Installation and connection (continued)
Installation recommendation for hydraulic cylinders
If installing horizontally in a hydraulic cylinder (measuring
lengths > 500 mm), we recommend affixing a slide element
to protect the rod end from wear.
Dimensioning of the detailed solutions is the
responsibility of the cylinder manufacturer.
The slide element material must be suitable for the
appropriate load case, medium used, and application
temperatures. E.g. Torlon, Teflon or bronze are all possible
materials.

The slide element can be screwed on or bonded.
► Secure the screws so they cannot be loosened or lost.
► Select a suitable adhesive.

There must be a gap between the slide element and piston
bore that is sufficiently large for the hydraulic oil to flow
through.
Options for fixing the magnet:
– Screws
– Threaded ring
– Press fitting
– Notches (center punching)

Rod
If installed in a hydraulic cylinder, the magnet
should not make contact with the rod.
The hole in the spacer ring must ensure optimum guidance
of the rod by the slide element.
