I am glad you asked! I have 8 great reasons why:
- Reliable electrical connections -- all wire strands conduct current.
- No spreading of wire strands after a wire is clamped into a terminal block or other component.
- No fraying of wire strands, particularly in cases where the wire is very small or is removed often from its housing for testing purposes.
- No breaking of wire strands in cases of bending, wire stress or vibration.
- No unwanted contacts. Ferrules eliminate the possibility that strands might accidentally touch another termination and create shorts.
- Easy wire insertion in a terminal block clamp, particularly for smaller gauge wires (28 through 18AWG).
- Permanent crimping of two or more wires (jumper connection) before insertion in the wire clamp (twin wire ferrules).
- PLC's - Ideal for terminating wires in close proximity to each other. Eliminate possibility of glitches

Since you are probably already using
ferrules we probably don't need to go into too much detail about what they are.
Ferrules insure a reliable connection when you are terminating stranded flexible wire in terminal blocks, circuit breakers and other control devices.
Altech has a complete offering of ferrules including a universal ferrule hand crimper!
Insulated industry standard ferrules - our most popular, color coded by conductor size for convenient identification
Insulated DIN standard ferrules - comply with DIN requirements and ideal for export applications. These ferrules have a different color code than the industry standard.
Uninsulated ferrules - shorter lengths and uninsulated bodies offer advantages when making terminations in printed circuit board terminal blocks and blocks with smaller clamps or narrow widths.
Dual wire insulated ferrules - accept two conductors of the same or different size. Provide an efficient connection of multiple wires!
Need an assortment of ferrules? Altech offers an assortment box of either the industry standard or DIN standard insulated ferrules!
Last but not least... the
universal hand crimper that will crimp a wide range of insulated and uninsulated ferrule sizes!
