Overview
Crimp Terminals, Disconnects, and Splices
Thomas & Betts is pleased to introduce Spec-Kon®crimp
terminals, disconnects, and splices. Ideal for OEM applications,
the Spec-Kon®line can be used anywhere a high number of
terminations are required every day, such as the wiring harness,
panelboard, telecommunications, and automotive industries.
The Spec-Kon®terminal offering includes:
• A broad selection of bulk-packaged loose piece terminals in non-insulated
and insulated varieties, including male and female disconnects, rings,
forks, pins, blades, butt splices, wire joints and bullet connectors.
• Terminals on mylar tape for automated applications, including the new
KT-2500 power tool for frequent, repeated crimps.
• The ERG-2500 ergonomic hand tool, which crimps all sizes of insulated
barrel-style Spec-Kon®wire termination products.

Features and Benefits of Spec-Kon®Terminals
• Internal barrel serrations—During crimping, the wire will cold flow into
serrations, giving lower resistance connections and improving tensile strength.
• Size marking—Wire range is stamped on the tongue (metric and English) for
easy access to the terminal size without drawings/packaging.
• Electro tin plating—Provides excellent corrosion resistance, superior finish for
better-looking installation.
• Ergonomic hand tool—Ergonomically designed ERG-2500 completes a UL
listed crimp while requiring substantially lower handle forces.
• One tool for all insulated products—Thomas & Betts offers a single tool that
crimps the entire range of standard insulated terminals, disconnects, and butt
splices. Many competitors require 2 to 4 tools to cover the same range.
• Color coding—Insulators are color coded for specific wire size
(red=22-16AWG, blue=16-14AWG, yellow=12-10AWG). Red=8AWG,
blue=6AWG.

Nylon Insulated Terminals
• Sleeved barrel—Ensures barrel does not separate during crimping.
• Molded insulators—Molded insulators ensure consistent shape and quality,
shaped entry speeds installation and reduces wire hang up.
• Metal insulation sleeve—Sleeve crimps wire insulation, providing
high-vibration resistance and conductor strain relief.
• Nylon material—Ideal for harsh environments. Provides excellent chemical,
impact and abrasion resistance.
• Ratings—UL Listed, cULus Listed, CSA, 600 V at 105ºC.
Vinyl Insulated Terminals
• Brazed seam—Ensures barrel does not separate during crimping.
• Molded funnel entry insulators—Funnel entry speeds installation and reduces
wire hang up. Molded insulators ensure consistent shape and quality every
time.
• Insulation crimp—The insulator mouth is flared to speed installation and
accommodate thicker insulated wires. Also, provides insulation support strain
relief in high-vibration applications.
• Vinyl material—Economical, moisture resistant and flame retardant (UL94V-0)
• Ratings—UL Listed, cULus Listed, CSA, 600 V at 105ºC.
Non-Insulated Terminals
• Brazed seam—Ensures barrel does not separate during crimping.
• Chamfered barrel entry—Smoothing the barrel entry edge facilitates wire
insertion.
• Ratings—UL Listed, cULus Listed, CSA, 2000 V.
