3 TECHNICAL SPECIFICATIONS
If the workpiece is significantly thinner than the pole spacing, the workpiece does not fully absorb the magnetic
field. This reduces the holding force. The best holding forces are achieved if all force lines run within the workpiece.
A guide value is that the holding force is not reduced if the workpiece thickness is > 40 % of the true pole pitch.
For thicker and blank workpieces, larger pole spacings can achieve greater penetration of the magnetic field and
therefore a greater holding force for these parts.
The minimum workpiece thicknesses must be observed (see section 3 “Technical specifications”).
