Terminals
Selective Annealing
Because of the mechanical strength of
copper, an installer can experience
fatigue associated with repeated
installations. For this reason Thomas &
Betts puts our terminals through one
more step called selective annealing.
This process leaves the barrel soft
enough to crimp and form around the
wire. However, we “cold form” the
tongue during the manufacturing
process so it remains strong. This is
done so the tongue can withstand
repeated bends and bolt tightening
strain common in most electrical
installations. Many competitors
attempt to accomplish similar
goals by removing valuable
material or using a softer
copper which has lower
conductivity. This increases
electrical resistance as well as the
odds for shorting and downtime.
Anti-Rotational Tongues
This is a unique feature to the Thomas &
Betts ring tongue terminal. This design
prevents terminal shorting by keeping the
terminal secure in the terminal block. The
installer can place a greater number of
terminals closer together without worry.
Proper Identification
We identify all terminals with Thomas &
Betts initials, T & B. We also indicate wire
and stud sizes. These markings are
clearly visible on the surface of the
tongue, taking any guesswork out of
replacing or reordering additional parts.
Our superior bright plating also assists in
visibility.
All Sta-Kon
®
Terminals are
Deburred and Degreased
To ensure a Sta-Kon
®
terminal is properly
plated and insulated, all our parts are put
through a process which cleans and
smooths the terminal of any
manufacturing by-products, mainly
grease, oils and sharp edges. Many
competitive products do not put their
product through such rigorous finishing.
Platings/Finish
Electroplated-Tin is standard. All others
require minimum order quantities and
are generally not stocked. Alternative
platings as follows: Gold, Silver, Tin-
alloys, Nickel, etc.
The following finishes are available on
most one-piece Sta-Kon
®
terminals:
Finish Suffix Spec.
Gold Plate GP MIL-G-45204
Type II, Grade B,
C, D, Class O
Nickel Plate NP QQ-N-290 Class 2,
Grade G
Plain Finish PF None
Silver Plate SP MIL-T-16366 Type I
or II, 400° F, 204° C
Tin Plate TP MIL-T-10727 Type I
To order add the indicated suffix to the
regular catalog number.
