Technical Specifications Summary:

3M terminals offer a variety of construction features for optimal performance:

• One-piece, burr-free construction: Maximizes electrical conductivity.
• Electrical bright-tin plating: Provides maximum corrosion resistance.
• Annealing: Relieves stress points for maximum installed strength.
• Barrel-to-pad transition: Minimizes flexing and bending.
• Open-end design: Allows visual inspection of wire location before and after crimping.
• Multiple V grooves: Ensure maximum hold on wire for excellent holding power (on #264 AWG parts).
• Injection molded insulations: High-quality, 221F (105C) rated materials with consistent wall thickness, funnel barrel construction, and crimp/non-slip ridges.
• Crimp ridge: Ensures positive tool location on the terminal barrel for fewer miscrimps.
• Funnel barrel construction: Facilitates easy wire insertion without strand hang-ups.
• Nylon-insulated terminals with grip: Feature a brass sleeve for optimum grip, strain relief, and vibration protection, with recessed sleeves for flash-over protection.
• Non-slip ridge: Aids in proper tool positioning for better workmanship.
• Beveled leading edge: Eases wire insulation entry.

Barrel Styles:

• Non-Insulated Butted Seam: Economical, with beveled mouth for easy wire insertion. Max temperature: 347F (175C).
• Non-Insulated Brazed Seam: Beveled mouth for easy wire insertion. Silver brazed seam prevents opening under crimping pressure. Max temperature: 347F (175C).
• Vinyl Insulated (Brazed and Butted Seams): Insulated barrel with flared, rigid molded polyvinyl chloride sleeve. Funneled for easy wire entry, providing excellent electrical contact and mechanical stress relief. Non-slip ridge for tool positioning. Color coding indicates wire range. Continuous operating temperature: -40F to 221F (-40C to 105C). UL Listed and CSA Certified for 600V building wire and 1000V signs and lighting fixtures.
• Nylon Insulated (Butted Seam with Insulation Grip): Insulated barrel with flared, seamless brass sleeve and flared, molded nylon sleeve. Funnel portion of brass sleeve aids wire positioning. Excellent electrical contact and mechanical stress relief. Crimp tool positioning is nearly mistake-proof due to a nylon insulation step. Color coding indicates wire range. Continuous operating temperature: -40F to 221F (-40C to 105C). UL Listed and CSA Certified for 600V building wire and 1000V signs and lighting fixtures.

Heat Shrink Terminals, Connectors, and Disconnects:

Offer superior moisture protection and improved mechanical performance with adhesive-lined heat shrink tubing. They resist abrasion, scoring, and cut-through. Available in wire sizes 2210 AWG, color-coded for wire range identification, with transparent tubing for visual inspection.

High Temperature Terminals and Connectors:

Frequently Asked Questions:

• Insulation Grip: Provides a "second" crimp on wire insulation for additional strain relief, excellent for high vibration applications.
• Tool Compatibility: Refer to pages 143-144 for a variety of compatible tools.
• Insulated vs. Fully Insulated Disconnects: Insulated disconnects have barrel insulation only; fully insulated disconnects are insulated from barrel to receptacle/tab.
• Temperature Withstand: Non-insulated terminals up to 347F (175C); Insulated terminals up to 221F (105C).
