Hydraulics sealing when using a RF sensor in a pressure rod
HD / HL / HP
There are two ways to seal the flange contact surface (Fig. 36):
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 end cap groove.
2. A sealing by using an O-ring in the undercut.
For threaded flange (¾"-16 UNF-3A) »S«:
O-ring 16.4 × 2.2 mm (0.65 × 0.09 in.) (part no. 560 315)
For threaded flange (M18×1.5-6g) »M«:
O-ring 15.3 × 2.2 mm (0.60 × 0.09 in.) (part no. 401 133)
In this case, a screw hole based on ISO 6149-1 must be provided
(Fig. 37). See ISO 6149-1 for further information.
This is the way you mount the RF sensors:
Sensor design Mounting
RF-C • Insert the flexible sensor rod in a support
tube.
• Mount the sensor electronics housing by
means of 2 non-magnetic socket head
screws M4×59. Fastening torque: 2 Nm
(see Fig. 34)
Recommendation:
Seal the sensor via flange.
RF-C with pressure
rod HD / HL / HP
or HFP profile
(see “Frequently or-
dered accessories”)
Advantage: The flexible sensor rod is inser-
ted in a support tube.
• Mount the sensor electronics housing by
means of 2 non-magnetic socket head
screws M4×59.
Fastening torque: 2 Nm (see Fig. 34)
RF-M / RF-S • Insert the flexible sensor rod in a support
tube.
• Mount the sensor via flange.
Installation of RF with threaded flange »M«, »S« or RF with pressure
rod HD / HL / HP
Fix the sensor rod via threaded flange M18×1.5-6g or ¾"-16 UNF-3A.

Installation of a RF sensor with pressure rod HD / HL / HP
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 only 2 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
“4.8 Replacement of sensor” on page 37.
