Custom Ethernet Cable Assemblies for Medical, Instrumentation, Test & Measurement and Communication Systems

SigmaRF manufactures custom Ethernet cable assemblies built to your exact length, category, shielding, connector and jacket specification. Where a standard patch cord falls short, our assemblies deliver stable, low-noise data links. Every assembly is 100% tested, and digital test certificates are available on critical builds.

What Is a Custom Ethernet Cable Assembly?

A custom Ethernet cable assembly is a purpose-built network cable, terminated with RJ45 or other connectors, and engineered for a specific device, environment and performance requirement. It removes the compromises of off-the-shelf cables: wrong length, poor strain relief, inadequate shielding or the wrong jacket material.

Capabilities

  • Categories: Cat5e, Cat6 and Cat6A
  • Connectors: RJ45 plugs, with options for boots, latches and right-angle styles
  • Shielding: unshielded (UTP) or shielded (F/UTP, S/FTP) for high-EMI environments
  • Jackets: PVC, LSZH and flexible or oil-resistant compounds
  • Customization: cut-to-length, color coding, labeling, branding and custom packaging
  • Quantities: prototypes to volume production

Types of Ethernet Cable Assemblies

Type Typical Use
Cat5e Gigabit connections in general equipment and control systems
Cat6 Higher bandwidth (250 MHz) with lower crosstalk for demanding instruments
Cat6A 10 Gigabit performance up to 100 m (500 MHz), for data-heavy and high-noise installations
Shielded vs. unshielded Shielded for EMI-sensitive equipment, unshielded for flexible, low-interference runs

Applications

  • Medical: imaging systems, patient monitors, diagnostic and lab equipment
  • Instrumentation: industrial controllers, sensors, data acquisition systems
  • Test & Measurement: automated test equipment, analyzers, oscilloscopes, lab benches
  • Communication: switches, routers, telecom racks and network infrastructure

Design Notes

  • EMI control: match shielding type and termination to the noise environment.
  • Flexibility: choose conductor stranding and jacket for the required bend radius and flex life.
  • Signal integrity: keep the category, length and connector quality matched to the data rate.
  • Cleanability and safety: select smooth, durable jackets, or LSZH where low smoke is required.
  • Strain relief: well-molded boots protect terminations from repeated handling.

Why SigmaRF

  • Dual manufacturing: flexible, cost-competitive volume production in Vadodara, India, with lead times as short as 2 days, plus precision finishing in the Cleveland, Ohio area.
  • Tested quality: 100% testing on every assembly, with digital test certificates on critical builds.
  • RF heritage: our experience in RF connectors and coaxial assemblies carries into every cable we build.
