Cable manufacturer and cable confectioner for specialized cables, special conductors, and ready-to-install cable assemblies
Sarek Kabel GmbH
71334 Waiblingen (Gottlieb-Daimler-Str. 15)New on Amplifa
Cable Manufacturer and Cable Confectioner since 1983
Sarek Kabel GmbH is a medium-sized, owner-managed company in Waiblingen near Stuttgart, specializing in cable production, cable development, and cable assembly. As one of the few cable confectioners in Germany, the company manufactures many cables in-house, including flat round cables, spiral cables/coil conductors, and bundled shielded specialty cables. The value chain ranges from application-specific consulting and development to bundling, extrusion, jacketing, and braiding, up to hotmelt injection and potting, crimping, THT soldering of PCBs, and assembly of modules. Materials include copper strands (tinned, silver-plated), Polyether-PUR, TPE-V, fluoroplastics, and silicone. Customers come from mechanical engineering, automotive, commercial vehicle construction, sensor/actuator technology, electrical/electronics, equipment manufacturing, defense (NATO VG), and from research institutions and universities. Customers include institutions such as the Max Planck Institute for Plasma Physics and the Helmholtz Centre Dresden-Rossendorf.

Materials and Processes
Copper
Conductor material for cables and wires; invoiced based on copper basis price
Tinned fine copper strands
Increases corrosion resistance and flexibility, e.g., in CAN bus combined cables
Silver-plated wires
Used as conductors and shielding braids for corrosion protection in RTD lines
Polyether-PUR
Mechanically resistant, abrasion-proof outer jacket for hot channel tools and dynamic applications
TPE-V (halogen-free, flame-retardant)
Jacket material for combined cables with UL VW1 requirement and 125°C/3000h resistance
Fluoroplastics (e.g., Teflon)
Insulation and jacketing materials for temperature-resistant RTD lines, including FDA approval
Silicone
Cable jacket material for standard cables
Hotmelt (Injection/Potting)
Process for injecting and potting components, e.g., injection-molded connectors
Textile/Textile braiding
For textile cables with textile braiding including injection-molded connectors
Nonwoven fabric (Jacketing)
Smooths the stranded compound and glues it to the pressure-extruded inner jacket
