Precise twisting even with short lengths and open ends

Sophisticated processing sets are available for short, open ends, for long and differently open ends, for short wire lengths and for small cross-sections.

Quick and safe setup directly on the crimp module

Sigma 688 ensures fully-automatic UTP production by one person. Two-hand operation enables efficient setup on the crimp module.

Pneumatic straightener unit including wire diameter indicator

The active straightener unit with fine rollers straightens the wire for optimal further processing and placement in the machine and is particularly recommended for wires with diameters of 0.13 - 1.5 mm².

Terminal pre-orientation module for simplified, further expansion

For cross-sections up to 1.0 mm², the X2880 terminal pre-orientation module, which can be used on one or both sides, simplifies subsequent placement and reduces reworking.
