2 Safety
2.1 General safety information
Only use the product in its original condition without unauthorised modifications.
Avoid having magnetic bodies near the position sensor. These could influence
the magnetic field and thereby the behaviour of the sensor.
This product can generate high frequency interference, which may make it ne
cessary to implement interference suppression measures in residential areas.
Installation and commissioning only by qualified personnel and in accordance
with the operating instructions.
2.2 Intended use
The position transmitter SDAT-MHS is intended for contactless detection of
the piston position of magnetic-sensing drives and grippers. It is appropriate
for use with with Festo drives with T-slot (profile slot 8) as well as round cylinders
and tie-rod cylinders with mounting kits.
Use the SDAT-MHS only for the suitable drives and grippers from Festo

Only for connection to an NEC Class 2 supply.
Raccorder Uniquement a un circuit de Classe 2.
This device is intended to be used with a Class 2 power source or Class 2 trans
former in accordance with UL1310 or UL1585.
As an alternative, an LV/C (Limited Voltage/Current) power source with one of
the following properties can be used:
– This device shall be used with a suitable isolating source such that the
maximum open circuit voltage potential available to the product is not more
than 30 V DC and the current is limited to a value not exceeding 8 amperes
measured after 1 minute of operation.
– This device shall be used with a suitable isolating source in conjunction with
a fuse in accordance with UL248. The fuse shall be rated max. 3.3 A and
be installed in the 30 V DC power supply to the device in order to limit
the available current.
Note that, when more than one power supply or isolating device is used,
connection in parallel is not permitted.

Warning
Risk of injury due to electric shock.
Injury caused by electric shock, damage to machine and to system
For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
Observe IEC 60204-1/EN 60204-1.
Switched-mode power supplies are permitted, provided that they ensure
reliable separation in accordance with EN 60950/VDE 0805.
