Industrial Cable Assembly Manufacturer for Machinery and Automation

Industrial Cable Assembly Supplier for Machinery, Automation, and Data Infrastructure

Nexharn produces industrial cable assemblies for machinery OEMs, automation integrators, field equipment builders, control system manufacturers, and data center infrastructure programs. Assemblies are configured to connector specification, protocol requirement, IP protection class, cable grade, and application environment — from factory floor fieldbus cabling to high-density data center interconnects.

HS-Link Cable Assemblies for Industrial Robot and Motion Networks

HS-Link is a high-speed proprietary communication interface used in KUKA robotics systems and select industrial motion control applications. HS-Link cable assemblies carry real-time synchronisation, motion command, and feedback data between robot controllers and peripheral drive systems at speeds that require precise impedance control, low-capacitance construction, and multi-layer shielding to prevent signal degradation.

Nexharn manufactures HS-Link compatible cable assemblies to OEM drawing and connector specification for robot system integrators, aftermarket maintenance programs, and production line builders. Key construction requirements include differential pair symmetry, foil-plus-braid shielding, and impedance-matched cable selection. Custom overmolds, boot designs, and pull-tested terminations are available for demanding robot installation environments.

• KUKA KR robot series HS-Link interface cable assemblies
• Controller-to-servo drive high-speed data link cables
• Robot cell wiring harnesses with mixed power and signal circuits
• Flexible-grade HS-Link cables for drag chain and robot arm installation

MRJ21 Cable Assemblies for Data Center and Industrial Network Infrastructure

MRJ21 connectors (also referenced as Amphenol mRJ21, RJ-21, or Telco connectors) provide a high-density interface carrying up to 24 pairs of Ethernet, analog, or T1/E1 signals in a single compact housing. MRJ21 cable assemblies are the dominant interconnect solution for high-density data center patch panels, Cisco and Nortel blade chassis, industrial ethernet switching infrastructure, and telecommunications distribution frames where per-port space and cable management efficiency are critical.

A standard MRJ21 assembly terminates one 24-pair connector to individual Cat5e, Cat6, or analog pairs at the breakout end — commonly called a fan-out or octopus cable. Nexharn manufactures MRJ21 cable assemblies in standard and custom configurations including:

• 24-port MRJ21 to RJ-45 breakout cables (Cat5e and Cat6)
• MRJ21 to 110 punchdown or Krone block termination for telecom frames
• MRJ21 to MRJ21 straight-through patch cables for chassis-to-patch-panel runs
• Custom length, custom boot colour, and custom label programs for structured cabling contractors
• Industrial MRJ21 assemblies with ruggedised jacketing for factory floor network infrastructure

Data Center Cable Assemblies and High-Density Interconnects

Modern data centers require cable assemblies that combine high port density, reliable performance at Cat5e / Cat6 / Cat6A or fibre specifications, and cable management solutions compatible with structured cabling standards (TIA-568, ISO/IEC 11801). Nexharn supplies data center cable programs including:

• MRJ21 fan-out cables for blade server chassis and high-density switching
• Pre-terminated Cat6 and Cat6A patch panels for structured cabling projects
• InfiniBand and SAS breakout cable assemblies for server interconnect programs
• Custom-length horizontal and vertical cable management runs with pre-tested continuity

Industrial Network Connector Types Supported

• D-Sub connectors — DB9, DB15, DB25, DB37 for legacy fieldbus, serial, and instrument interfaces
• MRJ21 / RJ-21 — 24-pair high-density Ethernet and analog multiplex assemblies
• HS-Link proprietary — KUKA and motion-control robot communication interfaces
• RJ-45 / SFP / LC duplex — standard industrial Ethernet and fibre patch cords
• Deutsch DT / Molex Mini-Fit — power and signal connectors for machinery and mobile equipment
