RS PRO Butt Wire Splice Connector, Red, Insulated, Tin 22 → 16 AWG

RS PRO Insulated Crimp Butt Splice Terminals

From RS PRO, a selection of insulated ferrules or Butt Connectors designed for crimping electrical wires. The tube-shaped terminals act as a solderless cable joint allowing electrical current to flow safely from one wire to another. Professionally designed using high-quality materials, RS PRO’s range of butt splice terminals are used to repair, change or lengthen electrical circuits.

The RS PRO range of insulated crimp butt splice terminals are easy to terminate, once the wire has been stripped simply guide the wires into each end of the copper tube and crimp using a suitable tool. The compression style electrical connection provides good tensile strength while maintaining maximum contact with the wire. Constructed from high-grade copper with a colour coded vinyl or nylon insulation, the RS PRO series of butt splice terminals are an essential addition to any electrician’s tool kit.

Colour Coding

The insulated terminals or connectors sleeve is colour coded for easy wire size identification. The colours of the connectors relate to a wire range the terminal can accept. The sizes can be quoted in either CSA (cross-sectional area) or AWG (American Wire Gauge)

• Mini Yellow = 0.2 - 0.5 mm² or 26-22AWG
• Red 0.5 - 1.0 mm² or 22-16AWG
• Blue 1.5 - 2.5 mm² or 16-14AWG
• Yellow 2.5 - 6.5 mm² or 12-10AWG

Features and Benefits:

• Tin plated copper tube
• Wide temperature range -20° C to + 105°C
• High-grade Vinyl or Nylon insulating material (Nylon insulation for mini yellow terminals only)
• Colour coded for easy wire size identification
• Easy to crimp using a ratchet tool.
• Durable and reliable termination
• Extremely cost effective

Typical Applications:

Insulated terminals have been around for many years, they originated from the need for a solderless method to terminate wiring in military equipment. Butt splice crimps are used in a wide range of industrial, commercial and domestic applications. They can be found almost anywhere where an electrical connection is required. Some of the most common are

• Industrial control systems
• Automotive and transportation sector
• Machine building
• Electrical and electronic equipment
• Commercial and domestic appliances

FAQs

Is there a crimp tool that you can use for crimping the butt connectors?
Any good quality ratchet style crimp tool or plier tool designed for butt terminals would suffice. RS PRO offers a range of reliable, cost-effective tools. See typical part number 534-806.

What is the difference between un-insulated and insulated crimp tools?
Un-insulated crimp tools are typically used for general applications, whereas the insulated crimp tools have been VDE tested up to 1000 V, designed for use where electrical current is present.
