Sub-D cable ShiverPeaks 78021-5 — 2×25-pin, 5 m

Shielded Sub-D cable ShiverPeaks 78021-5 is a twin 25-pin D-sub connection cable with a length of 5 meters, designed for reliable signal transmission between devices that use 25-pin D-sub interfaces. The cable features two 25-pin male connectors in molded housings and an overall braided shield to reduce electromagnetic interference, ensuring stable communication for serial or parallel links in industrial, laboratory and legacy computing environments.

Advantages

The shielded construction minimizes noise and crosstalk, improving signal integrity over the full 5 m length. Molded connector housings provide mechanical strain relief and protect the contacts from damage and environmental contamination. Twin 25-pin connectors allow direct connection of devices with dual D-sub interfaces without additional adapters, simplifying installation and reducing potential points of failure.

Suitable for

• Connecting industrial controllers, PLCs and instrumentation with 25-pin D-sub ports
• Linking legacy computers, printers and parallel devices that use DB-25 interfaces
• Extending serial or parallel connections in laboratory and test setups
• Use in environments requiring improved EMI protection for data lines

Key specifications

• Cable type: shielded Sub-D (D-sub) twin 25-pin
• Connector configuration: 2 × 25-pin male (DB-25 style) in molded housings
• Length: 5.0 meters
• Shielding: braided/overall shield for EMI reduction
• Contact protection: molded strain-relief housings

How to use

Verify that both devices have compatible 25-pin D-sub ports and power down equipment if recommended by the device manufacturers before connecting. Align each 25-pin connector with the corresponding D-sub socket and secure any screws or fasteners to ensure a firm mechanical connection. After connection, power up devices and check communication status or run device-specific tests to confirm signal integrity. For removal, power down if required and unscrew the connectors before gently withdrawing the cable.

Recommendations

Avoid sharp bends and excessive tension on the cable to maintain shielding effectiveness and connector integrity; route the cable away from high-voltage lines and strong RF sources for optimal performance.
