Description
The attraction and holding of the magnetic pieces are made by permanent magnets mounted in the solenoid. With these kind of products, we avoid the risk of load falling due to sudden power supply failure. The power supply on the coil allows to loose the load, when this power supply stops, the product recovers its initial force. When working with hanged loads norms must be respected.
Supply possibilities
Connector DIN43650 with stuffing box for every size
Under demand: any size, volatge, duty cycle etc can be manufactured
Other supply possibilities can be made under demand.

For these holding electromagnet correct working the minimum pulse and resting time must be respected:
- Minimum pulse time: 300ms
- Minimum resting time: 5000ms
The values of the minimum pulse time and resting time measured in the following conditions:
- Coil working on its regime temperature.
- Piece weight: 2 kilos (it is not recommended to use these holding electromagnet for lower weights)
The data shown in the chart are the Magnetic Force (Fm) values depending on the air gap, measured in the following conditions:
- No power supply.
- Flat piece (3 µm rugosity) in AºSt 37 and thickness as shown.
- Room temperature 35ºC
The dimensions of the pieces used in the test are similar or bigger than the attraction face of the different holding electromagnets. At different conditions the magnetic force (Fm) may decrease. The value of the magnetic remanence after the power supply stops is 5% of the holding force.
When lifting or handling heavy loads a minimun security margin of 3 must be respected, the weight of the load cannot exceed 33% of the magnetic force.
