VEM SERIE
The attraction and holding of the magnetic pieces are obtained feeding
the winding inside the solenoid. When the power supply stops the
electromagnet looses the piece.
When working with loads security norms must be respected.
Protection rate: IP65
Insulation class: B (130ºC)
Standard voltage: 24 VDC
Standard duty cycle: ED100%
Other voltages,ED and sizes: Consult
Flying leads for every size.
Supply possibilities under demand:
.With campling screw from the VEM25
.With connector from the VEM65.
The connector (1) has 4 possibilities of direction (4x90º)
and it is possible to be incorporated to the same diodes
of rectification for alterning current connection (AC).
Flying leads: Ref: VEM (type)-V - ED%
Example: VEM 65-24Vdc- ED100%
Connector (C): Ref: VEM (type)/C-V-ED%
Example: VEM65/C-24Vdc ED100%
Connection:
see documentation that is enclosed with the material
Clamping screw (B): Ref: VEM(type)/B-V-ED%
Example: VEM50/B-24Vdc-ED100%
Important: the clamping screw does not
have to exceed measure D
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.

e (mm): Thickness of the piece to hold
The table 2 gives for each type of holding magnet, the values of the force of
maintenance (Fm) based on the air gap, measured in the following conditions:
-Direct current supply.
-Flat piece (3mm rugosity) in AºSt37, thickness as shown in the table 2 and dimensions
are similar or bigger than the attraction face.
-Room temperature 35ºC.
-Coil working on its regime temperature.
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.
.Earthing is recommended if the metallic parts are accessible.
.Technical explanation: see documents 1.4 & 1.5
.Under demand: any size, voltage, duty cycle etc can be manufactured
