      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.

      Under demand

      • With campling screw from the VM25, with connector from the VM65.
      • The connector (1) has 4 possibilities of direction (4×90º) and it is possible to be incorporated to the same diodes of rectification for alterning current connection (AC).

      IMPORTANT: THE CLAMPING SCREW DOES NOT TO HAVE TO EXCEED THE MEASURE D

      The data shown in the chart are the Magnetic Force (Fm) values depending on the air gap, measured in the following conditions:

      • Direct current supply
      • Flat piece (3 µm rugosity) in AºSt37 and thickness as shown.
      • Room temperature 35ºC.
      • Coil working on its regime temperature when operating.

      At different conditions the magnetic force (Fm) may decrease.

      The dimension of the pieces used in the test are similar or bigger than the attraction face of the different holding electromagnets. The value of the magnetic remanence after the power supply stops is 5% of the holding force.

      When lifting or handling heavy loads a minimum security margin of 3 must be respected, the weight of the load cannot exceed 33% of the magnetic force.
