Need a small, powerful linear motion for a DIY project, model, or prototype? This is a micro tubular solenoid actuator, also called a push/pull-type linear electromagnet. When you apply DC voltage, the internal plunger moves in or out, creating a short, strong mechanical push or pull. The cool thing? It's available in a range of operating voltages: 3V, 5V, 9V, 12V, or 24V DC – perfect for matching with Arduino, Raspberry Pi, or other microcontroller projects. It has a compact tubular form factor with pin terminals for easy wiring. It's an unbranded/generic component, bulk packaged, and manufactured in China. Great for automating small locks, latches, valves, or creating moving parts in robots and gadgets. A must-have for electronics hobbyists, makers, and engineers working on automated systems. Just choose your voltage, wire it up with a driver circuit, and add linear motion to your creation!
