Technical Specifications:

Note: Detailed specifications for each product type (Ring Tongues, Forks, Disconnects, etc.) are extensive and presented in tabular format in the original document. Key specifications include Wire Range (AWG), Stud Size, Dimensions (W, C, L, E), Barrel Length, Barrel I.D., Maximum Insulation Diameter, and Packaging Quantities.

General Terminal Construction Features:

• One-piece, burr-free construction for maximum electrical conductivity.
• Electrical bright-tin plating for maximum corrosion resistance.
• Annealing to relieve stress points and assure maximum installed strength.
• Barrel-to-pad transition design minimizes flexing and bending.
• Open-end design for visual inspection of wire location.
• Multiple "V" grooves in barrels (#264 AWG) for maximum wire hold.
• Injection molded insulations (vinyl/nylon) rated at 221F (105C).
• Funnel barrel construction for easier wire insertion.
• Crimp ridge for positive tool location.
• Non-slip ridge for proper tool positioning.
• Beveled leading edge for easy wire insulation entry.

Barrel Styles:

• Non-Insulated: Butted Seam, Brazed Seam
• Vinyl Insulated: Brazed and Butted Seams
• Nylon Insulated: Butted Seam with Insulation Grip
• Heat Shrink: Brazed Seam

Frequently Asked Questions:

• Insulation Grip: Provides a "second" crimp on wire insulation for additional strain relief, ideal for high vibration applications.
• Tool Compatibility: Refer to pages 143-144 for a variety of tools compatible with 3M terminals.
• Insulated vs. Fully Insulated Disconnects: Insulated disconnects have barrel insulation only; fully insulated disconnects are insulated from barrel to receptacle/tab.
• Temperature Resistance: Non-insulated terminals withstand up to 347F (175C); insulated terminals withstand up to 221F (105C).

Terminal Numbering System Overview:

3M terminals follow a numbering system indicating Identity Code/Barrel Style, Wire Size Code (AWG), Tongue Code, and Product Availability. Example: MNG18-4 FB/SK.

Color Coding for Wire Range:

• Yellow: 2624 AWG
• Red: 2218 AWG
• Blue: 1614 AWG
• Yellow: 1210 AWG
• Red: 8 AWG
• Blue: 6 AWG
• Yellow: 4 AWG

Tools:

• TH-440 Scissors: Compact, 22-10 AWG, 6 electrical wiring functions, heat-treated carbon steel.
• TH-450 Scissors: Versatile, heavy-duty, 26-6 AWG, high-strength heat-treated carbon steel.
• TR-482 Ratchet Tool: Crimps barrel and insulation grip simultaneously (22-10 AWG insulated), field recalibratable.
• TR-490 Ratchet Tool: Crimps barrel and insulation grip independently (22-10 AWG insulated and non-insulated), field recalibratable.
