4.2 Magnet installation
Typical use of magnets
Ring magnet
For: EH
• Rotationally symmetrical magnetic field
U-magnet
For: EH & EP
• Height tolerances can be compensated
Block magnet
For: EP, EL, EP2 & EH
• The magnet can be lifted off
• Height tolerances can be compensated
Magnet slider
For: EP & EL
• The magnet is guided through the
profile
• The distance between the magnet and
the waveguide is strictly defined
• Easy coupling via the ball joint

Non-magnetic mounting device and screws
Mounting ring magnets, U-magnets & block magnets
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.
• Permissible surface pressure: Max. 40 N/mm
2
(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 (0.6 in.).
• If no other option exists and magnetic material is used,
observe the specified dimensions.
NOTICE
Mount ring magnets and U-magnets concentrically.
Mount block magnets centrically over the sensor rod or
the sensor profile.
Do not exceed the maximum acceptable gap.
Take care to mount the sensor in an axially parallel
position to avoid damage of the carriage, magnet and
sensor rod.
Controlling design dimensions are in millimeters and
measurements in ( ) are in inches

Magnet mounting with magnetic material
When using magnetic material the dimensions must be
observed.
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
