About HAUFE GmbH
HAUFE GmbH is a specialist in the development and production of flat cables (FFC, Flexible Flat Cable) and printed circuit board connectors as well as in the cutting and rewinding of precision metal and copper strips. The laminated flat cables are made from bare or tinned copper conductors combined with high-quality PET or PEN insulating films and are customised, folded, fitted with exposed conductors (window technology) or assembled with crimp contacts and connectors according to customer requirements. The product range includes FFC flat cables, flexible busbars, LED flat cables (LED-CONN), jumpers (flat ZIF and RFR), Flexcrimp connector systems as well as complete cable sets and wiring harnesses. Production takes place at two sites in Saxony, Chemnitz/OT Grüna and Hohenstein-Ernstthal, from sample production to volume production. Customers come from the automotive sector (wiring harness, door and roof area, vehicle sill trims), mechanical and plant engineering, medical technology and the general electrical industry. The group also includes HAUFE Assembly GmbH as a cable assembler.
