DC 12V/24V Push-Pull Solenoid Electromagnet 10mm Stroke
DC 12V/24V Push-Pull Solenoid Electromagnet 10mm Stroke
SARY LY-078 Open Frame Solenoid Electromagnet – DC 12V / 24V, 10mm Stroke
The SARY LY-078 Push-Pull Solenoid Electromagnet is an open-frame coil design engineered for continuous long-duration operation — a significant upgrade over conventional solenoids that can overheat or fail after just a few minutes of uninterrupted use. Whether you're building amusement equipment, vending machines, office automation systems, or industrial machinery, this compact and reliable solenoid delivers consistent performance you can count on.
Why Choose the LY-078 Solenoid?
- Continuous Duty Capable: Specially improved coil design allows extended operation (up to 24 hours recommended maximum) without coil damage.
- Dual Voltage Compatibility: Operates at DC 12V (0.3A) or DC 24V (0.18A) — flexible integration into a wide range of control systems.
- Push-Pull Action: Power-on retract / power-off extend operation with a 10mm telescopic stroke.
- Reliable Force Output: 80g initial actuation force and 5N holding power for precise, repeatable motion control.
- Compact & Lightweight: Measures just 37 × 20 × 26 mm and weighs only 105 grams — easy to mount in tight spaces.
- Thermal Stability: Temperature rises during operation then naturally stabilizes; a cooler operating environment further extends service life.

Important Usage Note
Like all solenoids, this electromagnet will generate some heat during operation. This is normal — the temperature rises and then stabilizes at a safe level. For best longevity, operate in a well-ventilated environment and avoid exceeding the 24-hour continuous run recommendation.

Frequently Asked Questions
Q: Can this solenoid electromagnet really run continuously without overheating?
A: Yes. The LY-078 features an improved coil design that allows it to operate continuously for extended periods — up to 24 hours is recommended. Unlike standard solenoids that may fail after just a few minutes of non-stop use, this unit is engineered for long-duty-cycle applications in vending machines, automation equipment, and more.
Q: What is the difference between the DC 12V and DC 24V versions?
A: Both versions deliver the same mechanical performance (10mm stroke, 80g initial force, 5N holding power). The DC 12V variant draws 0.3A, while the DC 24V variant draws 0.18A. Choose the voltage that matches your existing power supply or control circuit.
Q: What does "power-on retract / power-off extend" mean?
A: When electrical power is applied to the coil, the plunger retracts (pulls inward). When power is removed, an internal spring extends (pushes) the plunger back to its original position. This is standard "pull-type" solenoid behavior, ideal for latching, indexing, or trigger mechanisms.
Q: Is this solenoid suitable for outdoor or high-humidity environments?
A: The LY-078 is designed for general indoor use in equipment and machinery. If your application involves exposure to moisture, dust, or harsh conditions, additional enclosure or sealing is recommended to protect the coil and ensure reliable long-term performance.
