Key Applications & Projects

• Smart Door Locks: Rapidly slide a deadbolt or latch mechanism (low friction, high speed).

• Animatronics & Props: create life-like, fast movements for cosplay wings, hidden compartments, or scare-pranks where slow motion ruins the effect.

• Sorting Diverters: Quickly push lightweight boxes or items off a conveyor belt.

• RC Model Landing Gear: Deploy mechanisms on large scale RC planes or boats.

Unlock New Capabilities (Project Evolution)

• Prerequisite: You've likely used Solenoids for fast motion, but found they only have a short stroke (10-20mm).

• The Upgrade: This actuator gives you the Speed of a Solenoid with the Long Reach (100mm) of an actuator. It bridges the gap between magnetic "clicks" and motorized "pushes."

• Effort Level: Intermediate. Requires careful mechanical alignment to ensure no side-load or friction exceeds the 2kg limit.

Virtual Technician: Wiring & Safety Guide ⚠️

• Friction Kills: Since the force limit is only ~2kg, any friction in your hinge or rail will stall the motor. Ensure your mechanism moves freely by hand before attaching this actuator.

• Power Supply: Use a 12V 2A Adapter. While running current is low, start-up spikes can be high due to the high-speed winding.

• Control Logic: Use a standard H-Bridge (L298N or Relay Module) to reverse polarity.

  • Red (+), Black (-): Extend

  • Red (-), Black (+): Retract

Frequently Asked Questions (FAQ)

1. Can this open a bedroom window?

   • No. A window weighs far more than 2kg (force). This motor will stall and burn out. Use the 800N version for windows.

2. Why is it so weak (19N)?

   • To get 50mm/s speed from a small motor, we use a low gear ratio. This trades Torque for Speed.

3. Can I slow it down?

   • Yes, using a PWM speed controller, but this will reduce the force even further (below 2kg).

4. Does it hold position when power is off?

   • Yes, but due to the steep thread pitch (for speed), it is easier to "back-drive" (force down) than slower actuators. It is not a strong mechanical lock.

5. What happens if I block the movement?

   • It will stall immediately. Since it moves fast, impact damage can occur. We recommend using a Current Sensor to detect stalls and cut power.

6. Is it waterproof?

   • IP54: Good for rain/splashes, but not submersion.

7. How loud is it?

   • Louder than slow actuators. The high-speed motor makes a distinct high-pitched whirring sound.

8. Can I adjust the stroke to 50mm?

   • Not internally. You must install external limit switches to stop the power earlier.

9. Will it work on 6V?

   • It will move slower (approx 25mm/s) and have very little force. Not recommended.

10. Is this compatible with Arduino?

    • Yes, via a Relay Module or L298N driver. Do not power directly from GPIO.

11. Can I use this for a pinball plunger?

    • It is fast, but probably not "instant" enough for pinball physics. Solenoids are better for impact.

12. What is the duty cycle?

    • 10%. Do not run it continuously. It needs time to cool down.

    • Probots™ LifeCycle Ready ⏳: Respecting the duty cycle is the #1 way to make this last for years.

13. Does it have a potentiometer?

    • No, this is a 2-wire motor. No position feedback.

    • Probots™ Tech-Bridge ????‍????: If you need feedback, look for our actuators with "POT" in the title.

14. What are the mounting hole dimensions?

    • 6mm diameter holes on both the motor end and rod end.

15. Can I use a 9V battery?

    • No. 9V batteries cannot supply the surge current needed for 50mm/s acceleration.

16. Why is my actuator jittering?

    • Loose connections or an under-powered supply (voltage dip) usually cause jitter at high speeds.

17. Can I use this for a cosplay Iron Man helmet?

    • Yes! This is the perfect use case. It's fast enough to look cool and strong enough to lift a plastic faceplate.

18. Does it spark?

    • Brushed motors create small internal sparks. Do not use near flammable gases.

19. How accurate is the stopping point?

    • The internal limit switches are fairly accurate, but momentum might cause it to coast 1-2mm after power cut.

20. Is the rod stainless steel?

    • It is typically aluminum alloy to save weight for higher speed.
