INDEXUL certification for ferrule
Weidmüller has received worldwide
certification for a crimped wire-end ferrule
for the North American and Canadian
region: the connection as awhole has been
certified – not the individual components.
Underwriters Laboratories certified the
system, which means the wire-end ferrules,
together with the hand tools and automatic
strippers and crimpers used for the crimping
process.
UL approval applies to all insulatedwire-end
ferrules belonging to the cross-section
range 0.25-50mm
2
(AWG 26-1) – excluding
the 35mm
2
(AWG 2) cross-section version.
The classic wire-end ferrule is a tinned
copper sleeve, crimped onto the end of
the wire. Wire-end ferrules are used to insert
the conductor into a connection or
terminal compartment without splitting.
Tinning finely stranded wire-ends will not
avoid splitting, because the tin solder or
the tinned wire conductor will yield under
the pressure of the clamping screw.
Crimping provides a permanent electrical
and mechanical connection between the
wire conductor and the crimp contact.
In comparison with non-insulated ferrules,
wire-end ferrules with plastic collars offer an
enhanced level of electrical safety as well
as mechanical stability, and standardized
color-coded plastic ensures wire conductor
cross-sections are easily identifiable.
Wire-end conductors with plastic collars
provide a gas-tight connection between
the wire conductor and the ferrule. A twin
wire-end ferrule is also available.
TPE alternatives
For the first time, Teknor Apex Europe can
produce compounds spanning its entire
range of TPE chemistries at its plants in
Belgium and the UK, supporting European
plastics processors serving industries as
diverse as automotive, medical, and wire
andcable. Following two years of expansion
in Europe, and the reorganization of its
operations in the region to integrate sales,
service, and distribution, Teknor Apex now
provides the “broadest selection of TPE
alternatives available from a European
compounder,” according to Barry Galpin,
sales director for Europe.
“Over more than six decades, Teknor
Apex Company has acquired a wealth
of experience serving key industries like
automotive, consumer and industrial products,
electrical and electronics, and medical
devices, and now all of this expertise is
available to manufacturers in Europe,”
said Mr Galpin. “As a custom compounder
drawing from the region’s broadest portfolio
of TPE chemistries, Teknor Apex Europe is
well positioned to supply each customer
with precisely the right compound for an
application.”
