Sub-D Cable ShiverPeaks 78020-3 2 × 25-pin, 3 m length

The Sub-D Cable ShiverPeaks 78020-3 is a 3 m data connection cable fitted with two 25-pin D-sub (Sub-D) male connectors. It is intended for connecting devices that use the 25-pin D-sub interface for serial, parallel or mixed-signal wiring. The cable is designed to carry standard D-sub signal assignments and provides a fixed-length, shielded link between instrumentation, industrial controllers, legacy computer ports and peripheral equipment that require a 25-pin Sub-D connection.

Advantages

The cable offers a robust mechanical connection with secure snaps on the connector hoods and reliable electrical contact for all 25 pins. Its 3 m length balances reach and signal integrity for typical workstation and equipment-rack layouts. The shielded assembly reduces susceptibility to electromagnetic interference in industrial or laboratory settings, and the standardized D-sub pinout ensures compatibility with devices that follow common 25-pin wiring conventions.

Suitable for

• Connecting measurement instruments and data loggers with 25-pin D-sub ports
• Linking industrial controllers, PLCs and interface modules
• Connecting legacy computers, printers or parallel interfaces that use Sub-D 25 connectors
• Establishing serial or parallel device-to-device links in test benches and workshops

Key specifications

• Connector type: 2 × 25-pin D-sub (male)
• Cable length: 3.0 m
• Shielding: overall shield for reduced EMI
• Contact count: 25 conductors per connector
• Connector hood: snap-style fastening for secure mechanical retention
• Cable use: data and signal transmission for serial/parallel interfaces

How to use

Route the cable between the two devices ensuring that connectors align with the 25-pin D-sub ports. Attach each connector by engaging the snap hood until the connector is held firmly; avoid excessive torque on the connector housing. Ensure both devices are powered off or set to a safe state before connecting or disconnecting to prevent signal transients. Check that the connected devices share the expected signal wiring or pinout conventions before use to avoid miswired connections.

Recommendations

For reliable operation, keep cable runs away from high-power mains and motor cabling where possible, and avoid sharp bends or pinch points. When used in industrial or noisy electromagnetic environments, verify shield termination at the equipment ends. Periodically inspect connector hoods and contacts for wear or corrosion and replace the cable if physical damage or intermittent connections appear.
