American Precision Assemblers (APA) has been supplying custom cable assemblies, wire harnesses, and other mechanical and electrical assemblies to global customers in a broad range of industries for more than 30 years. We strive to anticipate, meet, and exceed the needs of each customer with quick response times and superior service throughout the production process. Our ultimate goal is to become the supplier of choice for every customer. 

Our engineers have developed proprietary processes to create cable assemblies for all types of cables, all supported by stringent quality assurance methods.

What is Cable Assembly?

Cable assemblies are sheathed groups of cables packaged as one single component. They allow users to run related cables together, maintaining organization and optimizing space. Cable assemblies are also used to protect cables from undue interference or environmental risks. Cable assemblies offer an ideal solution for protecting myriad cable types, including coax, multi-conductor, ribbon, and many others.

Any industry or application that needs to protect wires and cables from rugged or harsh operational conditions can benefit from the use of cable assemblies. Industries that rely upon cable assemblies include:

  • Aerospace
  • Agriculture
  • Aircraft
  • Food
  • Industrial vehicles
  • Medical
  • Military and defense
  • Printing
  • Safety
  • Wire

Cable assemblies have applications in a much broader range of industries than those listed here, and APA is happy to customize cable assemblies for any use case. 

Cable Assembly vs. Wire Harness: What’s the Difference?

Cable assemblies are sometimes referred to as cable harnesses, and as such are also sometimes confused with wire harnesses. Both tools have a similar structure—a sheath used to hold wires or cables together—which makes it easy to confuse them. Even though the terms are sometimes used interchangeably, they are used differently. 

  •  Wire harnesses are simply an affordable organizational tool made from a thin layer of thermoplastic or thermoset. They tend to be used for applications in controlled, safe environments. 
  • Cable harnesses are constructed from sturdier materials, such as vinyl or thicker thermoplastics. They may be customized to protect wires from specific conditions, such as extreme temperature shifts, weather, friction, compression, moisture, and a variety of other potentially harmful environmental factors.
