How to choose a suitable suction cup electromagnet ?

Suction cup electromagnet, also known as small round electromagnet, it is the most popular small device of electromagnetism. With  the rapidly development of technology, the types and uses of electromagnets are also increasing.  The following description and classification of suction cup electromagnets hope to help you quickly make the right choose the right suction cup electromagnet you need.

Part 1  How many Types of suction cup electromagnets ?

1  From the appearance:smallround tube suction cup electromagnet and square suction cup electromagnet;

The production cost of small round tube electromagnet is lower than the square suction cup electromagnet, and it is easy to install, but the suction area of square suction cup electromagnet is larger than the small round one.

Part 2. how to tel the different From the function: ordinary suction cup electromagnet and self-holding suction cup electromagnet;

Ordinary suction cup electromagnet: magnetism on when powered on, demagnetization when powered off;

Self-holding suction cup electromagnet: built-in a permanent magnet, magnetism when not powered on, magnetism disappears when powered on.

Part 3, what is the Characteristics of suction cup electromagnets:

The suction cup electromagnets are roughly classified from the function and appearance above. When purchasing suction cup electromagnets, we also need to know some characteristics of suction cup electromagnets.

1. Power supply: only DC power can be supplied, batteries, DC power, etc. can be used
2. Stroke: The suction cup electromagnet and permanent magnet are not powered at most, and the suction cup electromagnet stroke is almost 0. Only when the object being sucked is in contact with the electromagnet can the magnetism be maximized.
3. Suctioned object: It must be magnetically conductive, and the area being sucked must be larger than the suction surface of the electromagnet and it must be a flat surface; the thickness of the object being sucked cannot be too thin, generally more than 2mm is the best.

Power-on rate and temperature rise: Under normal circumstances, the power-on rate set by the manufacturer is 100%, and the normal temperature rise is below 65℃.

Part 4 ;  Our solution for small round electromagnets

We can offer the Diameter of small electromagnet from 12 mm to 150 mm. Height option of small round electromagnet range from 18 mm to 73mm. As for the holding force of small round electromagnets. We can control the ranges from 4lbs to 1000lbs. If you have a special request or need the rectangle one or the square electromagnet, we can make the one as per your specification accordingly.

For best application, we suggest to use the round flat-faced electromagnets on surfaces that are smooth, flat, and dry. A round flat-faced magnet is able to achieve its maximum holding force when the entire face of the magnet is permitted to come into direct contact with the product being handled. the Round flat-faced electromagnets are designed with a center magnetic pole, and use their outer casing as an opposite pole. This design is able to concentrate magnetic force at the center of the magnet, and the result is superior good.

Every round small flat-faced electromagnet from dr. Solenoid is durable and long lifespan. Round flat-faced electromagnets are able to facilitate automation of tasks within your facility and provide an alternative to mechanical holding devices.  It is a simple, safe, and efficient. Device. Small round electromagnets do not have any moving parts, such as springs or valves, that are at risk of running out. What is more, the small round electromagnets do not produce any waste during application. Low-maintenance electromagnets facilitate easy transfer of large and heavy ferrous materials. All electromagnets from Dr. Solenoid are 100% duty cycle.

Summery :

There are two kind of popular holding electromagnet on the market.  The small round one or the square one.  By function, one is power on and the magnet on. No , power , not magnet.  The other one is Self-holding suction cup electromagnet with built in permanent magnet. Without power, the magnet is always on, when power on, the magnet gone.
