Custom 68 Pin SCSI Cable Assemblies
“68 pin SCSI cable” narrows the search, but it still describes several physically different products. You can’t select an external HPDB68 cable, a compact VHDCI68 cable, or an internal 68-position ribbon harness by contact count alone. Gender, retention, bus type, and pinout all matter.
We manufacture these formats to approved specifications and help you identify which one your system needs. If you are maintaining a legacy array, industrial computer, or test platform, send the equipment models, port photos, and existing cable information. We will organize the details before confirming the construction. Our SCSI cable collection provides a wider family overview when the existing cable name is uncertain.

HPDB68 External Cable
- HPDB68 cable family with hood and retention options.
- Suitable when the mating ports are confirmed to be HPDB68. Specify gender, screws or clips, hood material, length, and signal class.
VHDCI68 External Cable
- Compact VHDCI68 cable family.
- The compact connector requires careful confirmation of gender, screw hardware, adjacent-port clearance, and the second-end interface.
HPDB68 Ribbon and Extension Options
- 68-position ribbon, male-to-male arrangement.
- 68-position ribbon/extension, male-to-female arrangement.
- The harness drawing should show connector orientation, keying, spacing, and pin-1 stripe direction.
Count the Contacts, Then Identify the Connector Family
The words “68 pin” do not distinguish between HPDB, VHDCI, and IDC. Send one straight-on photo and one side photo of each port. We’ll confirm the mechanical family before discussing cable construction.
Record SE, LVD or HVD
Don’t mix these signaling classes casually. Check the controller and device documentation and include the results in the purchase specification. If the information is unavailable, flag it as unresolved rather than assuming compatibility.
One Drawing for Purchasing, Production and Service
A useful drawing shows connector faces, gender, retention, length reference, pin map, and end labels. It gives purchasing a clear description, production a testable requirement, and service technicians a dependable replacement reference.
What We Need to Identify Your 68-Pin Cable
Send a straight-on photograph of each equipment port, a side view showing the locking hardware, the device model numbers, and a photograph of the complete existing cable. Confirm whether the connection is external or internal and whether the documentation identifies SE, LVD, or HVD signaling. Add the required length, quantity, and any customer part number.
When the port is a compact 0.8 mm interface, review the VHDCI Cable options. For connections inside a chassis, the SCSI Ribbon Cable page explains the additional spacing and orientation information needed for an internal harness.
No. HPDB68, VHDCI68, and IDC68 are different mechanical formats.
Only with a correctly designed mixed-interface assembly and compatible equipment. The connectors do not mate directly.
Identical-looking connectors can be used with electrically different systems. The cable must be specified for the actual bus.
Yes. Provide the connector order, spacing, orientation, keying, and the required termination arrangement.
Yes. Directional labels help when the wiring or connector genders aren’t symmetrical.
Custom projects can be planned with sample confirmation before the main lot, subject to the agreed order process.
Send a front view of each port, a side view showing retention and clearance, equipment labels, and the full existing cable.
Yes. List each connector combination, length, drawing, and quantity as a separate line item.
Yes. Provide the exact label wording and show its position on the drawing.
Use the customer or supplier part number together with the latest approved drawing revision. Do not rely only on the equipment nickname.
Request only the records your project needs, such as drawing revisions, inspection results, or relevant material declarations. Confirm availability during the quotation.
How to Build a Complete 68-Pin SCSI Cable Specification
Many wrong-cable orders begin with accurate but incomplete information. “68 pin” may be true, yet it omits the choices that decide whether the assembly can be installed and operated.
Choose HPDB68, VHDCI68 or IDC68
HPDB68 is a half-pitch external connector, VHDCI68 is a more compact high-density interface, and IDC68 is commonly used on internal ribbon assemblies. They belong to different mechanical families. Name the connector at each end rather than using only the contact count.
State Gender From the Mating Face
Shell appearance can be confusing in photographs. Identify whether each cable connector must have pins or sockets and include a mating-face image. For extensions, confirm which end is male and which is female.
Document the Bus Type
SE, LVD, and HVD describe electrical behavior, not simply connector shape. Use labels, manuals, and controller documentation to establish the system type. If several devices share the bus, review the complete chain.
Define Internal Harness Geometry
For ribbon assemblies, list every connector in order, its centerline position, orientation, and pin-1 direction. A correct pinout with one reversed IDC connector is still an unusable harness. Include bend and routing constraints if the assembly fits a compact chassis.
Keep Adapter Cables Honest
A cable with two different connectors changes the mechanical interface; it does not necessarily convert signaling or protocols. Build cross-family assemblies only when the equipment documentation provides a valid wiring relationship.
The most useful request is not the longest. A small package with port photos, equipment models, connector names, bus type, pin map, length, and quantity gives us enough context to respond responsibly and efficiently.
Review Adapter Cables at Both Ends
For HPDB68-to-VHDCI68 assemblies, check more than the cable connectors. Confirm the controller, peripheral, gender, and retaining hardware at each device. Show whether the pin map is straight, reordered, or equipment-specific. If a passive cable cannot provide the required electrical compatibility, changing the connector shell will not solve the system problem.
Define Acceptance Before the First Sample
A first article should mate without force, lock securely, route within the available space, and operate in the intended system. If the cable is directional, confirm the end labels. Record the approved drawing revision and any system-test result that your team uses for acceptance. This creates a much stronger reorder reference than a photograph alone.
Keep Variants Separate in Purchasing Records
HPDB68, VHDCI68, and IDC68 products should not share one vague description in your ERP system. Give each connector combination, length, and pinout a unique part number. If you stock service spares, include the equipment name and revision on the package label. Our quality control process can help your team decide which inspection records to include with production orders.
Use a Configuration Matrix for Multi-Cable Projects
When a machine or storage system uses several 68-position assemblies, create a short matrix with columns for customer part number, connector A, connector B, gender, retention, signaling, length, drawing revision, and quantity. The matrix exposes missing information before quotation and prevents two visually similar cables from being merged into one item. It also gives receiving and maintenance teams a simple index without replacing the detailed drawings.
Separate Mechanical and Electrical Approval
Mechanical approval confirms that the plug mates, locks, and routes correctly. Electrical approval confirms that the cable belongs on that bus and follows the authorized pin map. Both are necessary, especially for HPDB-to-VHDCI designs. Record who approves each part of the specification so a connector change is not mistaken for permission to change signaling or topology.
