4.1 Sensor installation
General
• Seat the flange contact surface completely on the cylinder
mounting surface.
• The cylinder manufacturer determines the pressure-
resistant gasket (copper gasket, O-ring, etc.).
• The position magnet should not grind on the sensor rod.
• The piston rod drilling (≥ Ø 13 mm / for GB-J and GB-K
sensors: ≥ Ø 16 mm) depends on the pressure and piston
speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.
GB-Series with pressure fit flange
Mount the sensor via the fitting flange through the bores
in the sensor electronics housing with 6 machine screws
M6×16 A2-70 (ISO 4762). Note the fastening torque of 6 Nm.
The hydraulic sealing requires the use of a supplied O-ring
15 × 2 mm (GB-J: 17 x 2 mm).
GB-Series with threaded flange
Mount the sensor via the threaded flange M18×1.5-6g or
¾"-16 UNF-3A. Note the fastening torque of 50 Nm.
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.
Typical use of magnets
Ring magnet
• Rotationally symmetrical magnetic field
U-magnet
• The magnet can be lifted off
• Height tolerances can be compensated

Non-magnetic mounting device and screws
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

• 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.
The maximum permissible air gap must not be exceeded.
