High-precision angular velocity sensor utilizing
Murata's unique triangular prism vibrating unit.
No.S41E1.pdf 00.7.20
This is the PDF file of catalog No.S41E-1.
This angular velocity sensor employs the principle that the
Coriolis force results if an angular velocity is applied to a
vibrating object. Murata's unique triangular prism vibrating unit
is employed in the sensor element unit, thereby enabling
piezoelectric ceramics for both excitation and detection to be
used together. The employment of this unit simplifies
equipment structure and circuit configuration, thus making it
possible to maintain outstanding performance characteristics.
This sensor can be used for positional control and posture
control of a moving object requiring high-precision
measurements.
!FEATURES
1. Compact and lightweight.
2. High precision with high S/N ratio.
3. High sensitivity and good linearity.
!APPLICATIONS
1. Direction detection in vehicle navigation systems.
2. Controlling the direction of antenna facing satellite for
moving objects.
3. Detecting the movement of other objects for which high
precision is required.

!INSTALLATION
1. When installing the sensor, solder four tabs and terminals
on PCB (t=1.6mm). Observe the following rules. If not,
characteristics might vary due to soldering heat. Tabs can
be bent only once.
2. Install the sensor vertically with respect to the rotating
surface. (90

)
3. Install the sensor in a location free from vibration.
4. Install the sensor in a place with no substantial variations in
temperature.

Flow soldering
(in mm)
1. When high-precision measurement is required, as in a
navigation system, use the output of this sensor through an
A/D converter as shown above.
2. Positive voltage (
W
) and negative voltage (
Y
) are obtained
in the clockwise and counterclockwise directions,
respectively, with the static output as a reference.
3. An A/D converter of 12 bits or more is recommended.
Please choose a proper resolution according to the
application.
!NOTICE
1. Incorrect handling may affect sensor characteristics.
Please note the following precautions;
(1) Do not subject the sensor to shock that exceeds the
rated limit.
(2) Do not subject the sensor to a magnetic field exceeding
50 gauss.
(3) Do not install the sensor in a location in which
condensation is likely to from on it.
(4) Do not wash the sensor.
!NOTICE
2. Precision electronic parts, such as ICs and regulators, are
used for the sensor; therefore, it is necessary to take anti-
static measures when handling.
4. The sampling frequency is recommended to be 50 time/sec
minimum. Please choose a proper sampling frequency
according to the application.
5. Use a sensor output load resistance of 22k
or more.
