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 recommended tools for use with 3M terminals.
• Disconnect Insulation: Insulated disconnects have barrel insulation only, while fully insulated disconnects are insulated from the barrel to the receptacle/tab.
• Temperature Resistance: Non-insulated terminals withstand up to 347F (175C); insulated terminals withstand up to 221F (105C).

Glossary of Terms:

• Adapters: To interconnect two connectors already attached to wires.
• Block Fork: Same strength as a fork, designed for terminal blocks with flat sides against barriers.
• Butt Connectors: Feature chamfered barrel ends for fast wire insertion and a built-in wire stop. Must be crimped at both ends.
• Closed-End Connectors: Used for pigtailing two or more wires.
• Fork Terminals: Allow rapid wire connection, typically used on free-standing studs.
• Insulation Grip: Provides strain relief and vibration protection through a brass sleeve.
• Locking Forks: Spring-like tongue locks onto the stud, even if the mounting screw is loose.
• Parallel Connectors: Similar to butt connectors but with overlapped wires and a single center crimp, ideal for limited space.
• Pin Terminals: For installation in compression blocks, commonly used in Europe for terminating stranded wire.
• Quick Connect (Disconnect): Female part connects to a male tab via tongue, offering easy and quick disconnection.
• Ring Tongues: Standard, safe, and reliable tongue style, removable only after the mounting screw is removed.
• Tap Terminals: Require no wire stripping; lay wire in connector and crimp for connection.

Standard 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 ensure maximum installed strength.
• Barrel-to-pad transition design minimizes flexing and bending.
• Open-end design allows visual inspection of wire location before and after crimping.
• Multiple V grooves on smaller parts for excellent holding power.
• Injection-molded insulations (vinyl or nylon) rated at 221F (105C).
• Crimp ridge for positive tool location, reducing miscrimps.
• Funnel barrel construction for easy wire insertion without strand hang-ups.
• Nylon insulated terminals with grip feature a brass sleeve for optimum grip and strain relief.
• Non-slip ridge for proper crimping tool positioning.
• Beveled leading edge for easy wire insulation entry.

Barrel Styles:

• Non-Insulated (Butted Seam): Economical, used where special characteristics are not required.
• Non-Insulated (Brazed Seam): Silver brazed seam prevents wire escape during crimping.
• Vinyl Insulated (Brazed/Butted Seam): Features a flared, rigid polyvinyl chloride sleeve for easy wire entry and strain relief.
• Nylon Insulated (Butted Seam with Insulation Grip): Includes a seamless brass sleeve for grip and strain relief, with a step in nylon insulation for easier tool positioning.

Heat Shrink Terminals, Connectors, and Disconnects:

Offer superior moisture protection and corrosion resistance with adhesive-lined heat shrink material. Provide improved mechanical performance with enhanced pullout strength and strain relief. Durable heat shrink tubing resists abrasion and aging. Available in wire sizes 2210 AWG, color-coded for wire range identification.

High Temperature Terminals and Connectors:

Constructed of steel with nickel plating, rated for continuous use at 900F (482C). Ideal for high-temperature applications like ovens, motors, and light fixtures. No applicable UL or CSA standards for these high-temperature steel parts.
