DC 12V Mini Push-Pull Solenoid Electromagnet 4mm Stroke LY-033
DC 12V Mini Push-Pull Solenoid Electromagnet 4mm Stroke LY-033
DC 12V Mini Push-Pull Solenoid Electromagnet (Model LY-033)
The LY-033 Mini Solenoid Electromagnet is a compact, open-frame push-pull electromagnet designed for precise linear actuation in a wide variety of automation and electronics projects. Operating at DC 12V with a clean 4mm stroke, this small but capable solenoid is ideal for builders, engineers, and hobbyists who need reliable, repeatable mechanical motion in a tight footprint.
Key Features
- Compact Open-Frame Design: Measures just 20mm × 29mm × 16mm — easy to embed into enclosures, mechanisms, and custom builds.
- Push-Pull Action: Versatile bidirectional operation suits locking, triggering, and indexing applications.
- 4mm Stroke: Delivers precise, consistent linear movement every actuation cycle.
- Initial Force 0.5N (50g) / Keeping Force 5N: Strong holding force relative to the unit's small size.
- DC 12V / 0.5A Input: Compatible with standard 12V DC power supplies and microcontroller relay outputs.
- Intermittent Duty Cycle: Engineered for intermittent operation — recommended on-time of no more than 5 seconds per cycle for optimal longevity.

Important Usage Note
This solenoid is designed for intermittent duty only (e.g., 1 second ON / 1 second OFF). Continuous energization will cause the coil temperature to rise and may damage the unit. Always allow adequate cooling time between cycles. Operating in a well-ventilated environment further extends service life.

Frequently Asked Questions
Q: What is the maximum continuous on-time for the LY-033 solenoid electromagnet?
A: It is recommended to keep the continuous energized (on) time to no more than 5 seconds. The longer the interval between activations, the better — this allows the coil to cool down and significantly extends the working life of the solenoid.
Q: What voltage and current does the LY-033 mini solenoid require?
A: The LY-033 operates on DC 12V at 0.5A. It is compatible with standard 12V DC power adapters, regulated bench supplies, or relay-switched outputs from microcontrollers such as Arduino or Raspberry Pi.
Q: Can this push-pull solenoid be used as a miniature bolt lock?
A: Yes. The LY-033's 4mm stroke and 5N keeping force make it well-suited for lightweight bolt-locking and latching mechanisms, such as small cabinet locks, triggering devices, or automated release systems in custom builds.
Q: What does "open frame" mean for this solenoid?
A: "Open frame" means the solenoid coil and plunger assembly are not enclosed in a sealed housing. This makes the unit easy to mount flush inside equipment enclosures and allows for better heat dissipation, though it also means the internal components are exposed and should be protected from moisture and debris.
