4. Installation & mounting

4.1 Magnet installation

Typical use of magnets
For: GH & GT2 / GT3
• Rotationally symmetrical magnetic field
Ring magnet
For: GH, GT2 / GT3 & GP
• The magnet can be lifted off
• Height tolerances can be compensated
U-magnet
For: GH & GP
• The magnet can be lifted off
• Height tolerances can be compensated
Block magnet
For: GP
• The magnet is guided through the profile
• The distance between the magnet and the
Magnet slider
waveguide is strictly defined
• Easy coupling via the ball joint
Install the magnet using non-magnetic material for mounting
device, screws, spacers etc.. The magnet must not grind on
the sensor rod. Alignment errors are compensated via the
air gap.
• Max. permissible surface pressure: 40 N/mm
(only for ring magnets and U-magnets)
• Fastening torque for M4 screws: 1 Nm; use washers,
if necessary
• Minimum distance between position magnet and any
magnetic material has to be 15 mm.
• If no other option exists and magnetic material is used,
observe the specified dimensions
NOTICE
Mount the ring magnet and U-magnet concentrically.
Mount the block magnet centrically.
The maximum permissible air gap must not be exceeded.

Magnet mounting with magnetic material
A. If the position magnet aligns with the drilled piston rod
B. If the position magnet is set further into the drilled piston
rod, install another non-magnetic spacer above the magnet

Notice for sensors with stroke lengths ≥ 1 meter
Support horizontally installed sensors with a stroke length
from 1 meter mechanically at the rod end. Without the use of
a support, rod and position magnet may be damaged. A false
measurement is also possible. Longer rods require evenly
distributed mechanical support over the entire length. Use an
U-magnet for measurement.
