Servo Extension Cable 30cm Male to Female Wire (JR/Futaba Compatible)

Specifications:

• Length: 300mm (30cm)
  
• Connector Type: 3-Pin JR / Futaba Compatible
  
• Gender: Male to Female
  
• Wire Gauge: 26 AWG High-Flex
  
• Interface: 2.54mm Pitch

Key Applications & Projects

• Fixed-Wing RC Planes: Extending aileron and flap servos from the wings to the central receiver.
  
• Robotic Arms: Routing wires through joints where standard leads cannot reach.
  
• Drones & UAVs: Connecting gimbal controllers to the flight controller across the frame.
  Bipedal Robots: Managing cable slack in leg actuators for fluid movement.

Project Evolution 

• Past Projects (Prerequisites): If you have built small desktop robots with 20cm extensions, you likely found the wiring reached its physical limit quickly.
  
• Feature Upgrade: This 30cm extension unlocks "Large-Format Integration." It allows for decentralized control systems where the brain (microcontroller) can be centrally located while actuators are placed at the extremities of a larger chassis.
  
• Effort/Requirements: Beginner Level. No soldering required. Simply plug and play. At 30cm, we recommend using a capacitor near the servo if using high-torque motors to prevent voltage ripples.

Virtual Technician & Wiring

Safety Warning: Ensure the brown (GND) wire is aligned across the entire chain. Reversing the polarity on a 30cm run can cause significant heat buildup in the thin 26AWG wire.

Wiring Guide:

• Black/Brown: Ground (0V)
• Red: Power (4.8V - 7.2V)
• White/Orange: PWM Signal

Frequently Asked Questions (FAQ)

1. Is this cable compatible with SG90 servos?
   Yes, it uses the standard 2.54mm 3-pin connector used by SG90 and MG996R.
2. Can I daisy-chain multiple extensions?
   Yes, but be mindful of voltage drop over very long distances.
3. Does it work with Futaba receivers?
   Yes, the "universal" JR style fits both JR and Futaba (with the small tab removed if necessary).
4. What is the current rating for this wire?
   It safely handles up to 2A, suitable for most standard and high-torque servos.
5. Will this fit into a standard breadboard?
   The male end can be inserted into a breadboard, though it is designed for mating with female servo plugs.
6. Are the wires braided or flat?
   These are standard flat-ribbon style for easy routing.
7. Can I use this for digital servos?
   Absolutely, it carries PWM signals for both analog and digital servos.
8. What happens if I plug it in backward?
   The keyed connector prevents this, but a reversed connection usually just results in the servo not moving.
9. Is the wire flexible enough for robotic joints?
   Yes, the high-strand copper allows for frequent bending.
10. Does the 30cm length include the connectors?
    Yes, the total length from tip to tip is 30cm.
11. Can this be used for sensors?
    Yes, many 3-pin sensors (like IR or Ultrasonic) use the same pinout.
12. Is it 3.3V logic compatible?
    Yes, the cable is passive and works with 3.3V or 5V logic.
13. Is the insulation fire-retardant?
    It features standard electrical-grade PVC insulation.
14. How do I secure the connection so it doesn't pull apart?
    We recommend using a clip or heat-shrink tubing for high-vibration environments.
15. What is the weight of the cable?
    Approximately 10 grams.
16. Can I use this for high-voltage (7.4V) servos?
    Yes, the insulation is rated for standard RC voltages.
17. Is this JR or Futaba style?
    It is a "Universal" style that works with both.
18. Why is the signal wire orange instead of white?
    This follows the Futaba color convention; white is the signal wire.
19. Does this cable reduce servo speed?
    No, the resistance over 30cm is negligible for standard servos.
20. Is this available in bulk for schools?
    Yes, please contact Probots support for institutional pricing.
