EXSYS καλώδιο FireWire 1394B 9 σε 4 Pin, 3,0 m (EX-K6872)

When your FireWire 800 host needs to talk to a legacy FireWire 400 device, most cables force you to compromise—adapters, hubs, or worse, replacing perfectly good peripherals. The EXSYS EX-K6872 eliminates that friction with a direct 9-pin to 4-pin connection, built to the IEEE 1394b standard and ready for 800 Mbps throughput on the 9-pin side. Unlike generic cables that skimp on shielding, this one wraps its copper conductors in a double layer of foil and braid, so your data stays clean even in electrically noisy environments. At 3 meters, it gives you the reach to position devices where they actually belong, not where the cable dictates.

Highlights

• Direct FireWire 800 (9-pin) to FireWire 400 (4-pin) connection—no adapter needed
• Supports data rates up to 800 Mbps on the 9-pin side, 400 Mbps on the 4-pin side
• Double shielded (foil + braid) to minimize interference and ensure reliable transfers
• Gold-plated connectors resist corrosion and maintain signal integrity over time
• Hot-plug capable: connect and disconnect without powering down your equipment
• 3-meter length provides flexibility for desktop or rack setups

In daily use

Picture this: you have a FireWire 800 PCIe card in your workstation, but your external drive or audio interface still uses the older 4-pin FireWire 400 port. With the EX-K6872, you simply plug the 9-pin end into your computer and the 4-pin end into the device—Windows, macOS, or Linux will recognize it immediately. The cable’s robust PVC jacket shrugs off bends and foot traffic, while the gold-plated contacts ensure a snug, low-resistance connection every time. Whether you’re capturing DV footage from a camcorder or backing up to an external enclosure, this cable keeps the pipeline open and stable.
