The Mira 440 wire stripper is a great choice for wire harnesses with a large proportion of coaxial or triaxial cables. It is particularly suitable for small to medium-sized series runs. The rotary flat blades ensure the high level of precision required for coaxial connectors. The Mira 440 processes single-conductor wire and multi-core cable, as well as semiflex cables in the Mira 440 SF model. The comprehensive functions, simple operation and smart design make the machine a specialist for coaxial cable processing. 


Special discipline: Coaxial, triaxial and hybrid cables

The stripping of coaxial cables places high demands on the machine. Several thin, concentric layers are removed with a single gripper closure: insulation, metal braiding, foil and dielectric. The strip length must be exceptionally accurate as the tolerance ranges of coaxial connectors are very narrow. The Mira 440 models are perfect for these special requirements. They are also suitable for processing most wires and multi-core cables with and without shield.

Wide processing range

Covering outer diameters of up to 9 mm and strip lengths of 40 mm, the Mira models offer a very wide processing range for their class. The wire range is equally wide at 0.02 to 13 mm² and AWG 36 – 6. Thanks to the rotary incision, the machines are also suitable for most insulations such as cross-linked plastics, PVC or Teflon®. In all cases, the focus is always kept on precision.

Coaxial processing with the highest level of precision

Rotary incision has established itself as the best solution for coaxial cables. The Mira 440 and 440 SF rotary incision unit is equipped with centralizers that keep the wire precisely centered during the incision process. The smooth cutting surface of the blades is directed towards the dielectric to ensure perfect cutting quality. The strip length and incision diameter can be adjusted with a high level of precision in 0.01 mm increments.


Highly productive, fast and functional

When the wire is inserted, the trigger sensor starts each process automatically. Versatile functions, such as trimming, offset pull-off, stripping in several steps and twisting the strands, increase the standard of quality and productivity. The sequence function enables the time-saving processing of multi-coaxial and hybrid cables, which consist of a combination of single-conductor and multi-core cables, and coaxial cables, where the components can be processed one after the other. The Mira 440 and 440 SF also have an article library. All leads can thus be processed with reproducible quality. Intelligent search and filter functions find the articles quickly – and the barcode scanner provides even faster results. Password protection prevents unintentional modifications.

Cutting-edge, ergonomic design and a user-friendly interface

A high-resolution touch screen in smartphone-style provides quick access to all the machine´s features. Supported by a dial and help texts, the intuitive user interface is fun to use and simplifies training. The user interface, including hint texts, is provided in a variety of languages, so operators with different preferred languages can use the same machine. The comfortable wrist cushion enables a relaxed working posture. Since the safety cover can be quickly removed without tools, cleaning and maintenance is much faster and easier. An ergonomic handle makes the compact wire strippers highly portable.

Mira 440 SF

Semiflex cables usually have a dip-tinned outer conductor. This outer conductor behaves differently during cutting than braid or foil layers of coaxial cables. To meet the special requirements of semiflex cables, the Mira 440 SF comes with an optimized cutting geometry.
