The P20/15 DC12V Electric Sucker Electromagnet 3KG is a compact circular electric lifting magnet designed to generate magnetic attraction when powered by a 12V DC supply. BDTronics offers this small electromagnetic sucker for robotics, automation, magnetic fixtures, locking mechanisms, DIY projects, and applications requiring electrically controlled magnetic holding or lifting.

The P20/15 uses an electromagnetic coil and iron core to produce magnetic force when energized. When the 12V power supply is switched off, the magnetic force is released, making it suitable for automated mechanisms that require controlled magnetic ON/OFF operation. Its compact 20mm × 15mm size is useful for small mechanisms where installation space is limited.

Working Principle:

An electromagnet generates a magnetic field by passing electrical current through a coil wound around an iron core. When 12V DC power is applied to the P20/15 coil, the resulting magnetic field is concentrated through the iron core and creates an attractive force at the flat contact surface.

When the power is removed, the magnetic field decreases and the attached ferromagnetic object can be released. This simple ON/OFF operation makes the P20/15 suitable for automated equipment, robotic mechanisms, electronic locks, magnetic clamps, and DIY projects.

For electronic control, the electromagnet can be switched using a suitable MOSFET, transistor, relay, PLC output, or other DC switching device. Because the coil is an inductive load, appropriate flyback protection should be provided when connecting it to semiconductor switching circuits.

Applications:

• Small robotics projects

• Robot grippers and end-effect mechanisms

• Industrial automation

• Pick-and-place mechanisms

• Small electromagnetic clamps

• Magnetic holding fixtures

• Automated locking mechanisms

• Metal part positioning

• Sorting mechanisms

• CNC and machinery mechanisms

• Arduino and microcontroller projects

• PLC-controlled mechanisms

• DIY automation projects

• Educational electronics projects

• Electromagnetic prototypes and experiments

Installation and Usage Guidelines:

The maximum magnetic force is achieved when the electromagnet makes close, direct contact with a suitable ferromagnetic surface.

1. Supply the electromagnet with the specified 12V DC voltage.

2. Use a suitable switching device when controlling the magnet from a microcontroller, PLC, or automation controller.

3. The target should be made from a material with good magnetic permeability.

4. Keep both magnetic surfaces clean and as flat as possible.

5. Minimize the air gap between the magnet and target.

6. Paint, dirt, plastic, uneven surfaces, and other non-magnetic materials can significantly reduce magnetic force.

7. Actual lifting force depends on target material, thickness, contact area, surface condition, and alignment.

8. The specified 3KG lifting capacity should not be considered guaranteed for every target or installation.

9. The coil can generate heat during continuous operation. Allow suitable thermal management for applications requiring long ON periods.

10. For lifting applications, use an appropriate safety factor and secure the load properly.

Important Notes:

The 3KG rating represents the specified maximum lifting capacity under suitable magnetic conditions. Actual performance can be considerably lower if the target is thin, rough, painted, curved, too small, or separated from the magnet by an air gap.

For reliable operation, ensure the magnet's contact surface is properly aligned with a sufficiently large and thick ferromagnetic target. Avoid using the maximum rated lifting force as the working load for safety-critical or overhead lifting applications.
