A Practical Alternative to Complex Industrial Wiring Structures
In industrial automation and control systems, cable assemblies are often designed with overly complex connector structures that increase manufacturing cost, installation difficulty, and maintenance time.
For many applications, a simpler and more standardized wiring approach can improve installation efficiency while reducing overall system cost.
One common optimization method is the use of a custom DB37 breakout cable combined with standard 2.8mm female spade terminals for flexible field wiring and easier signal distribution.

Why Traditional Industrial Cable Designs Increase Costs
Many industrial cable assemblies still rely on:
- Proprietary molded connectors
- Specialized terminal systems
- Complex interface structures
- Non-standard cable layouts
While these designs may be suitable for certain applications, they can also create:
- Higher connector procurement costs
- Increased assembly labor
- Longer replacement time
- More difficult field maintenance
In practical industrial environments, engineers often prefer wiring structures that are:
- Easier to install
- Easier to replace
- More flexible for integration
- More cost-efficient for volume production
DB37 Breakout Cable with 2.8mm Female Spade Terminals
A DB37 breakout harness provides an effective solution for multi-signal industrial applications where simplified wiring and flexible termination are required.
Instead of using expensive molded connector systems, this structure combines:
- Standard DB37 connectors
- Individual crimped spade terminals
- Organized cable routing
- Customizable pin mapping
This approach simplifies both manufacturing and on-site installation.

Manufacturing Considerations for Reliable Cable Assemblies
Industrial cable reliability depends heavily on manufacturing consistency and process control.
DB37 Connector Assembly
Each DB37 connector requires accurate soldering and pin-position verification to ensure stable signal transmission.
Terminal Crimping
2.8mm female terminals are typically crimped using calibrated applicators to maintain:
- Stable pull-force retention
- Reliable electrical conductivity
- Consistent crimp height
Cable Protection
Corrugated tubing is commonly used to improve:
- Abrasion resistance
- Cable routing organization
- Mechanical protection
Electrical Testing
Standard testing processes include:
- Continuity testing
- Pinout verification
- Visual inspection
These processes help improve long-term reliability in industrial environments.
Common Applications of DB37 Breakout Harnesses
DB37 cable assemblies are widely used in:
- Industrial automation systems
- PLC control cabinets
- CNC equipment
- Signal interface systems
- Test and measurement equipment
- Control panels
- Automation retrofit projects
Because DB37 connectors support multiple signal channels in a compact footprint, they remain a practical solution for industrial control applications.
Flexible Customization Options
Custom DB37 cable assemblies can be configured according to application requirements, including:
- Custom wire length
- Shielded or unshielded cable
- Different terminal styles
- Full or partial pin population
- Custom wire colors
- Braided sleeving or corrugated tubing
- Label printing and identification
This flexibility allows easier integration into different industrial systems.
Advantages of Simplified Industrial Wiring Structures
Compared with more complex cable architectures, simplified breakout harness structures can provide:
- Lower manufacturing cost
- Faster installation
- Easier maintenance
- Better serviceability
- Reduced replacement difficulty
- Improved cable management
For many industrial applications, standardized connector structures offer a more efficient long-term solution.
