Technical Summary
Starway Technology manufactures tactical communication spiral cable assemblies for armored vehicle and high-reliability communication applications. This product uses an Amphenol Nexus Technologies U-329/U connector on one end and a customer-specific 8-pin DIN connector with custom strain relief on the opposite end.
The U-329/U side is wired to a 3.5mm TRRS signal assignment: Pin A connects to TRRS sleeve for GND, Pin B connects to TRRS tip for RIG_AFOUT, Pin C connects to TRRS ring 2 for PTT, and Pin D connects to TRRS ring 1 for RIG_AFIN. This mapping supports communication signal routing between the tactical connector interface and TRRS audio/control signal functions.
The cable uses a custom PU spiral cable construction for audio signal use, including power 2C in black and red plus two coaxial lines corresponding to TRRS signal paths. The 8-pin DIN side uses a customer-defined special shape and net-tail strain relief design. Based on the customer-provided STP file, Starway first supports 3D-printed prototype validation; after customer testing and approval, the project proceeds to custom mold development and 85% black PVC overmolding using a vertical injection molding machine.

Custom 8-pin DIN connector side with customer-defined shape, net-tail strain relief, adhesive preparation, and 85% black PVC overmolding.
Custom 8-Pin DIN Overmolded Strain Relief Side
The opposite connector side uses an 8-pin DIN connector with a customer-defined special shape and net-tail strain relief. The customer provides the STP file, and Starway supports 3D-printed prototype preparation so that the customer can verify connector geometry, strain relief shape, cable exit direction, fit, and handling before tooling investment.
After customer testing and approval, the project moves to custom mold development and production. Because PVC and PU materials do not bond reliably by themselves, adhesive is applied to the overmolding area before injection. The strain relief is then formed using 85% black PVC and a vertical injection molding machine to complete the custom connector assembly.
From STP Prototype Validation to Molded Strain Relief Production
For military communication cable assemblies with custom connector geometry and strain relief requirements, prototype validation before tooling helps reduce mold revision risk. Starway Technology uses customer-provided STP files to support 3D-printed prototype preparation before mold investment.
OEM Manufacturing Process Flow
IPC-based workmanship thinking is closely related to the three practical quality principles: Function, Fit, and Form. For a tactical ANR communication spiral cable assembly, this means the cable must perform electrically, fit the connector and vehicle communication system correctly, and maintain acceptable workmanship appearance after assembly.
The following OEM process flow shows how Starway Technology controls key manufacturing steps for this tactical ANR communication spiral cable assembly, from wire cutting and spiral cable processing to U-329/U connector assembly, 8-pin DIN overmolding, electrical testing, packaging, and shipment.

- Customer name, project name, product name, drawing number, revision level, BOM details, U-329/U pin assignment, TRRS mapping, and production notes are reviewed before release.
Key Process Control Points During Manufacturing
For tactical communication spiral cable assemblies, process control must cover the electrical requirements of audio and PTT signal routing, the mechanical requirements of spiral cable recovery, and the protection requirements of connector assembly and strain relief molding.

- The customer-defined net-tail strain relief shape is produced using a custom mold, 85% black PVC, and vertical injection molding equipment.
- Electrical Testing and Final Release
- Continuity testing, contact verification, insulation resistance testing, visual inspection, individual connector packaging, and production records are reviewed before shipment.
Common Manufacturing Risks for Tactical Spiral Cable Assemblies
Incorrect Signal Assignment
U-329/U to TRRS mapping errors may affect GND, audio output, PTT, or microphone/data signal function if pin assignment is not verified before final release.
Spiral Cable Length Variation
Spiral cable forming changes the final cable behavior, so both ends must be cut to the customer-specified length after spiral processing.
PU-to-PVC Bonding Risk
PVC and PU materials may not bond reliably without adhesive preparation, which can affect strain relief durability during repeated bending.
Connector Handling Damage
Military communication connectors may be damaged by collision during packaging or shipment, so individual connector protection is used to reduce handling risk.
IPC-Based Workmanship Approach
As an IPC Association member, Starway Technology applies IPC-based workmanship principles across custom wire harness and cable assembly manufacturing, including wire cutting, jacket stripping, insulation stripping, soldering preparation, connector assembly, electrical testing, packaging, and final inspection.
Relevant workmanship references may include IPC/WHMA-A-620 Chapter 3 for wire preparation and connector-related cable assembly workmanship, together with project-specific inspection principles for soldering, contact verification, strain relief assembly, and final cable assembly quality control.
These references do not replace customer drawings, Amphenol Nexus connector specifications, STP files, mold design requirements, armored vehicle communication system requirements, TRRS pin assignment, or project-specific test criteria. Instead, they provide a workmanship framework that helps strengthen inspection awareness, production control, and technical communication between the customer and manufacturer.
Customer Value
Controlled tactical cable assembly manufacturing helps customers reduce wiring assignment risk, validate special connector geometry, confirm strain relief performance, improve spiral cable handling, and support repeat production for armored vehicle communication applications. This approach is especially valuable for military communication systems, aerospace support equipment, defense electronics, armored vehicle interconnects, and other high-reliability applications where signal routing, connector protection, and mechanical durability are critical.
