In industrial and embedded applications, a cable is often more than a simple connection between two devices.

While standard USB cables are widely available, many professional applications require a custom solution that considers connector compatibility, power requirements, data performance, cable length, installation environment, and long-term reliability.

Alvin’s Cables recently developed a custom Bulgin USB 3.0 Type-A to USB-C cable assembly for an embedded computing application using an Orange Pi 5 Plus single-board computer.

The project required a cable that could combine:

Industrial-grade Bulgin USB connectivity
USB 3.0 data transmission
High-current 5V power delivery
Custom cable length
Reliable fixed installation

This project demonstrates how custom cable development requires understanding the complete application, not just matching two connectors together.

Customer Requirement: Industrial USB Power and Data Cable

The customer needed a custom cable with the following configuration:

Connector A: Bulgin PX0840/A3/1M00 USB 3.0 Type-A
Connector B: USB Type-C Male
Cable Length: 1200 mm end-to-end
Data Requirement: USB 3.0 communication
Power Requirement: 5V power delivery
Application Device: Orange Pi 5 Plus
Installation Environment: Fixed installation

The cable would primarily be used for power, while maintaining USB data capability for communication.

Although this may appear to be a standard USB cable application, the combination of industrial connectors, high-current power requirements, and USB 3.0 data transmission created several engineering considerations.

Engineering Challenge: Balancing Power Delivery and Data Performance

For a USB cable used in professional equipment, current capacity alone is not enough.

A cable must also maintain stable voltage at the connected device.

When current increases, resistance from conductors and connectors can create voltage drop. In low-voltage applications such as 5V power systems, even a small voltage loss can affect equipment stability.

Our engineering team evaluated the cable design with two primary goals:

Reliable Power Delivery

The power conductors need to provide sufficient current capacity while minimizing resistance and unnecessary voltage loss.

The cable construction must be selected based on:

Required current
Cable length
Connector limitations
Expected operating conditions

Maintaining USB 3.0 Signal Integrity

At the same time, the cable must preserve USB 3.0 performance.

High-speed USB communication requires careful attention to:

Differential signal pairs
Shielding
Cable construction
Connector termination

Combining higher-current power capability with high-speed data performance requires a more advanced cable design compared with a standard consumer USB cable.

Integrating the Bulgin USB Connector

The customer specified the Bulgin PX0840/A3/1M00 USB 3.0 Type-A connector, an industrial connector designed for applications requiring a more rugged connection solution.

Because this connector was not part of our standard cable inventory, our team evaluated the most practical manufacturing approach.

For custom cable projects, the best solution depends on multiple factors:

Connector availability
Required production volume
Development cost
Future production needs
Project timeline

By selecting the appropriate connector sourcing and assembly method, we were able to maintain the customer's preferred industrial interface while developing a practical production solution.

Designing Around the Actual Equipment

One of the most important steps in custom cable development is understanding the equipment being connected.

Instead of designing only around a specification such as “USB-C 5V power,” our engineering team reviewed the actual application: the Orange Pi 5 Plus.

Understanding the end device helps determine:

Power requirements
Expected operating conditions
Required cable construction
Potential limitations
Appropriate validation methods

This application-focused approach helps ensure that the final cable is designed for real-world use rather than only meeting a connector specification.

Custom Cable Assembly for Industrial Applications

Industrial customers often require cable solutions that are not available as standard products.

Common custom requirements include:

Industrial USB cable assemblies
USB-A to USB-C custom cables
USB 3.0 data cables
High-current USB power cables
Custom cable lengths
Special connector combinations
OEM cable assemblies
Low-volume and production cable manufacturing

Each application may have different requirements depending on the equipment, environment, and performance expectations.

A successful custom cable project starts by understanding:

What devices are being connected
How power is delivered
What data performance is required
How the cable will be installed
What environmental conditions it must withstand
