Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Bidirectional Data/Power Transfer: Enables direct communication between two devices (e.g., computers, printers, modems) without requiring external modems, supporting both data transmission and power supply.
  • Twisted Pair Design: Utilizes copper conductors in a twisted pair configuration to minimize signal interference and ensure reliable performance in serial or parallel applications.

Key features

  • 1. Material Technology: Copper Conductors for Enhanced Durability and Conductivity

    • With copper conductors and a durable PVC jacket, you can ensure reliable conductivity and longevity even in frequent use. ~20% more durable than standard cables*

  • 2. Interactive Design: Bidirectional DB9 Connectors for Versatile Connectivity

    • With bidirectional DB9 connectors, you can connect devices seamlessly for data transfer and power supply without needing multiple cables. Ideal for setups requiring dual functionality.

  • 3. Performance Parameters: Twisted Pair Construction for Reduced Interference

    • With twisted pair construction, you can minimize signal interference, ensuring stable data transmission over longer distances compared to non-twisted cables.

  • 4. Scenario Solutions: Customizable Lengths for Flexible Setup Adaptation

    • With customizable lengths (1m, 1.5m, or custom), you can adapt to various computer setups, from compact workspaces to larger configurations, optimizing space utilization.

  • 5. Scenario Solutions: Coiled Design for Space-Saving and Tangle-Free Use

    • With a coiled design, you can save space and reduce tangling in cluttered workspaces, maintaining cable organization during frequent use.

Product details

DB9 Male to DB9 Female Null Modem Cable Home Theater Application Bare Copper Conductor with Braid Shielding
