China D-SUB Cable Manufacturers Suppliers Factory - Customized D-SUB Cable Made in China

D-Sub Cable Manufacturer for Industrial, OEM & Wholesale Applications- Reliable D-Sub Cable Assemblies for Equipment Connectivity

Karobert supplies D-Sub cable assemblies for industrial equipment, control systems, communication interfaces, test and measurement equipment, computer peripherals and OEM applications.

D-Sub cables are still widely used where equipment requires a proven, mechanically secure connector with clearly defined pin assignments. Depending on the application, D-Sub assemblies can be configured with different contact counts, connector genders, cable constructions, shielding methods, pinouts and cable lengths.

Combo & Hybrid D-Sub Cable Assemblies
Mixed contact designs combining power (up to 40A), coaxial (75 Ohm / 50 Ohm), and signal contacts in a single D-Sub shell.

OEM Custom Pinout & Wiring Configurations

Straight-Through (Pin 1 to Pin 1, Pin 2 to Pin 2): For standard peripheral connections and serial extensions.

Null Modem / Crossover (TX/RX and Handshake Swapped): For direct device-to-device communication without modems.

Custom Pinout / Bridge / Y-Splitters: Internal wire jumpers, integrated resistors, custom drain wires, and hybrid terminations (e.g., D-Sub to RJ45, Terminal Blocks, or Flying Leads).

Industrial Cable Construction & EMI Protection

Standard office D-Sub cables fail in noisy factory environments. We use multi-layer shielding to preserve signal integrity around motors and drives:

Conductor Material

Tinned Oxygen-Free Copper (OFC), 28 AWG to 20 AWG

Primary Insulation

SR-PVC or High-Temperature Polypropylene (PP)

Inner Shield

100% Coverage Aluminum / Mylar Foil

Outer Shield

High-Density Tinned Copper Braid (85% to 95% Coverage) + Drain Wire

Outer Jacket Options

Flame-Retardant PVC (UL94V-0), High-Flex TPU, or Oil-Resistant TPE

Backshell & Hardware Options

Overmolded PVC Hoods: 360-degree internal copper foil wrapping for economical dust and moisture protection.

Die-Cast Zinc Alloy Hoods: Heavy-duty metal backshells with top/side entry for extreme EMI and mechanical impact.

Locking Hardware: UNC 4-40 thumbscrews, metric screws, slide locks, or hex standoff nuts.

Industrial Equipment D-SUB Cable suppliers

Quality Assurance: 100% Automated Testing Protocol

A physical connection does not guarantee data transmission. Every Karobert D-Sub cable undergoes end-of-line testing prior to packing:

100% Continuity & Short Testing

Verified using automated wire harness analyzers.

High-Voltage Insulation Testing (Hi-Pot)

Tested up to DC 300V to check dielectric strength.

Pin Mapping Verification

Ensures every internal conductor matches your approved 2D drawing.

Shield Grounding Verification

Checks 360-degree continuity from shell-to-shell for maximum noise isolation.

FAQ

Q: Can you build custom D-Sub cables from a physical sample or custom schematic?

A: Yes. For custom OEM projects or replacing legacy cables, you can send us a pinout chart, schematic diagram, or physical sample. Our engineering team will create a 2D production drawing for approval within 24 hours.

Q: What is the difference between DB9 and DE-9 cables?

A: "DB9" is the common commercial term used across the industry, but the formal technical designation is "DE-9" (Size E shell with 9 contacts). We supply both standard 9-pin configurations and high-density 15-pin (HD15) configurations using the same shell footprint.

Q: How do you prevent connector screws from loosening in high-vibration machinery?

A: We provide spring washers, thread-locking compounds, knurled metal UNC 4-40 screws, or slide-latch locking mechanisms specifically engineered for CNC equipment and automated machinery subject to vibration.

Q: What is your Minimum Order Quantity (MOQ) for custom pinouts and lengths?

A: We support prototype development with low MOQs starting at 50 to 100 pieces for custom pinouts or custom length configurations. Standard inventory cables are available in smaller batch quantities.

Q: Do you offer cross-reference replacements for major connector brands?

A: Yes. We offer direct cross-reference drawings and part numbers for major industrial D-Sub cable manufacturers (e.g., Amphenol, Molex, 3M), delivering equivalent electrical performance with custom lengths and factory-direct cost savings.
