How to Use Push Pull Solenoid: Examples, Pinouts, and Specs
Design with Push Pull Solenoid in Cirkit DesignerIntroduction
A push-pull solenoid is an electromechanical device designed to convert electrical energy into linear motion. It is widely used in various applications such as vending machines, locking mechanisms, robotics, and industrial equipment. The solenoid can either push or pull an object, depending on the polarity of the current applied to its coil, making it a versatile component for motion control systems.

Arduino-Controlled Multi-Solenoid Actuation System
This circuit is designed to control multiple push-pull solenoids using an Arduino UNO. Each solenoid is switched by a pMOS transistor, with a flyback diode for protection against inductive spikes. The Arduino's digital output pins are used to operate the transistors, but the control code for the Arduino is not yet provided.

This circuit uses an ESP32 microcontroller to control a 12V pneumatic solenoid valve via an IRFZ44N MOSFET as a switch. The ESP32 outputs a control signal through a 220-ohm resistor to the gate of the MOSFET, which in turn controls the power to the solenoid valve from a 12V power supply. A 10k-ohm resistor provides a pull-down for the MOSFET gate to ensure it remains off when not driven by the ESP32.

Usage Instructions
Integration into a Circuit
- Power Supply: Ensure that the power supply matches the voltage rating of the solenoid.
- Driving Circuit: Use a transistor, relay, or MOSFET to control the high current required by the solenoid.
- Diode: Place a flyback diode across the solenoid coil to protect the driving circuit from voltage spikes.
Best Practices
- Duty Cycle: Adhere to the recommended duty cycle to prevent overheating.
- Mounting: Secure the solenoid firmly to prevent movement and noise.
- Activation Time: Limit the activation time to the manufacturer's specifications.
Example Arduino UNO Code
// Define the solenoid control pin
const int solenoidPin = 7;
void setup() {
// Set the solenoid pin as an output
pinMode(solenoidPin, OUTPUT);
}
void loop() {
// Activate the solenoid
digitalWrite(solenoidPin, HIGH);
delay(1000); // Keep the solenoid activated for 1 second
// Deactivate the solenoid
digitalWrite(solenoidPin, LOW);
delay(1000); // Wait for 1 second before next cycle
}
Troubleshooting and FAQs
Common Issues
- Solenoid Does Not Actuate: Check power supply and connections.
- Overheating: Ensure proper duty cycle and activation time.
- Weak Force: Verify that the voltage matches the solenoid's rating.
FAQs
Q: Can I operate the solenoid with a different voltage? A: Operating the solenoid outside its rated voltage can damage the component or affect performance.
Q: How can I reverse the motion of the solenoid? A: Reversing the polarity will not reverse the motion. Push-pull solenoids are designed to push or pull depending on the mechanical configuration, not the electrical polarity.
Q: What is the purpose of the flyback diode? A: The diode protects the driving circuit from voltage spikes generated when the solenoid is turned off.
