Custom Industrial Wire Harness Assemblies
Y.C. Cable manufactures custom industrial wire harness assemblies for machinery, control systems, sensors, equipment, automation, and other industrial applications.
Harnesses are manufactured according to customer-approved drawings, BOMs, wiring diagrams, pinouts, branch dimensions, connector requirements, electrical specifications, and operating conditions.
Industrial wire harnesses are commonly used when multiple wires and circuits must be organized into defined branches and routing paths inside machinery or equipment.

Industrial Wire Harness Configurations
Projects may include:
• Point-to-point wiring
• Multi-branch wire harnesses
• Machine wiring harnesses
• Control wiring
• Sensor and actuator harnesses
• Power distribution harnesses
• Signal harnesses
• Panel and enclosure wiring
• Internal equipment wiring
• Motor and motion-control wiring
• Connector-based harnesses
• Combined power and signal configurations
For individual cable connections, explore Industrial Cable Assemblies.
Machinery Routing & Branch Requirements
Industrial equipment may require harnesses to route through frames, cabinets, enclosures, moving equipment, or other restricted areas.
Important project requirements may include:
• Main harness length
• Branch lengths
• Breakout locations
• Connector orientation
• Routing paths
• Bend radius
• Service loops
• Cable retention
• Clips and mounting features

Power, Control, Signal & Sensor Wiring
Power Wiring
Power circuits should be defined around voltage, current, conductor size, termination, routing, and environmental requirements.
Control Wiring
Control harnesses may connect PLC-related equipment, control components, switches, relays, and other customer-defined devices.
Sensor & Actuator Wiring
Sensor and actuator connections may require specific connectors, pinouts, shielding, grounding, routing, or identification.
Signal & Data Wiring
Signal and data circuits should follow the customer-defined interface, cable, connector, shielding, and testing requirements.

Industrial wire harnesses may support:
• Manufacturing machinery
• Control systems
• Sensors
• Actuators
• Motor controls
• Machine vision equipment
• Automated production equipment
• Material-handling systems
• Industrial electronics

Frequently Asked Questions
What is an industrial wire harness?
An industrial wire harness combines wires, connectors, terminals, branches, protective coverings, labels, and mounting features into a defined wiring configuration for machinery or industrial equipment.
Can Y.C. Cable manufacture industrial wire harnesses from our drawings?
Yes. Projects can be reviewed using customer drawings, BOMs, wiring diagrams, connector information, branch dimensions, quantities, and testing requirements.
Can industrial wire harnesses include M8 or M12 connectors?
Yes, when those connectors are specified in the customer-approved product design and BOM.
Can harnesses be configured for harsh industrial environments?
Projects can be reviewed around requirements involving vibration, abrasion, temperature, moisture, oils, chemicals, electrical noise, and other operating conditions.
What is the difference between an industrial cable assembly and industrial wire harness?
A cable assembly commonly provides a defined connection between devices or components. A wire harness typically combines multiple circuits and branches into a larger routed wiring system.
