This 5V electromagnet provides 5kg of holding force when energised with approximately 5V DC (4–6V working range). When the power is switched off, the magnet loses its magnetic field, making it suitable for small controllable locking, sorting, and pick-and-place applications.

Since it behaves as an inductive load, you should drive it through a motor or solenoid driver with flyback (kick-back) protection to avoid damaging your microcontroller.

Key Features

  • Holding Force – 5kg (11 lb)
  • Working Voltage – DC 4–6V (nominal 5V)
  • Model – P25/20
  • Instant On/Off – Magnetic only when powered

Ideal For

  • Small electromagnetic locks and latches
  • Lightweight pick-and-place mechanisms
  • Robotics and automation projects
  • Interactive installations and exhibits

Package Contents

  • 1× 5V Electromagnet (5kg holding force, P25/20)
Note: Holding force is not the same as pick-up weight. Divide by 5–10 for an approximate pick-up capacity (~0.5–1kg). Actual performance depends on the contact surface being flat and the object being ferromagnetic steel.
Other sizes available: 2.5kg, 3kg, 8kg, 10kg, 15kg, 20kg, 25kg, 30kg, and 35kg.
