SIGMA 688

Twister

Overview

The Sigma 688 offers reliable and fully automatic production of twisted wires at speeds of up to 5m/s with reliable OEM quality.

With high quality and maximum flexibility in setting up the fully automatic machine, the Sigma 688 simultaneously twists two individual wires to UTP wires for applications with high data transmission, as required in the automotive industry. The modular machine structure can be upgraded with up to two crimp and seal modules each. The EtherCAT modules ensures optimal processes. The optional X2880 terminal pre-orientation module can be used on one or both sides for small cross sections up to 1.0 mm² and for very short, open ends. Quality assurance is also automatically ensured by integrable systems such as the Q1250i for optical stripping monitoring, CFA/CFA+ crimp force monitoring or other elements.

Features

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.
