For non-contact sensor models air gap and alignment of sensor and
position magnet has to be observed. The linearity will degrade in case of
misalignment.
Adjacent magnetic fields or ferromagnetic materials can influence the
measurement results of the PRDS sensors of the POSIROT
®
product
family. Therefore the angle sensors should be mounted solely with
nonmagnetic / non magnetisable shims and screws.
The angle sensors PRDS2, PRDS3 and PRDS5, PRDS6, PRDS7
are equipped with an integrated magnetic shield which minimizes the
sensitivity against external magnetic fields.
Optional shield plates are available for the angle sensor PRDS27. They
can decrease the effect of residual magnetizing in case the sensor has to
be mounted on a ferromagnetic material (see page 9).
It is however not possible to exclude the effect of lateral external magnetic
fields.
Description
The angle sensors PRDS of the POSIROT
®
product family perform touch-
less or shaft based angle measurement. A position magnet rotates in front
of the sensing area of the sensor head. The angular position is converted
into a standardized incremental output. Resolutions up to 1024 pulses per
revolution are available.

•
Prevent the sensor shaft from binding.
•
For sensors with shaft use shaft couplings resp. torque arms (e.g.
flexible ones) to avoid misalignment errors (
see Accessoires „Cou-
plings“ p. 48
)
Mechanical information PRDS27
•
Mount the sensor on a flat surface.
•
Do not deform the sensor housing!
