How to Use DOUBLE SOLENOID: Examples, Pinouts, and Specs

The Double Solenoid by FESTO (Manufacturer Part ID: DOUBLE SOLENOID) is an electromechanical device equipped with two coils. These coils can move a plunger or armature in two directions, making it ideal for controlling the flow of fluids or gases in various systems. Double solenoids are commonly used in automation, pneumatic systems, and hydraulic systems to achieve precise control over fluid or gas flow.

To use the double solenoid in a circuit, follow these steps:

1. Power Supply: Ensure you have a 24V DC power supply capable of providing at least 1A of current.
2. Connections:
   • Connect Pin 1 to the positive terminal of the power supply for Coil A.
   • Connect Pin 2 to the negative terminal of the power supply for Coil A.
   • Connect Pin 3 to the positive terminal of the power supply for Coil B.
   • Connect Pin 4 to the negative terminal of the power supply for Coil B.
   • Connect Pin 5 to the common ground of your circuit.
3. Control: Use a microcontroller or relay to control the activation of each coil. Activating Coil A will move the plunger in one direction, while activating Coil B will move it in the opposite direction.

• Power Supply: Ensure the power supply is stable and within the specified voltage range to avoid damaging the solenoid.
• Heat Dissipation: Double solenoids can generate heat during operation. Ensure proper ventilation or heat dissipation mechanisms are in place.
• Duty Cycle: Although the solenoid is rated for 100% duty cycle, avoid continuous activation for extended periods to prolong the lifespan of the coils.
• Debouncing: When using a microcontroller, implement debouncing techniques to avoid rapid switching that can cause wear and tear.

Below is an example code to control the double solenoid using an Arduino UNO:

// Define pin connections
const int coilAPin = 8; // Pin connected to Coil A
const int coilBPin = 9; // Pin connected to Coil B

void setup() {
  // Set pin modes
  pinMode(coilAPin, OUTPUT);
  pinMode(coilBPin, OUTPUT);
}

void loop() {
  // Activate Coil A
  digitalWrite(coilAPin, HIGH);
  delay(1000); // Keep Coil A activated for 1 second

  // Deactivate Coil A
  digitalWrite(coilAPin, LOW);
  delay(500); // Wait for 0.5 seconds

  // Activate Coil B
  digitalWrite(coilBPin, HIGH);
  delay(1000); // Keep Coil B activated for 1 second

  // Deactivate Coil B
  digitalWrite(coilBPin, LOW);
  delay(500); // Wait for 0.5 seconds
}

1. Solenoid Not Activating:

   • Solution: Check the power supply voltage and current. Ensure connections are secure and correct.

2. Overheating:

   • Solution: Ensure proper ventilation and avoid continuous activation for extended periods.

3. Erratic Behavior:

   • Solution: Implement debouncing in your control logic to avoid rapid switching.

• Check Connections: Ensure all connections are secure and correctly configured according to the pin configuration table.
• Measure Voltage and Current: Use a multimeter to verify that the solenoid is receiving the correct voltage and current.
• Inspect for Damage: Check the solenoid and wiring for any signs of physical damage or wear.
