have driven demand for signicant
increases in the amount of power needed for power to board applications. To
meet the need for higher current density interconnects Amphenol Industrial
Global Operations developed the RADSOK® Power to Board series of
connectors. RADSOK® Power to Board solutions facilitate the distribution of
power with higher amperage, while allowing the design engineer to achieve
size and weight reductions.
Conventional interconnects are limited in their ability to deliver high current
without consuming excessive board surface area. The RADSOK® Power to
Board series of connectors incorporates a hyperbolic lamella socket contact
construction that provides more contact surface area. The high performance
contact enables higher current carrying capabilities with lower temperature
rises than traditional contact systems.
Amphenol’s RADSOK® Power to Board product line offers many options
for delivering high current and single-point connections to the PCB. Please
contact your Amphenol Industrial representative for product extensions and
custom applications.
RADSERT™’s compact footprint design can
deliver up to 120A of current to the board. The
high current density and small surface area
connection provides exibility of board design.
RADSERT™ contacts are available in either
press-t or solder termination.
The RADSOK® PGY™ provides a compact and
robust right angle power to board interconnect.
Designed to mate with either a 3.6mm or 5.7mm
pin, The RADSOK® PGY™ can bring up to 120A
to the board. The radial design of the RADSOK®
contact gives you more contact surface area
lowering temperature rise and reducing potential
heat related failures.
The RADSOK® PowerBlok™’s compact footprint
½” x ½” can supply up to 70A to backplane
power connections. Current is distributed over
16 compliant pins. The PowerBlok™ is available
for top or bottom entry and offered with a touch-
proof cover.

RadStack™
RADSOK® RadStack™ was
designed to address the need
for high current and small foot
prints for PCB mezzanine
applications.
RADSOK® Super Twist
Design Background
The RADSOK® Super Twist contact was developed to enable greater radial misalignment tolerance, or “oat,” in drawer and blindmate applications. Greater
radial gatherablility is achieved in the Super Twist (ST) contact by adding additional “twist” to a larger RADSOK® contact. Using a larger O.D RADSOK® creates
additional I.D clearance for the mating male pin while maintaining electrical and mechanical performance.

• Small form factor, 6.0mm, 8.0mm & 10.0mm
• Also offered with a plastic protective cover and
male pin

• Insulation resistance can meet 5000 M Ohms
• 500 mating cycles – minimum
• Insertion force : Max 7 lbs.; Separation force: Min 1.5 lbs.
• UL94-V0 (self extinguishing)
RADSOK® RadFin™
RADSOK® RadFin™ was designed to address the need for amperes greater than 100A while maintaining a small footprint for PCB applications. Another unique
feature of the RadFin™ is its ability to act as a great heat dissipating connector. This dramatically helps reduce T-rise with minimal air-ow required.
RADSOK® RADLOK™
Utilizing Amphenol’s latest R4 RADSOK® Technology, our RADLOK™ product line was designed to be compact and robust. Power Interconnect products in
today’s market often require additional mounting hardware (e.g. washers, clamps, bolts, nuts, etc.) making them prone to costly labor expenses for installation
and routine maintenance. Paired with Amphenol’s RADLOK™ PIN, the single nger operation lock feature allows end users to connect any power distribution/
storage system in a quick and secure manner. The RADLOK™ product line is the answer to industries where a custom, reliable, easy to install, rugged, and cost
effective solution is required.
