for Position
Measurement
Series MUK 350
Special features

sensors
• Aluminium die-cast housing;
Protection class IP 66
• standardized output signals
0 ... 10 V
± 10 V
0 ... 20 mA
4 ... 20 mA
• outstanding linearity
• extremely low temperature
drift 30 ppm/K (typical value)
• zero point and range adju-
stable
The signal conditioner sup-
plies the position sensors with
a highly stable constant volta-
ge. The wiper signal is picked
off without load via a high-
resistance input stage and
transformed into a displace-
ment or rotationally proportio-
nal standardized output sig-
nal.
The excellent linearity, low
temperature drift and sensor-
proximity of the signal con-
ditioning process ensure full
utilization of the outstanding
benefits of the position sen-
sors, guaranteeing the relia-
ble, interference-free transmis-
sion of signals even over long
distances.
The zero point and range can
be adjusted independently of
each other within wide limits
using spindle trimmers. This
facility permits standardized
output signals to be adjusted
even if the maximum stroke /
angle of the sensor is not
completely utilized. The elec-
tronic circuitry is accommoda-
ted in an aluminium die-cast
housing conforming to protec-
tion class IP 66. The UNI-sea-
led threaded joint ensures a
correct EMC coupling of the
cable shield. The wide opera-
ting voltage range allows the
unit to be supplied with an
unstabilized direct voltage
source. Selected SMD com-
ponents with a wide tempera-
ture range guarantee maxi-
mum operating reliability even
under extreme environmental
conditions.
The MUK 350 is connected
by means of a four-pole termi-
nal strip.

* The TC applies for current and voltage outputs. If the voltage is picked off at the load resistor,
the TC of the resistor must also be taken into account.
