Why Custom DB Cables Matter
DB connectors—such as DB9, DB15, DB25, and DB37—remain widely used in industrial automation, communication equipment, instrumentation, and transportation.
However, off-the-shelf cables rarely fit real-world installation requirements, especially when it comes to pin configuration, cable length, environmental protection, or mechanical structure.
Custom DB cables ensure:
- Correct pin-to-pin mapping
- Higher signal integrity
- Proper fit within equipment layouts
- Better durability for industrial environments
- Reduced installation errors and downtime
For companies building long-life, stable systems, custom DB cable assemblies are an essential upgrade.
Key Specifications Before Ordering a Custom DB Cable
To ensure accuracy and efficiency, define the following parameters clearly:
1. Connector Type
- DB9, DB15, DB25, DB37
- Male or female
- Straight or 90° angled
- Screw-lock or tool-free design
2. Cable Type
- Shielded signal cable (RS232/RS485/TTL)
- Multicore control cable
- Industrial-grade oil-resistant or drag-chain cable
- Outdoor UV-resistant or waterproof cable
3. Pin Assignment (Critical for System Compatibility)
- Exact PIN-to-function mapping
- Cross-wiring or loopback requirements
- Need for wiring diagrams or schematics
4. Cable Length and Structure
- Standard or custom lengths (0.2m to 20m+)
- Single-ended or double-ended processing
- Sleeving, braiding, PVC/nylon mesh, or labeling
5. Housing and Protection
- Plastic shell or metal shielded shell
- Anti-interference design
- Waterproof housings for outdoor or harsh environments
These parameters directly affect performance, reliability, and life cycle.

Tips When Customizing DB Cable Assemblies
- Always verify pin definitions before production
- Choose shielded cable for EMI-heavy environments
- Confirm screw-lock and housing type to match device panels
- For outdoor use, specify UV-resistant or waterproof designs
- For long-distance transmission, evaluate signal attenuation
Attention to detail ensures stable long-term performance.
