JF-1039B 2A linear push-pull solenoid electromagnet

JF-1039B 2A linear push-pull solenoid electromagnet
Key Specifications

• Voltage: Typically 12V DC, but also available in 6V or 24V.
• Current: Rated up to 2A (or 400mA depending on the exact coil resistance).
• Force: 25N (Newtons). A Newton is the force needed to accelerate 1kg of mass at 1m/s². Think of 25N as roughly lifting or pushing a 2.5kg (5.5lb) weight.
• Stroke (Travel Distance): up to 10mm. 

How It WorksA solenoid acts like a remote-controlled magnet. Think of it as a gate that opens and closes using electricity. When you apply power (e.g., 12V), an internal copper wire coil creates a magnetic field. This magnetic field pulls or pushes the metal plunger forward. An internal spring forces the plunger back to its resting position once the power turns off. Common ApplicationsBecause it delivers quick, strong linear movement, you will find it used in:

• Electric Door Locks
• Vending Machines (to drop snacks or dispense change)
• Automated Sorters
• DIY Robotics and Arcade Games 

Important Safety and Usage Tips

• Heat: These electromagnets pull a lot of power and get very hot very fast.
• Duty Cycle: To prevent the coil from melting, do not leave it turned on continuously. The best operating time is usually less than 2 to 30 seconds at a time.
