High Quality 24AWG DB9 Male to Female and 12V Powered USB Cable D-SUB Splitter Cable for Security Monitoring
1. Product Introduction
DB9 Male to DB9 & Powered USB Female Cable is a multifunctional hybrid cable, mainly used for:
DB9 (RS-232) serial communication: connecting industrial equipment, POS machines, PLCs, etc.
USB power supply (5V/12V): providing additional power for peripherals (such as USB to serial adapters, small displays, etc.).
Y-type branching design: one cable meets the needs of serial communication + power supply at the same time, reducing the complexity of wiring.
Suitable for industrial automation, vehicle-mounted equipment, security monitoring, embedded development and other scenarios.
2. Product advantages
| Advantages |
Description |
| Two-in-one function |
One cable provides DB9 serial communication + USB power supply at the same time, reducing cable clutter. |
| Stable power supply |
The USB interface can provide 5V/12V power supply to avoid abnormalities of the device due to insufficient power supply. |
| Strong compatibility |
Standard DB9 (RS-232) interface, suitable for most industrial equipment. |
| Plug and play |
No additional driver is required (some USB devices may require drivers). |
| Anti-interference design |
Using shielded wire to reduce electromagnetic interference and is suitable for industrial environments. |

4. Application scenarios
- Industrial control: data communication + power supply for PLC, HMI, CNC machine tools and other equipment.
- Vehicle/marine equipment: GPS navigation, OBD diagnostic instrument, marine instrument.
- POS terminal: connect old serial printer or card reader.
- Security monitoring: serial camera, access controller power supply + data transmission.
- Embedded development: microcontroller, industrial computer debugging power supply.
5. Purchase suggestions
Interface matching: confirm whether the device requires DB9 male or female (this line is DB9 Male to DB9 Female).
Power supply requirements: check the USB interface voltage (5V or 12V) to avoid device incompatibility.
Cable length: 1~3 meters is recommended for industrial applications. Too long may cause signal attenuation.
Shielding performance: double-layer shielded cable is preferred to reduce electromagnetic interference.
6. Safety precautions
Avoid overload: The maximum current of USB power supply is usually 2A, and overload may damage the device.
Anti-short circuit: Make sure the DB9 interface is correctly connected to avoid short circuit of pins.
Waterproof and dustproof: It is recommended to use protective sleeves in industrial environments.
Regular inspection: Long-term bending may cause the wire to break, and regular maintenance is required.
7. FAQ (Frequently Asked Questions)
Q1: Can this cable be used for USB 3.0 devices?
A: No, it only provides 5V/12V power supply and does not include USB 3.0 data transmission function.
Q2: Does the DB9 interface support RS-485?
A: No, it is only applicable to RS-232 standard devices. If RS-485 is required, an additional converter is required.
Q3: Can only the DB9 part be used without USB power supply?
A: Yes, USB power supply is an optional function and does not affect DB9 communication.
Q4: How many meters can the cable support?
A: The RS-232 standard recommends not more than 15 meters. Too long may cause signal loss.
8. Summary
DB9 Male to DB9 & Powered USB Female Cable is a multifunctional cable suitable for industrial, automotive and embedded systems, integrating serial communication + power supply functions to reduce the complexity of equipment wiring. When purchasing, pay attention to the interface type, power supply requirements and cable quality to ensure stable operation.
1. PVC environmentally friendly high-flexible wire tensile shield: 10,000 swing tests, 72-hour aging tests, 4-30KG tensile tests have a longer service life and always maintain flexibility under the protection of a strong outer jacket.
2. Multiple shielding and high-speed transmission: thickened tinned copper core, plus aluminum foil metal shielding braided mesh, multiple shielding and anti-interference, serial communication data transmission in seconds.
3. Gold-plated contacts: anti-oxidation and anti-corrosion, internal gold-plated contact welding optimizes the transmission channel
Using thickened oxygen free copper wire core effectively reduces resistance and makes the circuit less prone to overheating. Simultaneously coated with a fireproof layer, it remains safe and durable even in high-temperature and dry environments. Bold thread body, sturdy and resistant to bending, will not break after long-term use.
