Flat Ribbon Cable 100ft Roll - 34 Pin - 34 conductors - FRC Computer Cable
Flat Ribbon Cable 100ft Roll - 34 Pin - 34 conductors - FRC Computer Cable
The Flat Ribbon Cable 100ft Roll is a professional-grade FRC (Flat Ribbon Conductor) cable featuring 34 parallel conductors designed for high-density data transmission and signal distribution in computer systems, industrial control panels, and legacy peripheral connections. This cable is extensively used by electronics technicians, system integrators, and industrial automation professionals who require reliable multi-conductor connections with minimal crosstalk and electromagnetic interference. It solves the critical problem of managing multiple signal lines in confined spaces while maintaining signal integrity and reducing installation complexity compared to individual twisted-pair cables.
Product Overview
The Flat Ribbon Cable operates on the principle of parallel conductor arrangement where 34 individual insulated copper conductors are laminated together in a flat configuration, allowing for simultaneous transmission of multiple independent signals or data streams. This design enables efficient space utilization in equipment cabinets and control systems while maintaining proper impedance characteristics. The flat profile allows for easy routing through tight spaces, cable trays, and connector assemblies without the bulk associated with round multi-conductor cables. The 100-foot roll length provides sufficient cable for medium to large-scale installations without requiring splicing, which would compromise signal quality and reliability.
The FRC construction method involves precision manufacturing where each conductor is individually insulated with PVC or polyethylene material, then bonded together under controlled pressure to create a unified, flexible cable structure. This manufacturing process ensures consistent conductor spacing of typically 0.05 inches (1.27mm), which is critical for maintaining proper electrical characteristics and preventing signal degradation. The cable exhibits excellent flexibility despite its multi-conductor design, making it suitable for applications requiring frequent flexing or routing through conduits. The 34-pin configuration is particularly valuable for interfacing with legacy computer systems, parallel port devices, SCSI connections, and industrial equipment that utilize standard 34-pin connectors.

How to Use
Begin by identifying the connector types required at both ends of your installation. The 34-conductor ribbon cable must terminate with appropriate 34-pin connectors such as IDC (Insulation Displacement Connector) headers, D-sub connectors, or specialized industrial connectors matching your equipment specifications. Measure the required cable length carefully, accounting for routing paths, slack for maintenance access, and bend radius requirements. When installing, ensure the cable follows the minimum bend radius of 0.5 inches to prevent conductor damage and signal integrity issues. Route the cable away from high-voltage power lines, AC mains, and sources of electromagnetic interference. If routing through metal conduits, ensure proper grounding of the conduit to prevent EMI coupling into the signal conductors.
For termination, use a ribbon cable crimping tool or IDC connector insertion tool to properly seat the cable into connectors, ensuring all 34 conductors make reliable contact without damage. Verify correct pin alignment by comparing the cable orientation with your equipment documentation, as reversed polarity can damage connected devices. After installation, perform continuity testing across all 34 conductors using a multimeter to confirm proper termination and identify any broken or shorted conductors. Label both ends of the cable with conductor numbering or signal identification for future maintenance and troubleshooting. Secure the cable using cable clips or ties at regular intervals, typically every 12-18 inches, to prevent sagging and mechanical stress on connectors. Avoid excessive tension when securing, as over-tightening can damage the cable insulation and degrade signal quality.
Frequently Asked Questions
What is the difference between 34-pin ribbon cable and individual twisted-pair cables?
Ribbon cables provide a unified, space-efficient solution where 34 conductors are laminated together in a flat structure, whereas individual twisted-pair cables require separate routing and management of 17 pairs. Ribbon cables occupy significantly less space in cable trays and equipment cabinets, simplify installation by eliminating the need to manage 34 individual cables, and reduce connector complexity. However, individual twisted-pair cables offer superior EMI rejection due to the twisting geometry, making them preferable for high-noise environments. Ribbon cables are ideal for legacy systems, industrial control applications, and installations where space efficiency and cost-effectiveness are primary concerns.
Can I use this 34-pin ribbon cable with modern USB or Ethernet devices?
No, the 34-pin ribbon cable is designed specifically for legacy systems and equipment utilizing 34-pin connectors. Modern devices use USB, Ethernet, or other contemporary standards that require different cable types and connectors. Attempting to adapt this cable to modern devices would require specialized converters or adapters that may introduce signal degradation and reliability issues. If you need to interface legacy equipment with modern systems, consult with a systems integrator to determine appropriate conversion solutions that maintain signal integrity.
What is the maximum transmission speed and frequency for this ribbon cable?
The 34-pin ribbon cable is rated for parallel data transmission at speeds typically up to 2-5 Mbps depending on cable quality, conductor gauge, and termination quality. The frequency response extends to approximately 10 MHz for reliable signal transmission. These specifications are suitable for legacy parallel port devices, SCSI connections, and industrial control signals. For high-speed digital applications exceeding 10 MHz, twisted-pair or shielded cables with controlled impedance characteristics are recommended. The 300V voltage rating ensures safety in standard industrial and computer environments but should not be used in high-voltage applications exceeding this specification.
Is this ribbon cable shielded against electromagnetic interference?
Standard 34-pin ribbon cables are typically unshielded, relying on the individual insulation of each conductor to prevent cross-talk between adjacent conductors. If your application requires protection against external electromagnetic interference from power lines, motors, or RF sources, specify a shielded ribbon cable variant with an outer foil or braid shield that must be properly grounded at both ends. The 0.05-inch conductor spacing in standard ribbon cables provides reasonable cross-talk performance in typical industrial environments, but shielded versions are recommended for noise-sensitive applications such as precision measurement systems or medical equipment operating in electrically noisy facilities.
Can I cut and re-terminate this 100-foot roll to custom lengths?
Yes, the 100-foot roll can be cut to custom lengths using a sharp utility knife or ribbon cable cutter, ensuring clean cuts perpendicular to the cable length. After cutting, each end must be properly terminated with appropriate 34-pin connectors using an IDC crimping tool or connector insertion tool. Improper termination can result in loose conductors, short circuits, or signal integrity issues. We recommend having professional termination performed by experienced technicians if you lack the specialized crimping tools and expertise. Each termination must be verified using continuity testing before connecting to equipment to prevent damage from miswired connections.
