DB9 RS232 Serial Cable with Bare Wire Ends - 35 ft Industrial Grade

In this review of the DB9 RS232 Serial Cable with bare wire ends, the bottom line is simple: it is a practical, industrial-grade solution for connecting legacy RS-232 devices to custom boards or equipment. The reviewer found the 35 ft length and individually color-coded, pin-labeled wire leads make assembly and troubleshooting far easier than typical generic serial cables. For technicians, installers, and equipment integrators who need a long, shielded male DB9 lead with clear soldering points and dependable RS-232 signaling, this cable delivers solid value without unnecessary extras.

Key Features

• 35 ft length: Provides ample reach for installations across factory floors or between racks without relying on adapters or repeaters.
• Bare wire ends labeled by pin: Each conductor is color coded and labeled with its DB9 pin number, simplifying wiring and reducing errors during assembly.
• Male DB9 molded plug with thumb screws: The molded connector and slotted thumb screws secure the connection and can be tightened with a screwdriver in tight spaces.
• Shielded cable with black PVC jacket: The braided shielding and PVC jacket help protect RS-232 level UART signals from interference in industrial environments.
• Tin-coated 28 AWG conductors: The tin coating eases soldering and improves corrosion resistance for long-term field serviceability.
• RoHS compliant: Manufactured to reduce hazardous substances, suitable for controlled electronics production environments.

Who It's For

This cable is aimed at maintenance technicians, control system integrators, and hobbyists who need to connect legacy RS-232 devices directly to terminal blocks or PCBs. The labeled, color-coded bare leads cut down on time spent tracing signals and provide clear points for soldering or screw-terminal connections.

It is less appropriate for users who want plug-and-play with both ends terminated as DB9 connectors or who require custom shielding or braided outer jackets beyond a standard PVC jacket. For short desktop use where cable length under 6 ft is enough, a shorter pre-terminated serial cable might be more convenient.

Pros & Cons

Pros

• Long 35 ft reach suits industrial and rack installations where distance is a concern.
• Individually color-coded and pin-labeled bare wires speed up assembly and reduce wiring mistakes.
• Shielded construction and molded male DB9 with thumb screws provide a secure, reliable connection.
• Tin-coated 28 AWG conductors simplify soldering and resist corrosion over time.

Cons

• One end has bare wire leads only, so users needing two DB9 connectors will require an additional adapter or termination step.
• The PVC jacket is robust but not specialized for harsh chemical or extreme temperature environments.

Our Verdict

The DB9 RS232 cable with bare wire ends is a reliable, no-nonsense choice for anyone wiring legacy serial hardware into control systems or custom electronics. Its 35 ft length, clear pin labeling, and solder-friendly tin-coated wires make it good value for technicians and integrators who prioritize ease of installation and long reach over dual-terminated convenience.

Frequently Asked Questions

Can this cable be used to connect serial devices to a PCB?
Yes. The bare, color-coded, pin-labeled leads are designed for soldering or attaching to screw terminals on PCBs and custom hardware.

Does it support true RS-232 voltage levels?
Yes. The cable is intended for RS-232 level UART signals and connects standard DB9 serial devices accordingly.

Is the cable shielded and suitable for industrial environments?
It is shielded and comes with a durable black PVC jacket, which provides good protection in typical industrial settings but not specialized extreme-environment protection.
