4.5 Magnet installation
Mounting the ring magnet
Install the magnet using non-magnetizable material for mounting
device, screws, spacers etc.
• Max. permissible surface pressure: 40 N/mm
2
• Max. fastening torque for M4 screws: 1 Nm; use washers,
if necessary
• Minimum distance between position magnet and any magnetic
material have to be 15 mm (0.6 in.).
If no other option exists and magnetic material is used, observe the
specified dimensions (Fig. 11)

Mounting the U-magnet
Using a non-magnetizable mounting device is mandatory. The magnet
must not grind on the sensor rod. Alignment errors are compensated
via the air gap.

• Max. fastening torque for M4 screws: 1 Nm; use washer,
if necessary
Large stroke lengths from 1 meter (39 in.)
Horizontally installed sensors should be supported mechanically
at the rod end. Longer rods require evenly distributed mechanical
support over the entire length. In this case (Fig. 13) the sensor rod
can be supported by fixing clips and an U-magnet can be used for
measurement.
NOTICE
A maximum permissible air gap of 3 mm (0.12 in.) must not be
exceeded.
