How to Use Actuonix L16-P Linear Actuator (left facing): Examples, Pinouts, and Specs

The Actuonix L16-P Linear Actuator (Part ID: L16-100-63-12-P) is a compact and versatile linear actuator designed to provide precise linear motion. This model features a left-facing design, making it ideal for applications where space constraints or specific mechanical configurations are a concern. The L16-P is equipped with a potentiometer for position feedback, enabling precise control in automation and robotics systems.

The L16-P Linear Actuator features a 6-pin JST connector for power, control, and feedback. The pinout is as follows:

1. Power Supply: Connect the red wire to a 12 V DC power source and the black wire to ground. Ensure the power supply can handle the actuator's current requirements.
2. Position Feedback: Use the potentiometer output (blue wire) to monitor the actuator's position. Connect the green wire to ground and the yellow wire to a 5 V reference voltage.
3. Control: The actuator can be controlled using an H-bridge motor driver or a microcontroller with PWM (Pulse Width Modulation) capabilities.

Below is an example of how to control the L16-P Linear Actuator using an Arduino UNO. The potentiometer feedback is used to monitor the actuator's position.

• Connect the red wire to the motor driver's output (12 V).
• Connect the black wire to the motor driver's ground.
• Connect the blue wire to an analog input pin on the Arduino (e.g., A0).
• Connect the green wire to the Arduino's GND.
• Connect the yellow wire to the Arduino's 5 V pin.

// Define pins for actuator control and feedback
const int potPin = A0; // Potentiometer feedback connected to A0
const int motorPin1 = 9; // Motor control pin 1 (PWM)
const int motorPin2 = 10; // Motor control pin 2 (PWM)

// Variables to store potentiometer readings
int potValue = 0;
int targetPosition = 512; // Target position (0-1023 for 10-bit ADC)

void setup() {
  pinMode(motorPin1, OUTPUT);
  pinMode(motorPin2, OUTPUT);
  Serial.begin(9600); // Initialize serial communication for debugging
}

void loop() {
  // Read the potentiometer value
  potValue = analogRead(potPin);
  Serial.print("Potentiometer Value: ");
  Serial.println(potValue);

  // Control the actuator to move toward the target position
  if (potValue < targetPosition - 10) {
    // Move actuator forward
    analogWrite(motorPin1, 150); // Adjust PWM value as needed
    analogWrite(motorPin2, 0);
  } else if (potValue > targetPosition + 10) {
    // Move actuator backward
    analogWrite(motorPin1, 0);
    analogWrite(motorPin2, 150); // Adjust PWM value as needed
  } else {
    // Stop the actuator
    analogWrite(motorPin1, 0);
    analogWrite(motorPin2, 0);
  }

  delay(10); // Small delay for stability
}

• Power Supply: Ensure the power supply provides sufficient current for the actuator's operation.
• Duty Cycle: Operate the actuator within its rated duty cycle (20% at full load) to prevent overheating.
• Position Feedback: Use the potentiometer feedback for precise control in closed-loop systems.
• Mounting: Securely mount the actuator to prevent misalignment or mechanical stress.

1. Actuator Does Not Move

   • Verify the power supply voltage is 12 V DC.
   • Check the motor driver connections and ensure proper control signals are being sent.
   • Ensure the actuator is not overloaded beyond its maximum force rating (63 N).

2. Inaccurate Position Feedback

   • Verify the potentiometer connections (blue, green, and yellow wires).
   • Ensure the potentiometer is powered with a stable 5 V reference voltage.
   • Check for noise or interference in the analog signal.

3. Overheating

   • Ensure the actuator is operated within its duty cycle (20% at full load).
   • Allow sufficient cooling time between operations.

4. No Feedback Signal

   • Confirm the potentiometer ground (green wire) is connected to the system ground.
   • Check the analog input pin on the microcontroller for proper configuration.

Q: Can the L16-P be used with a 24 V power supply?
A: No, the L16-P is designed for 12 V DC operation. Using a higher voltage may damage the actuator.

Q: How do I determine the actuator's position?
A: The potentiometer output (blue wire) provides an analog voltage proportional to the actuator's position. Use an ADC (Analog-to-Digital Converter) to read this value.

Q: Can the actuator be used in outdoor environments?
A: The L16-P is not rated for outdoor use. Protect it from moisture, dust, and extreme temperatures to ensure reliable operation.

Q: What is the lifespan of the actuator?
A: The lifespan depends on the operating conditions, load, and duty cycle. Proper usage and maintenance can extend its life significantly.
