FASTON Terminals (Insulated and Uninsulated)
FASTON Terminals
Test Specifications
Operating Temperatures of
Materials and Finishes
FASTON terminals are
made available in brass and
phosphor bronze which can
be plated with tin or silver.
The line also includes a
selection of nickel plated
steel tabs and receptacles.
Certain products are
available in either pre-tin or
tin plated. Tin plate is the
electro-depositing of tin on
base metal over the entire
surface of the terminal
following the fabrication of
the terminal. Pre-tin plate is
the plating of tin on base
metal prior to fabrication
which produces exposed
base metal in the terminal
edge areas after stamping.
Stress Relieving of Brass or
Steel Receptacles
The process of stress
relieving is unique to TE
quick connects and is most
commonly used in the pro-
duction of those recepta-
cles designated as premier
line, including Ultra-Fast,
Ultra-Fast Plus FASTON
and PIDG receptacles.
Stress is introduced into
copper alloy or steel termi-
nals during the stamping
process. When metal strip
is formed into the receptacle,
the material is deformed
beyond its yield stress to
form it into its new shape.
This forming operation
leaves a residual stress
in the grain structure. The
orientations and magnitudes
of the forming stresses are
complex, but can exist in
the same direction as the
applied load. Thus, residual
stresses can reduce the
force necessary to open the
receptacle during the tab
insertion. Stress relieving
the terminal restores the
elastic spring properties
and improves receptacle
performance by reducing
the residual stresses. After
stress relieving, the recepta-
cle resists opening when a
tab is inserted, especially
where difficult or awkward
mating situations may cause
mechanical abuse.
Brass
Plain
Allowable connection
temperature* — 110°C.
Plain brass is used
frequently, where
applications have optimal
environmental conditions.
Tin Plated
Allowable connection
temperature — 110°C.
Tin plating of receptacle
and tab improves operation
at higher temperatures, and
in addition helps to protect
the connection against
corrosion.
Silver Plated
Allowable connection
temperature — 130°C.
Silver plated connections
allow the highest operating
temperature for brass and a
higher current-carrying
capacity.
* Allowable connection temperature
is the ambient temperature plus
temperature rise of the terminal at
normal operating conditions.
Phosphor Bronze
Plain
Allowable connection
temperature — 110°C.
Phosphor bronze is used
in applications where
brass would normally be
corroded, for example the
various freezing mixtures
and ammonias.
Tin Plated
Allowable connection
temperature — 110°C.
Tin plating of receptacle
and tab improves operation
at higher temperatures, and
in addition helps to protect
the connection against
corrosion.
Silver Plated
Allowable connection
temperature — 130°C.
Silver plated connections
allow the highest operating
temperature for phosphor
bronze and higher current-
carrying capacity.
Steel
Nickel Plated
Allowable connection
temperature — 250°C.
This combination allows a
reliable connection at high
temperatures, for example
in stoves, cooking
appliances, etc. For
optimum performance,
these nickel plated
receptacles are used with
compatible lead wires and
tabs that can be welded to
heating units.
