Product Description

Mini-Electro Magnets are the category of Magnets which get energized when electricity is applied to them according to the rating. 

They can be used for various applications such as:

  • Machine tools
  • Door locking / holding
  • Actuators
  • Feeder mechanism, Short stroke / high force operation
  • Automation e.g. Textile machinery, Packaging machinery, Office machinery
  • Grill locking
  • Transformers
  • Remote hold / release

Armature Plates

PML Armature Plate

The armature plates are quality ferromagnetic plates with fixing holes that are sized to suit both the energise to hold electromagnet and the energise to release electro permanent magnet.

They can be used as keeper plates in use to get the best clamping performance from the electromagnets and electro-permanent magnets and are often used when either no ferromagnetic material exists for the electromagnets to clamp onto or where the existing ferromagnetic surface is not ideal for best clamping (e.g. thin sheet, rusty steel, curved surfaces).

Our armature plates allow our electromagnets to perform at their best - optimum holding forces by combining high magnetic permeability, low remanence, minimised air gap and optimum magnetic pathways.

An electromagnet or electro-permanent magnet always needs a ferromagnetic surface to clamp onto – the ferromagnetic surface required is generally a mild steel or ferromagnetic stainless steel. The quality of the ferromagnetic material can affect the performance of the electromagnet or electro-permanent magnet. Thinner materials tend to struggle to carry the magnetism, magnetically saturating and failing to achieve the maximum possible holding forces of the magnets. Corroded materials and materials with poor magnetic permeability also result in reduced performance form the magnets. Surfaces that are not smooth (curved, rippled, indented) and surfaces that have coatings to create effective air gaps also cause reductions in the pull forces possible.

Each armature plate has a counterbore hole to allow a simple fixing means. The counterbore holes are designed to fit M3 up to M8 counterbore screws (depending on the size of armature plate).

FAQ for Mini electromagnet:

Q.  Can we use electromagnet for pick & place application?
See the video to get an answer:

Q.  Can electromagnet attract the metal parts from distance?
See the video to get an answer:

Q.  How to see flux density on the surface of an electromagnet?
See the video to get the answer:

Q.  How electromagnet is not suitable for sensor applications?
See the video to get the answer:

1. Can this magnet be used to sense the field at a different distance?
No. These magnets cannot be used to sense fields at distances. These magnets are essentially used for pick and place applications.

2. Is it possible to use this magnet to attract a body from certain distances?
Ans. No. This magnet cannot be used to attract an ms body from a certain distance, it may be possible to some extent if the bodies are either small in size or flat and long.

3. Can two electromagnets be used to oppose each other?
Ans. No two electromagnets cannot be used to oppose each other at a certain distance.

4. Can we generate an oscillating field from this magnet?
Ans. We can not generate an oscillating field from this electromagnet, it may be possible by passing DC current & AC current of some voltage.

5. Can we put this magnet in continuously on position?
Ans. Yes. These magnets can be put continuously in position. However, their life can get reduced due to internal heating. We will rather advise you to use electro-permanent magnets for such applications, power consumption would also be high.
6. Can we use an adapter of 24V with higher current capacity?
Ans. Yes, We can use an adapter of 24V with a higher current rating.

7. How to connect the electromagnet?
Ans. There is a separate video to connect the electromagnet. Please see it on our website

8. What is the field it can generate at different distances?
Ans. We do not have data on this field v/s distance. These magnets are designed for close circuit applications and hence the field intensities are very low at a distance of 5mm from the magnet, we can generate this field but it may not be enough to pull but maybe not enough to attract sensors.

9. Can we have a customized size magnet to suit our requirement of pull?
Ans. Mainly no. We have a standard range of electromagnets, it also depends upon MOQ i.e. minimum order quantity & development cost.

10. What is the maximum surface temperature of the magnet if it is put on for a few hours?
Ans. The maximum surface temperature could reach approx 70° C if the magnet is put 'ON' for a few hours.

11. Can we send this magnet for repair?
Ans. No. You can not send this for repair as the repair is not possible.

12. Will the winding burn of if it is continuously put on or someone forgets to switch it off?
Ans. The winding should not burn off even if it is put on for a certain number of hours.

13. Will it lift the designed load?
Ans. The magnet is supposed to lift designed load under certain ideal conditions like the thickness of job, job finish, job material, etc. A fully ground block of ms material of designed specification can be lifted, using this electromagnet.

14. Can we have a different mounting arrangement?
Ans. No. We do not offer customized mounting arrangements other than those specified in the catalog. It also depends upon the MOQ i.e. material order quantity and development cost.

15. Will the magnet surface corrode over a period of time?
Ans. The magnet body is made up of ms and has nickel plating. The magnet surface may corrode if the plating goes off. In such a case you may apply paint to prevent further corrosion.
