Sub-D Extension Cable ShiverPeaks 78047-3 — 15-pin, 3 m

Sub-D Extension Cable ShiverPeaks 78047-3 — 15-pin, 3 m is a 3.0 metre Sub-D (D-sub) extension cable with a 15-pin male-to-female connection that extends RS-232 and compatible analog Sub-D links while preserving original pin mapping. The cable is intended for use where a longer physical connection is required between devices that use a 15-pin connector, such as industrial controllers, measurement instruments, CNC systems and computer peripherals. The design focuses on maintaining signal continuity for serial and parallel applications and on reliable mechanical connection.

Advantages

This Sub-D extension cable provides a full 15-pin connection without altering pin assignments, enabling straightforward extension of existing cables and equipment. The molded housings at each connector improve strain relief and resist mechanical wear. With a 3.0 m length, the cable offers flexibility in equipment placement while keeping signal paths direct. The cable supports common RS-232/analog uses and is built for repeated mating cycles typical in industrial and lab environments.

Suitable for

• Extending RS-232 serial connections between computers, controllers and instruments
• Connecting CNC controllers to remote operator panels or I/O modules
• Linking measurement and test equipment that use 15-pin D-sub interfaces
• Extending joystick or control panel leads in industrial consoles

Key specifications

• Connector type: 15-pin Sub-D (D-sub) male to 15-pin Sub-D female
• Cable length: 3.0 metres
• Housing: molded connector housings for strain relief
• Signal compatibility: RS-232 and analog D-sub pin mapping preserved
• Application environment: suitable for industrial and laboratory equipment

How to use

Align the male and female 15-pin Sub-D connectors and secure the connectors using the fastening screws or thumbscrews provided on the mating connector. Ensure pins line up before applying pressure to avoid bending pins. Use the extension cable in-line between the device and its existing cable or directly between two devices with matching 15-pin D-sub ports. Avoid sharp bends near the connectors and route the cable to minimize mechanical stress and interference from high-power lines.

Recommendations

For reliable operation, check that connected devices share the same signal standard (for example RS-232) and that pin functions match. Keep the cable away from high-voltage or high-current power cables to reduce the risk of interference. Inspect connectors periodically for bent pins or housing damage and replace the cable if wear could compromise connections.
