Detailed performance data for the switchable magnetic clamp TMC 300
Values shown for the performance of the TMC 300 are based on measurements made on material S235 JR,
comparable to AISI 1020 Cold Rolled Steel, for the maximum, vertical breakaway force at 0° deviation from the
load axis and additionally under a 90° inclined load. These values do not include any safety factor. The magnetic
clamp will detach itself abruptly when the load exceeds values given in table 2.

During each application, watch for any deformation of the work piece that might occur. If an air gap forms between
the magnetic surface and the work piece, the magnetic clamp will not reach the stated holding force and could
detach itself. Please check for any air gap developing at the edges of the TiN-coated magnetic surface if necessary
(e.g. with a sheet of paper; 80g/m
2
).
Immediately stop the operation if there is any excessive deformation of the work piece or if an
air gap occurs.
Never exceed the dimensions and/or the load-bearing capacity of the material thickness given
In table 2.
