D-SUB/RS-232-D-SUB/RS-232 30m

D‑SUB/RS‑232 Serial Extension Cable – 30 m

The 30‑meter D‑SUB/RS‑232 serial extension cable is engineered to deliver reliable, high‑quality data transmission between two devices that require a standard RS‑232 interface. Its robust construction and precise engineering make it an essential component for industrial automation, laboratory instrumentation, and any application where long‑distance serial communication is required.

Key Features

• Length: 30 meters – ideal for connecting equipment that are spaced apart in large workspaces or control rooms.
• Connector Types: Male DB‑9 on one end, Female DB‑9 on the other, ensuring compatibility with a wide range of serial devices such as PLCs, CNC machines, and legacy computer systems.
• Colour: Grey – a neutral hue that blends seamlessly into most industrial environments while providing easy visual identification among cables.
• Gender Flexibility: The cable supports both Male/Female configurations, allowing it to be used as an extension or a direct connection between two devices.
• Shielded Construction: Each twisted pair is individually shielded and the entire cable is wrapped in a protective outer sheath, minimizing electromagnetic interference (EMI) and ensuring signal integrity over long distances.

Technical Specifications

Applications

The versatility of the 30‑meter D‑SUB/RS‑232 cable makes it suitable for a wide array of settings:

• Industrial Automation: Connecting programmable logic controllers (PLCs) to supervisory control and data acquisition (SCADA) systems across factory floors.
• Laboratory Equipment: Linking spectrometers, oscilloscopes, or other serial‑controlled instruments to a central computer for data logging.
• Legacy Systems Integration: Extending the reach of older serial devices that still rely on RS‑232 interfaces in modern networks.
• Telecommunications: Providing reliable serial links between remote communication terminals and base stations.

Installation Guidelines

1. Preparation: Ensure that both devices have compatible DB‑9 ports. Verify the correct gender orientation before connecting.
2. Connection: Insert the male end into the device’s female port and the female end into the other device’s male port. Secure each connector with a gentle twist to lock it in place.
3. Cable Management: Route the cable away from high‑current power lines or sources of strong magnetic fields to reduce interference. Use cable ties or conduits where necessary.
4. Testing: After installation, perform a simple loopback test or use serial communication software to confirm data integrity and latency within acceptable limits.

Maintenance Tips

• Inspect connectors regularly for signs of wear or corrosion. Clean with a dry microfiber cloth if needed.
• Avoid sharp bends; maintain a minimum bend radius of at least 12 cm to preserve cable integrity.
• Store the cable in a cool, dry environment when not in use to prevent degradation of insulation and shielding.

Why Choose This Cable?

The combination of a generous 30‑meter length, robust shielded construction, and precise DB‑9 connectors ensures that this cable delivers consistent, low‑latency serial communication even in demanding industrial environments. Its grey colour provides unobtrusive visibility while maintaining professional aesthetics.

Conclusion

The D‑SUB/RS‑232 30 m serial extension cable is a reliable, high‑performance solution for extending RS‑232 connections across significant distances. Its thoughtful design, durable materials, and versatile connector configuration make it an indispensable tool for engineers, technicians, and system integrators who require dependable serial communication in complex setups.
