Automatic Mini Electro Permanent Lifting Magnet EPB-A660

Auto ON/OFF Mini electro permanent lifting magnets EPB-A660


Product Description

No need to rotate a lever or press a button during each lift operation. When the magnet lands on a steel plate each time, its magnetic status alternates, thus its lifting power is produced or disappeared. Operators only need to press the "ON/OFF" button at the beginning and end of lifting job. If required, magnetization can also be switched on or off by pressing the button of “MAG/DEMAG” at its front panel.


  • Automatic lifting and releasing your load
  • Safety Factor 3:1
  • Powerful yet extremely small and light
  • Operate in areas with limited space access
  • A collision barrier protecting it from impact
  • A display showing battery level
  • Automatically stop working after the battery level is too low
  • Green light shows the magnet has lifting power
  • Red light shows battery level is too low and the magnet stops working
  • Li-Po battery provides 300 cycles of lifting and releasing a load
  • Complying with ASME B30.20.

Product Specifications

  • Working Temperature = 23-113°F
  • Net Weight = 26 lbs
  • Dimension without collision barrier = 6" x 6" x 8"
  • Dimension with collision barrier = 7" x 7” x 8”

Operation (Note: Each time when the magnet lands on floor, the crane sling must be fully relaxed.)

Operator’s Action Magnet Function Battery Level Display Green Light of “MAG” “POWER” Red Light (Low Battery)
If the magnet is unmagnetized and not powered on, place it at a load and press ON/OFF button. Magnetized and thus attract the load Indicating battery level Green Off
If the magnet is unmagnetized and powered on, just place it at a load.
Lift the magnet with the load attracted and move them to destination. Stay Magnetized and its holding force, even in case of battery failure. Indicating battery level Green Off
Lower them down slowly and place them on the ground. Demagnetized and thus the holding force is cleared. Indicating battery level Off Off
Lift the magnet alone. Stay Demagnetized and no holding force. Indicating battery level Off Off
Repeat and Continue Lifting
When the Battery is too low for full magnetization. The magnet stops working, but still keeps the latest status, with or without holding force. Off Same as its latest status, Green or Off. Red
If both Green light and Red light are on, it means that the magnet is still attracting the load but not able to release it. In order to release the load from the magnet, lower the magnet to ground, press the ON/OFF button twice, then IMMEDIATELY press the MAG/DEMAG button. Magnetized and then demagnetized, so the holding force gets cleared. On then Off Green then Off Off then Red
Upon completion of task, always remember to have the magnet unmagnetized and not powered.
