NOTICE
Please observe the following information:
b
Ensure that the circlip and the corrugated spring washer are made from non-mag‐
netic material (non-ferritic steel).
b
Ensure that the position magnet and the circlip do not rub against the pressure
pipe.
b
Smalley circlip (
): does not contain any internal edges or eyes for the
pressure pipe.
b
Observe the operating pressures: see “Technical data”,
b
Consider bore hole depth in the piston and piston rod.
b
Axial holding force of the position magnet is determined by the spring constant of
the corrugated spring washer (approx. 15 N to 20 N) .
b
No direct contact of the ring surface of the position magnet to the piston head.
