Installation of RH5 with threaded flange
Fix the sensor rod via threaded flange M18×1.5-6g, M22×1.5-6g or
¾"-16 UNF-3A.
Fig. 8: Mounting example of threaded flange
Installation in a fluid cylinder
The rod-style version has been developed for direct stroke
measurement in a fluid cylinder. Mount the sensor via threaded flange
or a hex nut.
• Mounted on the face of the piston, the position magnet travels
over the rod without touching it and indicates the exact position
through the rod wall – independent of the hydraulic fluid.
• The pressure resistant sensor rod is installed into a bore in the
piston rod.
• The base unit is mounted by means of three screws. It is the only
part that needs to be replaced if servicing is required, i.e. the
hydraulic circuit remains closed. For more information see chapter
"4.6 Replacement of sensor" on page 16.
In the event of servicing, the sensor rod
with flange remains in the cylinder

Hydraulics sealing
There are two ways to seal the flange contact surface (Fig. 10):
1. A sealing by using an O-ring (e.g. 22.4 × 2.65 mm (0.88 × 0.1 in.),
25.07 × 2.62 mm (0.99 × 0.1 in.)) in a cylinder bottom groove.
2. A sealing by using an O-ring in the undercut.
For threaded flange (¾"-16 UNF-3A):
O-ring 16.4 × 2.2 mm (0.65 × 0.09 in.) (part no. 560 315)
For threaded flange (M18×1.5-6g):
O-ring 15.3 × 2.2 mm (0.60 × 0.09 in.) (part no. 401 133)
For threaded flange (M22×1.5-6g):
O-ring 19.2 × 2.2 mm (0.76 × 0.09 in.) (part no. 561 337)
Fastening torque
RH5-M/S: 50 Nm
RH5-T: 55 Nm
RH5-J: 125 Nm
Position magnet
In the case of threaded flange M18×1.5-6g or M22×1.5-6g, provide
a screw hole based on ISO 6149-1 (Fig. 11). See ISO 6149-1 for further
information.
Fig. 10: Possibilities of sealing
• Note the fastening torque:
RH5-M/S: 50 Nm
RH5-T: 55 Nm
RH5-J: 125 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
(RH5-M/S/T-A/M/V with rod Ø 10 mm: ≥ Ø 13 mm (≥ Ø 0.51 in.);
RH5-M/S/T-B with rod Ø 10 mm:
RH5-J-A/V with rod Ø 12.7 mm:
depends on the pressure and piston speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.
