POSIROT®– PRDS
Safety instructions
If total failure or malfunction of the sensor can cause danger or
injury to the operator or damage to the machinery or equipment
it is recommended that additional safety measures should be
incorporated into the system.
Any alteration, reconstruction or extension of the sensor is not
allowed.
Sensor must be operated only within values specied in the
datasheet.
Connection to power supply must be performed in accordance
with safety instructions for electrical facilities and performed
only by trained staff.
Do not connect / disconnect the sensor under tension.
Disregard of this advice can lead to malfunctions, damage to
property or personal injury and releases the manufacturer from
product liability.

not avoided, could result in serious injury or property
damage.
WARNING, Risk of Personal Injury or Death:
Indicates a situation that can result in serious personal
injury or death if not properly avoided.
DANGER
WARNING, Risk of Personal Injury or Death:
Indicates a situation that can result in moderate
personal injury or death if not properly avoided.
WARNING
WARNING, Risk of Personal Injury:
Indicates a situation that can result in minor personal
injury if not properly avoided.
CAUTION
WARNING, Risk of Property Damage:
Indicates a situation that can result in minor to major
property damage if not properly avoided.

Maintenance and
service
• In order to avoid risk of injury and improper handling the
customer is not allowed to repair the sensor. No warranty or
liability will be granted for opened sensors.
• Damaged sensors must be shut down immediately and sent
to the factory for repair.
Proper maintenance comprises the visual examination of parts (e.g.
integrity of housing, connectors and cables). Maintenance intervals
dependonthespecicapplicationandshouldbedenedbytheuser
in dependance of operating conditions.
The following maintenance steps are recommended:
Maintenance-
interval
Deinstallation Disconnectelectricalconnections.Loosenxingscrews.
Disposal Disposal according to applicable government regulations.
The angle sensor was intended for angular position measurement, when
properly mounted and used in the specied ambient atmospheric and
technical conditions for which the sensor is designated.
The unintended use is when the sensor is used outside its specied
technical and ambient atmospheric conditions or when incorrectly
mounted.

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 elds or ferromagnetic materials can inuence 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
sensitivityagainstexternalmagneticelds.
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
elds.
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.

Electrical installation
Observe different color code for pre-assembled accessory cables - refer to
accessories pages.
The protection class of sensors with connector output is valid only if the
electrical plug is connected!
Do not twist the M12 connector insert.
Cable outputs must be installed in such a way that no moisture can get into
the cable. Crossing the dew point must be avoided.
Do not strain the connection cable.
A separate cord grip is recommended.
For wiring of connector or cable outlet as well as supply voltage and current
consumption see from page 16.
