Detailed Performance Data - ALFRA TMC 600 Mode D'emploi

DETAILED PERFORMANCE DATA FOR THE SWITCHABLE
MAGNETIC CLAMP TMC 600
Values shown for the performance of the TMC 600 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/m2).
