Servo Extension Cable 50cm Male to Female Wire (JR/Futaba Compatible)

Specifications:

• Length: 500mm (50cm)
  
• Connector Type: 3-Pin JR / Futaba Compatible
  
• Gender: Male to Female
  
• Wire Gauge: 26 AWG High-Flex
  
• Interface: 2.54mm Pitch
  
• Color Code: Black(Ground), Red (VCC), White(Signal)
  
• Insulation: Heat-resistant PVC

Key Applications & Projects

• Giant Scale RC Planes: Essential for connecting tail-mounted rudder and elevator servos to the central receiver.
  
• Large Bipedal Robots: Ideal for routing signals from the hip-mounted controller down to the ankle actuators.
  
• Agricultural Drones: Providing the reach needed for spray-nozzle control servos on wide foldable arms.
  
• Smart Home Automation: Extending connections for window actuators or hidden camera pan-tilt units across architectural features.

Project Evolution 

• Past Projects (Prerequisites): If you've previously built desktop-sized projects using 20cm leads, you likely felt "tethered" to your controller.
  
• Feature Upgrade: This 50cm extension unlocks "Wide-Format Integration." It allows your electronics to be completely centralized in a protected enclosure while your mechanical actuators operate half a meter away.
  
• Effort/Requirements: Beginner Level. While it is plug-and-play, at this length, we recommend using a 470µF capacitor at the servo end if you are using high-torque motors to buffer any transient voltage drops.

Virtual Technician & Wiring

Safety Warning: Long cables can act as antennas for EMI (Electromagnetic Interference). Avoid routing this 50cm cable directly alongside high-current ESC battery wires to prevent signal noise.

Wiring Guide:

• Black/Brown: Connect to GND (0V).
  
• Red: Connect to VCC (4.8V - 7.4V).
  
• White/Orange: Connect to PWM Signal Pin.

1 X Servo Extension Cable 50cm Male to Female Wire (JR/Futaba Compatible)

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 50cm length include the connectors?
    Yes, the total length from tip to tip is 50cm.
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 50cm is negligible for standard servos.
20. Is this available in bulk for schools?
    Yes, please contact Probots support for institutional pricing.
