1. Introduction
This manual provides essential information for the safe and effective use of the Heschen HS-1578B DC12V Solenoid Electromagnet. This device is a pull-push type, linear motion, open-frame solenoid with a plunger spring return mechanism. It is designed for various applications requiring controlled linear actuation.
2. Safety Information
WARNING: Read all safety instructions before installation and operation.
- Overheating Risk: Electromagnets generate heat when energized. They are not designed for continuous operation and require periodic switching on and off to prevent overheating and potential damage.
- Power Supply: Ensure the power supply matches the solenoid's rated voltage and current. Using a power supply with insufficient power may lead to malfunction or damage.
- Electrical Connections: All electrical connections should be made by qualified personnel, following local electrical codes and safety standards.
- Mounting: Securely mount the solenoid to a stable surface to prevent movement during operation.
- Moving Parts: Keep hands and other objects clear of the plunger during operation to avoid injury.
3. Product Features

5. Setup and Installation
- Mounting: Securely attach the solenoid to your application's frame or mounting surface using appropriate fasteners. Ensure the mounting allows for the full 20mm stroke of the plunger without obstruction.
- Electrical Connection: Connect the solenoid's wires to a DC12V power source capable of supplying 9.1A. Observe correct polarity if specified, though solenoids typically operate regardless of DC polarity for simple actuation.
- Plunger Alignment: Ensure the plunger is correctly aligned with the object it needs to push or pull. The solenoid operates by pulling or pushing the plunger when energized.
- Shim Removal (if applicable): The product may include a shim for protection or specific force requirements. If a force of 100N is required, the shim should be removed. Refer to the product image for shim location.

6. Operating Instructions
The Heschen HS-1578B operates as a push-pull type solenoid. When electrical current is applied, the plunger moves, performing work. When the current is removed, the spring returns the plunger to its initial position.
- Energizing: Apply DC12V power to the solenoid's wires. The plunger will retract or extend (depending on mounting and connection) to its energized position, applying the specified force.
- De-energizing: Remove the DC12V power. The internal spring will return the plunger to its initial, de-energized position.
- Duty Cycle: Adhere strictly to the ED%=30% duty cycle. This means the solenoid should only be energized for 30% of its total operating time within a cycle. For example, if a cycle is 10 seconds, it should be energized for a maximum of 3 seconds and de-energized for at least 7 seconds. Exceeding this duty cycle will lead to overheating and permanent damage.

7. Maintenance
The Heschen HS-1578B Solenoid Electromagnet is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:
- Cleanliness: Keep the solenoid free from dust, dirt, and debris, especially around the plunger mechanism, to ensure smooth operation.
- Connections: Periodically inspect electrical connections for tightness and signs of corrosion.
- Plunger Movement: Ensure the plunger moves freely without binding or excessive friction.
- Temperature: Monitor the operating temperature. If the solenoid consistently runs hotter than expected within its specified duty cycle, investigate the power supply or application.
8. Troubleshooting
If you encounter issues with your Heschen HS-1578B Solenoid Electromagnet, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Solenoid does not actuate when energized. | No power, incorrect voltage, insufficient current, loose wiring, damaged coil. | Check power supply (DC12V, 9.1A minimum). Verify all electrical connections are secure. Test the coil for continuity. |
| Solenoid actuates weakly or incompletely. | Insufficient current from power supply, mechanical obstruction, incorrect shim configuration. | Ensure power supply can deliver 9.1A. Check for any physical obstructions preventing full stroke. Verify shim removal if 100N force is required. |
| Solenoid overheats rapidly. | Exceeding duty cycle (ED%=30%), continuous energization, incorrect voltage. | Strictly adhere to the 30% duty cycle. Ensure the solenoid is not continuously energized. Verify input voltage is DC12V. |
| Plunger does not return to initial position. | Damaged return spring, mechanical obstruction, residual magnetism. | Inspect the return spring for damage. Check for any physical obstructions. Ensure the iron core is not sticking due to residual magnetism (rare for open-frame types but possible). |
