Magnetic Door Holder

Magnetic Door Holder
  • ApplicationMagnetic door holder is widely used in disinfection cabinet, cabinet, refrigerator freezer and chest, etc to become the switch of cupboard door.

Detailed

Product Introduction:

 Magnetic door holder is a holding structure, which is made of molding plastic parts and rare earth permanent magnet. The plastic parts play an important way in fixing magnet, which adopts high quality and non-pollution plastic parts. Magnet is installed on the plastic parts through the function of magnetic holding to arrive the switch of cupboard door.

Technical Feature:

1.      Adopting rare earth permanent magnet, strong magnet, strength holding.

2.      Plastic parts adopt non-pollution plastic, smooth and beautiful surface.

3.      Low rate of magnetic demagnetization.

4.      Reasonable structure design, low failure rate.

Application:

(1)   Transportation: car, electrombile,  as picture.

(2)   Energy: dynamo, motor,         as picture.

(3)   Electronic product: mobile phone, computer, loudspeaker, as picture.

(4)   Instrument and meter:          as picture.

(5)   Magnetic separator:            as picture.
