Introduction

The Actuonix L16-P Linear Actuator (Model: L16-100-63-12-P) is a compact and versatile device designed to convert rotary motion into precise linear motion. This actuator is ideal for applications requiring accurate positioning and control, such as robotics, industrial automation, home automation, and prototyping. Its right-facing orientation provides additional flexibility for installation in tight or constrained spaces.

The L16-P model features an integrated potentiometer for position feedback, making it suitable for closed-loop control systems. With its compact size and robust design, this actuator is a reliable choice for projects requiring smooth and repeatable linear motion.

Pin Configuration

The L16-P Linear Actuator has a 3-wire interface for power, ground, and feedback. The pinout is as follows:

Wire Color Function Description
Red Power (V+) Connect to a 12 V DC power source.
Black Ground (GND) Connect to the ground of the power source.
Blue Feedback (POT) Provides position feedback as a voltage signal.

Usage Instructions

How to Use the Actuator in a Circuit

  1. Power Connection:

    • Connect the red wire to the positive terminal of a 12 V DC power supply.
    • Connect the black wire to the ground terminal of the power supply.

  2. Feedback Connection:

    • The blue wire outputs a voltage proportional to the actuator's position.
    • Connect this wire to an analog input pin of a microcontroller (e.g., Arduino) for position monitoring.

  3. Control:

    • Use an H-bridge motor driver or a DPDT switch to reverse the polarity of the power supply for bidirectional movement.
    • The actuator extends when the red wire is positive and retracts when the red wire is negative.

Important Considerations

Example: Using with Arduino UNO

Below is an example of how to control the L16-P Linear Actuator with an Arduino UNO:

// Define pin connections
const int motorPin1 = 9; // H-bridge input 1
const int motorPin2 = 10; // H-bridge input 2
const int potPin = A0; // Analog pin for potentiometer feedback

void setup() {
  // Set motor pins as outputs
  pinMode(motorPin1, OUTPUT);
  pinMode(motorPin2, OUTPUT);

  // Set up serial communication for debugging
  Serial.begin(9600);
}

void loop() {
  // Read the potentiometer feedback
  int potValue = analogRead(potPin);

  // Map the potentiometer value to a position (0-100 mm)
  float position = map(potValue, 0, 1023, 0, 100);

  // Print the position to the Serial Monitor
  Serial.print("Position: ");
  Serial.print(position);
  Serial.println(" mm");

  // Example: Extend the actuator for 2 seconds
  digitalWrite(motorPin1, HIGH);
  digitalWrite(motorPin2, LOW);
  delay(2000);

  // Example: Retract the actuator for 2 seconds
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, HIGH);
  delay(2000);

  // Stop the actuator
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, LOW);
  delay(1000);
}

Troubleshooting and FAQs

Common Issues and Solutions

  1. Actuator Does Not Move:

    • Check the power supply voltage (must be 12 V DC).
    • Verify the wiring connections, especially the polarity of the power wires.
    • Ensure the current supply is sufficient (at least 900 mA for stall conditions).

  2. Inaccurate Position Feedback:

    • Verify the connection of the blue feedback wire to the microcontroller's analog input.
    • Ensure the potentiometer's resistance range (0–10 kΩ) is correctly mapped in your code.

  3. Actuator Stalls or Overheats:

    • Avoid exceeding the maximum load of 50 N.
    • Check for obstructions or excessive friction in the actuator's path.

  4. No Feedback Signal:

    • Ensure the blue wire is not shorted or disconnected.
    • Test the potentiometer output with a multimeter to confirm functionality.
