2. Proper use
The magnetic grippers of the HM1000 series are based on the effect of a permanent magnet. This gripper may only be used to
handle workpieces made of ferromagnetic materials. Handling workpieces that generate their own active electromagnetic field or
themselves act as a permanent magnet may lead to malfunctions and therefore is regarded as improper use.
NOTE:
The magnetic grippers of the HM1000 series may only be used in their original state, with original accessories,
without any unauthorized changes and within the scope of their defined parameters for use.
Zimmer GmbH accepts no liability for any damage caused by improper use
3. Function
The magnetic grippers of the HM1000 series generate the gripping force, referred to here as the adhesive force, by means of a
permanent magnet.
A demagnetized contact plate provides for process-reliable depositing of the workpieces. The residual holding force is less than 1 N.
A spring holds the permanent magnet in the working position. A single-acting pneumatic cylinder moves the permanent magnet into the
detachment position only to deposit the workpiece. This means that only one pneumatic power supply line is needed for the gripper.

Information:
The adhesive forces depend on the surface quality and material thickness of the workpieces to be handled.
As a rule: "The rougher the surface, the lower the residual adhesive forces."
"The lower the material thickness, the lower the holding forces."
The holding force depends on the ferromagnetic properties of the workpieces being handled.
Assuming a holding force of 100% for technically pure iron, the following materials may be assumed to have:
St37:
0.94%
/ St34:
0.82%
/ St50:
0.75%
/ St70:
0.7%
/ 20MnCr5:
0.5%
/ Cast iron:
0.3%
Warning:
The magnetic gripper contains a permanent magnet. The magnetic field can pose a health hazard to persons with
electronic implants (such as a pacemaker).
►
Health hazard
► Avoid staying within the effective range of the magnetic field
Danger:
Unintended ignition sources can arise from the magnetic field. For this reason, use within potentially explosive
environments is not permitted.
►
Risk of fatal injury
