DB37 Ribbon Cable Configurations and Specifications
Custom DB37 Ribbon Cable Manufacturer
BespokeCable supplies DB37 ribbon cable assemblies for internal equipment connections, control systems, and test installations. The range includes 40-position IDC-to-DB37 cables and DB37-to-DB37 configurations in gray or rainbow ribbon.
We can develop the cable around your signal map and mounting space, or discuss a replacement from an existing sample. For a 40-to-37 connection, the three additional IDC positions are recorded individually so the finished cable follows the equipment design rather than a guessed correspondence.

Product Configurations
P/N: BC-CAI014-IDMG
A gray ribbon connection from a specified 40-position IDC interface to a male DB37. It provides a flat internal route, while the wiring document defines all three positions without a one-to-one D-sub equivalent.
P/N: BC-CAI014-IDFG
Choose this configuration for a female DB37 endpoint and a matching 40-position board connection. Length and cable exit can be discussed based on the board location and clearance behind the D-sub.
P/N: BC-CAI014-IDMR
Rainbow ribbon makes the conductor sequence visible between the IDC end and the male DB37. It can assist with assembly comparison and fault-finding when used alongside the numbered connection map.
P/N: BC-CAI014-IDFR
A female DB37 and IDC configuration with a colored ribbon. Identify the board interface and any unused positions, then specify the routing so the connector can be reached during assembly and service.
P/N: BC-CAI014-DMMG
Two male DB37 endpoints serve matching female equipment interfaces. Specify the actual electrical map and retaining hardware independently of gender, with a finished length suited to the internal route.
P/N: BC-CAI014-DMFG
This mixed-gender gray ribbon assembly connects defined D-sub endpoints. It can be developed around an internal module or panel route where connector projection and the first cable bend control the fit.
P/N: BC-CAI014-DFFG
A female-to-female arrangement for two specified male interfaces. Include any shell connections and hardware requirements in the assembly drawing, alongside the signal map and cable orientation.
P/N: BC-CAI014-DMMR
Colored ribbon provides a visible conductor sequence between two male DB37 connectors. Use a distinct assembly reference when the equipment contains several similar-looking cables with different wiring.
P/N: BC-CAI014-DMFR
A mixed-gender option with a rainbow ribbon for a defined internal connection. Endpoint labels can make the intended installation clear, showing where the cable reaches different modules or service locations.
P/N: BC-CAI014-DFFR
The listed female-ended rainbow configuration is a starting point for your D-sub connection. Establish both endpoint details from the assembly drawing, then discuss length, hardware, and the required wiring.
One Assembly for the Board and D Sub Connection
An IDC-to-DB37 ribbon can carry a group of internal connections from the board to a defined D-sub endpoint. The flat profile helps when the route lies beside a panel or follows a PCB edge.
Where both ends use D-sub connectors, select the appropriate male and female combination from the product cards. The electrical map is specified separately from those physical mating choices.
All Forty Positions Accounted For
In a 40-position IDC to 37-position D-sub assembly, the remaining three positions must have a recorded purpose. They may be unused or assigned according to the equipment circuit; there is no universal default.
A complete schedule shows the expected connections and intentional open positions. This gives engineering and inspection the same reference and avoids treating an undocumented contact as an acceptable omission.
Room Behind the D Sub
The shell, fastening hardware and first ribbon bend can occupy more space than expected from a front view of the connector. Show the panel thickness and nearby parts when the installation is tight.
We can discuss a practical cable exit and length around that space. If the route is external or needs shielding, compare the DB37 cable range as a different construction.
Yes. Keep each connection map under a separate assembly reference and list its quantity. Connector gender or cable color should not be the only way to distinguish them.
Yes. Provide the endpoint names and a visible label position. This can be useful when the cable connects different modules that are close together inside the enclosure.
We can review the mating hardware and panel drawing. Include thread, projection, and access requirements so the fastening choice is part of the assembly, not a late addition.
Yes. State the spare quantity and identification requirements in the order. Separate packing helps keep service inventory from being used up by production-line cables.
We can review the requirements for each endpoint against the mating components. The approved BOM should identify the finish at each end explicitly.
Include the assembly reference, affected quantity, and the expected versus observed connection or dimension. Photos of the installed route and any repair history help distinguish wiring, fit, and handling issues.
A proposed change can be evaluated, but matching contact count alone is not approval. Review fit, termination, and relevant performance before releasing the revised assembly.

Planning a DB37 Interconnect for a Multi-Signal System
A DB37 assembly can bring many connections into one cable, which makes a clear wiring record particularly valuable. The aim is to make the cable easier to install and diagnose, not simply to gather conductors into a common connector.
Organize the Map Around the Equipment
Identify the signals, return connections, and any shell bond from the system design. Contact count does not establish which circuits can be combined or what electrical levels are present. For a measurement connection, the conductor arrangement and surrounding noise environment deserve attention alongside continuity.
If a smaller interface is appropriate for a new design, our DB25 ribbon assemblies offer another option to consider. An existing machine should keep the interface and mapping its design requires.
Make Connector Views Unambiguous
The mating face and termination side show contact positions from different viewpoints. Name the view on the drawing and locate the reference conductor at each end. This prevents a visually neat ribbon from concealing a mirrored interpretation of the numbers.
Inspect What the Map Requires
Define continuity and short-circuit checks against the complete schedule, including the three additional IDC positions. Any shared connections or intentional opens should appear as expected results, not exceptions discovered after testing.
For the mechanical trial, use the real mating connector and hardware. A sample that fits without them may not reveal the space needed behind the shell or around the retaining screws.
Start With a Useful Reference
Send your map and route drawing if they are ready. If not, a sample, equipment model, and photos of both mating locations can begin the inquiry. We can help identify the missing cable details before you commit to a production configuration.
Include the expected quantities for engineering evaluation, service spares, or repeat production. These uses can require different packaging and identification even when the underlying cable is the same.
