Safety

2.1

Intended use

The position transmitter SDAS-MHS is intended for monitoring the piston stroke.
Only use the position transmitter for suitable drives from Festo
è www.festo.com/catalogue. Avoid positioning magnetic objects in close prox-
imity to the position transmitter.

The position transmitter detects the magnetic field of the piston magnet and con-
tinuously senses the piston movement in the sensing range. The position trans-
mitter can be operated in one of the following operating modes:
– Cylinder switch with 2 programmable switching points (standard operation) .
– Position transmitter with IO-Link communication .
In the case of active IO-Link communication (IO-Link master required), the SDAS-
MHS switches automatically into the position transmitter operating mode.
5.1
In the cylinder switch operating mode, 2 switching points can be programmed
within the sensing range.
– Operation using capacitive operating key
– Switching logic: normally open (NO)
– Output signal 24 V DC (PNP or NPN)
– Marking on the housing indicates the centre of the sensing range.

Fig. 2 Application example: Cylinder switch operating mode
5.2
In the position transmitter operating mode, programmed switching signals and
the continuous position values (digitally coded analogue values) are transferred.
– Programming via IO-Link
– Device description file IODD è www.festo.com/sp.
– Capacitive operating key is deactivated.
– Cylinder switches or window comparators or hysteresis comparators can be
programmed individually on 4 switching channels.
– The continuous position values are always transferred in parallel with and
independently of the position value output of the switching channels.
– Each channel can be set to be normally closed (NC) or normally open (NO).
– Data transmission is serially and digitally coded in the IO-Link protocol.
– Process data: 12 bit for position data and 4 bit for switching channels
– Unshielded standard cables of up to 20 m in length can be used.
– Parameters and functions in accordance with Smart Sensor profile
– Support for the optional functions "Block parameterisation" and "Data
storage"
