Reliable DB9, DB15, DB25 and Custom D-Sub Cable Solutions for Industrial and OEM Applications

Yihetai manufactures custom D-sub cable assemblies for industrial equipment, automation systems, control panels, communication devices, testing instruments, medical equipment and OEM electronic products. For equipment that requires multi-branch wiring, signal connection and power distribution, we can also provide custom industrial wire harnesses based on your drawings or samples.

Whether you need a simple DB9 serial cable, a shielded DB25 cable assembly, an overmolded VGA HD15 cable, or a fully customized multi-branch D-sub wiring harness, our engineering and production team can build the cable according to your drawing, sample, pinout or application requirements.

What Is D-Sub Cable Assembly?


A D-Sub cable assembly is a cable solution using D-Subminiature connectors such as DB9, DB15, DB25, DB37 or HD15 connectors. These connectors are widely used for signal transmission, data communication, control interface, serial communication and equipment connection.

Common D-sub connector types include:

Connector TypeCommon Use
DB9 Cable AssemblyRS232 serial communication, control interface, industrial equipment
DB15 Cable AssemblyVGA, joystick interface, control signal or custom I/O wiring
DB25 Cable AssemblyParallel port, industrial I/O, test equipment and legacy systems
DB37 Cable AssemblyMulti-signal industrial interface, data acquisition and control wiring
DB50 Cable AssemblyHigh-density signal connection and multi-channel control systems
High-Density D-sub CableCompact equipment requiring more pins in limited space

At Yihetai, each D-Sub cable assembly can be manufactured according to customer drawings, samples, wiring diagrams or technical specifications.

D-sub Pinout, Wiring & Signal Definition

For D-sub cable assemblies, pinout accuracy is critical. A wrong pin assignment may cause communication failure, signal error, device malfunction or equipment damage.

Yihetai can manufacture D-sub cables according to customer pinout drawings, wiring diagrams, samples or device interface definitions.

Design ItemWhy It Matters
Pin AssignmentDefines signal, power, ground or control wiring
Connector GenderMale or female connector must match the equipment interface
Straight-Through WiringUsed when pin 1 connects to pin 1, pin 2 to pin 2 and so on
Cross WiringUsed for certain communication or control requirements
Grounding DesignHelps improve signal stability and reduce interference
Shield ConnectionImportant for industrial and EMI-sensitive applications
Wire Color CodingHelps production, inspection and maintenance
LabelingUseful for control panels, equipment assembly and field service

For industrial, medical, communication or test equipment where signal stability is critical, Yihetai can design shielded D-sub cables with foil shield, braid shield, drain wire and metal hood options. We also manufacture custom EMI shielded cable assemblies for applications with higher anti-interference requirements.

Hood DirectionStraight hood, angled hood or custom cable exit direction
Locking MethodThumbscrew, screw lock, latch or custom locking structure
Mounting StylePanel mount, cable mount or equipment interface installation
Strain ReliefMolded tail, clamp, boot or custom strain relief
Shell PlatingNickel-plated or project-specific option

For industrial equipment, vibration environments or frequent plugging applications, screw lock, metal hood and strain relief design should be confirmed before production.

D-sub Termination & Cable Structure Options

Different D-sub cable projects require different termination methods. Yihetai can customize cable structure according to your wiring method, PCB layout, control cabinet design or equipment interface.

Termination TypeTypical Use
Solder Cup D-subFlexible for custom wiring and small-batch projects
Crimp D-subSuitable for stable production and selected connector systems
IDC D-subCommon for ribbon cable and board-to-panel wiring
D-sub to Open WireUsed for control cabinets, PCB wiring and custom installation
D-sub to TerminalUsed for PLC, industrial equipment and terminal blocks
D-sub to Board ConnectorUsed for internal equipment wiring and PCB connection
D-sub to Mixed ConnectorD-sub combined with JST, Molex, terminal, RJ45 or other connectors
Overmolded D-subProvides strain relief and professional appearance

For communication devices and mixed-interface equipment, D-sub connectors can be combined with RJ45, terminal blocks, JST, Molex or other connector types. For network-related equipment, Yihetai can also supply custom RJ45 Ethernet cable assemblies as part of a complete signal connection solution.
