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.

IMPORTANT: THE CLAMPING SCREW DOES NOT TO EXCEED MEASURE D
The table gives for each type of holding magnet, the values of the minimum pulse time and resting time measured in the following conditions:
- With a weight of 5% of the maximum magnetic force made by each model.
- Coil working on its regime temperature.
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 AºSt37 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.
Under demand an internal protection can be added to the coil to protect it of the overheating, generated by the no respecting of the times given by the duty cycles, this overheating can demagnetize the internal magnet or destroy the coil cahnging the proper working of holding magnet.
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.
