This miniature push-pull solenoid features a captive armature with a return spring — when energised at ~5 V DC, the armature retracts, and when power is removed it springs back to its original position. The dual-action design lets you use it as either a push or pull mechanism, and the built-in mounting tabs make installation straightforward.
Key Features
- Push-Pull Operation – Captive armature works in both directions
- Return Spring – Automatically resets when de-energised
- 5 V DC Nominal – ~1 A inrush current when activated
- Compact – 20 mm body length
- Mounting Tabs – Built-in tabs for easy installation
Important: To drive a solenoid from an Arduino or other microcontroller, you will need a power transistor (e.g. TIP120 or logic-level MOSFET) and a flyback protection diode across the solenoid coil. The ~1 A inrush current is too high to power directly from USB — use an external 5 V supply rated for at least 1 A.
Ideal For
- Door locks and latch mechanisms
- Robotic actuators and dispensers
- Arduino and microcontroller automation projects
- Pinball machines and interactive exhibits
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- flyback protection
- A protection method used with coils such as relays, solenoids, and motors to absorb the voltage spike created when the coil is switched off. Adding a diode for flyback protection helps prevent damage to transistors, microcontrollers, or other control electronics.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
