Notice for metric threaded flanges
For additional information about optional accessories see:
• HFP profile (document part number: 551442)
• Pressure rod HD / HL / HP (document part number: 551770)
Note the following points when using a RF-M / -S sensor
respectively pressure rod HD / HL / HP:
• 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 for RF sensors with pressure rod (outer
diameter 12.7 mm (0.5 in.)) is ≥ 16 mm (≥ 0.63 in.). The borehole
depends on the pressure and piston speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.
4.7 Magnet installation
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 (Fig. 39 / Fig. 40).
Typical use of magnets
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.) (Fig. 41).
• If no other option exists and magnetic material is used, observe the
specified dimensions (Fig. 41).

through the profile
• The distance between the
magnet and the waveguide
is strictly defined
• Easy coupling via the
ball joint
