Choosing The Correct Magnet - 493K K-METRON User Instructions

5 CHOOSING THE CORRECT MAGNET

The unit comes with three different types of magnets, a cube, a 10mm sphere, and a 19mm
sphere. The desired range of measurement will be the major factor which will determine
whether to use the cube or spherical magnet. The 10mm x 10mm x 10mm cube magnet is
best for thick-walled parts
supplied to help retrieve the magnet should it become de-coupled from the sensor head.
The 10mm spherical magnet is best for thinner parts when tight radii are to be measured.
The measurement specifications for each of the magnets are shown in the Table below.
