SurLok Compression Lug with
Plastic Housing using RADSOK
®
Technology
TM
FOR POWER DISTRIBUTION APPLICATIONS
The SurLok™ non-environmental compression lug is a
field installable, highly reliable alternative to common
compression lugs. An industry standard U-Indent/ Clamshell
or 4-indenter crimp tool may be used to perform the
termination on the wire, thus eliminating the need to
purchase special torque tools.
The head of the pin locks into place once mated to the
RADSOK
®
connector. The plastic housing snaps over
the connector and acts as a protective cover. The plastic
housing is available for all sizes. This secure connection
ensures voltage and amperage levels will be maintained
throughout the duration of the application.
The RADSOK
®
high amperage contact technology utilizes
high tensile strength properties of the stamped and formed,
high conductivity alloy grid to produce the low insertion
force while maintaining large conductive surface area.
Features and benefits of Amphenol’s SurLok
over other compression lugs:
• High current rating, high ampacity in a smaller package
• High reliability; meets or exceeds the electrical
performance of bolt-on compression lugs
• Easy field install - crimp with standard color-coded dies
(Udie and 4 indenter). No torque wrenches required.
• Integral locking feature plus locking cap
• RADSOK
®
technology boosts the ampacity by 50%
or more compared to mil-spec contacts. RADSOK
®
contacts provide the advantages of low insertion force
and high cycle durability.
• RoHS compliant

Ideal markets include Medical and Test Equipment, Process Control, Heavy
Equipment and Rail. Any applications that use high current, frequently plugged &
unplugged cables or a “plug and play” setup would be an ideal “fit” for
the SurLok.
Technical specifications of the Amphenol Plastic Surlok :
Engagement force: ~2 lbs. – 5 lbs. mating insertion and ~10 lbs. – 15 lbs. locking
Separation force: ~10 lbs. – 15 lbs.
Contact surfaces are silver plated on the pin and socket.
Wire crimp barrel is matte tin per industry standards.
