Linearity error The linearity error describes the maximum deviation of the output
signal fr
om an ideal straight line. It is measured in millimeters.
MPS-G with 2/3 digital switching points and IO-Link (up to 16
switching points): The linearity error is typically 0.5 mm and
depends on the measuring range and the drive on which the sen‐
sor is mounted.
Measuring range The measuring range can be anywhere inside the detection range.
The me
asuring range must always be completely inside the detec‐
tion range.
Offset The offset is added to the position identified by the sensor. Nega‐
tive position values can be output depending on the positioning of
the sensor on the drive. If you do not want this, an offset value can
be defined around which all position values are added.
Position output = identified position of the sensor + offset value.
The offset value is specified in digits. 1 digit corresponds to
10 µm.

•
Of sensor element 1 in mT. The value is recalculated every time
the element is overrun. Sensor element 1 is in the direction of
the cable outlet of the sensor.
•
Of sensor element 2 in mT. The value is recalculated every time
the element is overrun. Sensor element 2 is in the direction of
the sensor fixing screw.
Range of movement The range of movement describes the actual path traveled by the
pist
on.
Repeatability Repeatability is defined as any move to a preset position from the
same direction in every case.
MPS-G with 2/3 digital switching points and IO-Link (up to 16
switching points): The repeatability is typically 0.05 mm and
depends on the drive on which the sensor is mounted.
Resolution The sensor resolution describes the minimum, specifiable magnet
rout
e change as output by the sensor.
MPS-G with 2/3 digital switching points and IO-Link (up to 16
switching points): The resolution is 0.01 mm.
Sampling rate The sampling rate indicates the time interval in which the signal is
upda
ted at the outputs.
MPS-G with 2/3 digital switching points and IO-Link (up to 16
switching points): The sampling rate is min. 2 kHz.
Stroke speed in positive
direc
tion
Average measured speed of the piston in the positive direction in
m/s.
The positive direction goes in the direction of the sensor fixing
screw.
Stroke time in negative
direc
tion
Duration of the last stroke in the negative direction in ms.
The negative direction goes in the direction of the cable outlet of
the sensor.
One stroke corresponds to movement in a direction. Direction of
movement for retracting stroke: Start position - end position.
The start position is the direction of the cable outlet of the sensor.
The end position is in the direction of the sensor fixing screw.
