Cable Assemblies

Cable assemblies with various connectors, ribbon cables, processing of individual stands or the production of connection cables for servo drives.

What exactly are cable assemblies?

Cable assemblies are the manufacture and production of ready-to-connect cables, cable harnesses and complete cable harnesses including assembly with various connectors and contacts. These are required in many industries where the transmission paths are electronic, preferably for connecting cables for servo drives.

Activities and procedures in cable assemblies

The particular application, the quantity and the specific requirements of the customer determine which cable assemblies are used. Three connection methods are mainly used: crimping, soldering and insulation displacement connection (IDC) . Grade customer-specific developments with precision-fit design are in demand in addition to the standard solutions of cable assemblies.

Why design is so important in cable assemblies

Cable assemblies are an essential element of functionality in plants, vehicles, industrial equipment and processes. It is therefore all the more important to be able to rely on their functionality and performance. High demands are therefore rightly placed on the development of cable assemblies and cable harness production. To meet these, cable assemblies are designed as ready-to-connect segments, depending on the application. For complex applications, the cable assemblies are designed or represented three-dimensionally using CAD programs. This makes it possible to define concrete assembly points and further technical parameters such as lengths of the cables and fasteners already in the development phase.

Cable assemblies & cable harness production

We offer customized solutions for cable assemblies in all application areas. A wide product range of electromechanical components and cables allows us to meet almost all requirements. Our services apply to single pieces for sample and prototype needs as well as to large or small series.

We manufacture a wide range of connector and cable combinations for various industrial applications for the transmission of power, signals and data.

  • Production of connection cables for drive technology, mechanical engineering, automation, robotics, etc., among others.
  • Connection cables for e-mobility
  • Assemblies with round and rectangular connectors
  • Assemblies with flat ribbon cables
  • Single strand processing
  • Ultrasonic welding
  • Manufacturing of component potting
  • Manufacture of connecting leads for printed circuit boards:
    • Board-To-Board assemblies
    • Wire-to-wire assemblies


Our service includes labeling or marking of cables and wires according to customer requirements. We deliver in specified packages (for example, rolled and/or bundled). Cable and wire ends can be supplied pre-tinned or fitted with ferrules.

We manufacture cable harnesses and pluggable connections especially according to your specifications. Here, too, the production of individual pieces is part of our portfolio.


Cable Assemblies - UL Wiring Harness

For end products that contain cables and wires and are intended for the North American market, UL Wiring Harness labeling is often required. This ensures that the installed components can be traced.

RST has obtained UL certification as a manufacturer of cable assemblies to UL (Underwriter Labratories) and, with the Wiring Harness label to ZPFW2 (USA) and ZPFW8 (CANADA), ensures that all components and materials under UL file number E520455 comply with current UL standards.

On the one hand, this traceability program guarantees that UL-specific product requirements and processes for cable assemblies are met by our production facility. Second, it ensures the identification and traceability of all cable assemblies based on lot numbers, manufacturing dates and manufacturing locations. The outer packaging is marked with special labels to indicate that these cable assemblies have been manufactured in accordance with UL Wiring Harness requirements.

In particular, customers and prospects who supply cable assemblies as components for end-use applications in the North American market are assured of this. Underwriters Laboratories Incorporated continuously monitors compliance with the required standard in terms of components, materials and processes through inspectors using a validated and traceable process. Annual audits ensure that the specified standards are permanently maintained.

If you have a requirement for cable assemblies marked in accordance with UL Wiring Harness, please contact us. We look forward to your inquiry.
