Operation Manual
Fig. 12:
Notice for threaded flange M18×1.5-6g based on DIN ISO 6149-1
•
Note the fastening torque of 50 Nm.
•
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 (≥ Ø 0.52 in.)) depends on the
pressure and piston speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.

Typical use of magnets
Magnet
Benefits
Ring magnets
•
Rotationally symmetrical magnetic field
U-magnets
• Height tolerances can be compensated
Mounting ring magnets and U-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
•
Fastening torque for M4 screws: 1 Nm; use washer, if necessary
• Minimum distance between position magnet and any magnetic
material has to be 15 mm (0.6 in.) (Fig. 15).
• If no other option exists and magnetic material is used, observe the
specified dimensions (Fig. 15).

Typical use of ring magnets and U-magnets
NOTICE
Mount ring magnets and U-magnets concentrically.
Do not exceed the maximum acceptable gap.
