Overview Experience the Sta-Kon advantage Thomas & Betts developed the first tool-applied solderless terminals and connectors more than 70 years ago in response to industry awareness of the need for better performance of electrical systems. Key Features and Benefits Metal insulation grip sleeve is included on all-nylon terminal for strain relief Long barrel selectively annealed UL Listed E9809 unless otherwise specified Deep Internal Serrations After the insertion of a wire into the terminals barrel, a deep, serrated interior ensures a large area of contact that lowers the resistance of a connection. With the mechanical force of the tool, the wire strands cold flow into the serrated interior. This guarantees electrical resistance lower than the wire to which it is applied. This feature also prevents pullout from vibration and mechanical strain. Deep internal serrations can be compared to the effective holding power of a well-treaded tire on a wet highway. Funneled Terminal Barrel Entry Funnel Entry Barrel This feature makes wire insertion faster and easier. A funneled barrel eliminates wire strand hang up upon insertion into the terminals barrel. The loss of even a couple of wire strands can have negative results on electrical efficiency and resistance to mechanical strain. Selectively annealed long barrel Longer barrel design Sta-Kon Long Barrel Design Color-coded insulators Brazed or overlapping seams If lowering electrical resistance, preventing wire pullout, eliminating a missed crimp and having an insulator that stays on the barrel during installation are your goals, then you must design a terminal with a long barrel. This also provides the insulator with additional surface area, holding tight to the barrel. Most competitive barrel lengths range from 2050% shorter than Sta-Kon terminals. The results are usually a stream of Anti-rotational tongue electrical failure, rework and added expense. Many competitive insulators Hardened tongue come off during crimping due to a limited barrel length.

That is why Thomas & Betts brazes the seam on our vinyl-insulated Sta-Kon terminals andoverlaps the seam on nylon-insulated terminals. Many competitive terminals have butted seams. This means increased chances for wirestrand loss, poor resistance, wire pullout, and electrical failure. If the installer doesnt position thetool exactly on the correct spot on the barrel, theres likely going to be animproper termination. The butted seam can also fold due to tool-applied pressure piercing the terminals insulation from the inside out. With Thomas & Betts brazed oroverlapped seam, the installer can crimp anywhere along the barrels surface. This provides up to 2.5 times the tensile strength of a butted Deep Internal Serrations seam terminal, guaranteeing proper electrical flow, void free. Selective Annealing Because of the mechanical strength of copper, an installer can experience fatigue associated with repeated installations. For Flat bottom box this reason, Thomas & Betts puts its terminals through one Electro-tin plating more step called selective annealing. This process leaves the Center reinforced spring barrel soft enough to crimp and form around the wire. However, detent for minimum we cold form the tongue during the manufacturing process so insertion force it remains strong. This is done so the tongue can withstand repeated Compound Spring Rails bends and bolt tightening strain common in most electrical installations. provide positive contact Many competitors attempt to accomplish similar goals by removing valuable after repeated insertions 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 Strands enter as a terminal block. The installer can place a greater number of terminals closer homogeneous group and together without worry. compact tightly under compression due to fully brazed seam 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 that 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. United States Technical Services www.tnb.com Tel: 901.252.8000 Tel: 888.862.3289 800.816.7809 G-3 Fax: 901.252.1354
