DB9 Serial Female 9 Pin RS232 Cable with Bare Wire Ends - 25 ft

In this review the Compucableplususa.com DB9 Serial Female 9 Pin RS232 Cable is assessed as a practical, no-nonsense solution for connecting legacy serial devices to custom electronics or control boards. The single biggest reason to buy is straightforward: it pairs a standard DB9 female connector with labeled, tin-coated bare wire leads over a long 25 ft run, making it easier to integrate RS-232 devices without having to reterminate or use intermediary adapters. The review focuses on fit, wiring clarity, and suitability for industrial and hobbyist use.

Key Features

• DB9 female connector: Provides a standard, durable serial interface to connect legacy RS-232 equipment directly without adapters.
• 25 ft industrial grade cable: Extra length lets you route connections across workshops, control cabinets, or between devices without signal compromises typical in short jumper leads.
• Tin-coated bare wire ends: The pre-tinned wires are ready for soldering or terminal blocks and reduce the need for additional preparation when attaching to boards.
• Wire labeling with colors and pin numbers: Each lead is identified to simplify wiring and avoid mistakes when assembling or replacing connections.
• RS-232 level UART signals: Uses industry-standard signaling to ensure broad compatibility with serial devices and legacy systems.

Who It's For

The cable is best for technicians, system integrators, and hobbyists who need a dependable way to connect RS-232 devices to PCBs, PLCs, or terminal blocks without buying custom harnesses. Its labeled bare leads and generous 25 ft length suit workshop installations, industrial panels, and field equipment where routing and clear identification are important.

Those who should look elsewhere include users who require shielded, high-speed serial connections for EMI-sensitive environments or people who need a fully terminated DB9-to-DB9 cable without exposed wire ends; a ready-made DB9-to-DB9 mating cable or a certified shielded assembly would be a better fit.

Pros & Cons

Pros

• Long 25 ft length reduces the need for extension adapters and allows flexible routing in installations.
• Pre-tinned, color-coded wire ends with pin numbers save time during soldering and reduce wiring errors.
• Standard DB9 female connector ensures compatibility with a wide range of RS-232 equipment and legacy devices.
• Industry-level RS-232 signaling provides reliable UART communication for control and data links.

Cons

• Exposed bare wire ends are not ideal for environments that require fully shielded or factory-terminated cables.
• The product description does not specify overall cable shielding or jacket ratings for severe outdoor exposure.

Frequently Asked Questions

Can the bare wire ends be soldered directly to a PCB?
Yes, the tin-coated bare wires are prepared for soldering and are labeled by color and pin number to simplify PCB or terminal connections.

Is this cable shielded for EMI protection?
The description notes a black PVC jacket but does not specify internal shielding, so for EMI-sensitive applications a shielded cable or additional grounding should be used.

Will this work with standard RS-232 devices?
Yes, it carries RS-232 level UART signals and uses the industry-standard DB9 female connector for broad device compatibility.
