- Page 1 OPERATION MANUAL GYROSTAR Piezoelectric vibrating Gyroscope MODEL : ENC-03M TYPE January 13, 2004 PRODUCT ENGINEERING SECTION SENSOR MODULE DEPERTMENT CIRCUIT PRODUCTS DIVISION MURATA MFG. CO., LTD.
- Page 2 This angular velocity sensor utilizes a Coriolis force that act on a vibrating object when an angular velocity is applied to it. Murata's unique ceramic bimorph vibrating unit is used as the sensor element unit, thereby enabling piezoelectric ceramics to be used for both excitation and detection.

ENC-03M type 3. Terminal Terminal Symbols Descriptions M JPN Vref Reference voltage (approx.+1.35V) MA 315 Ground Supply voltage Sensor output 4. Connection 1) Operation voltage is +2.7V to +5.25V. Use a stabilized power supply free from surge and ripple voltages. Also, confirm proper power supply polarity before connecting sensor. - Page 5 ENC-03M type 6. Instruction for use 1) One sensor can detect one angular velocity along one axis. You need two sensors when you want to detect around 2 axes angular movement. 2) Install sensors in a direction that the rotating axis is parallel to long side of the sensor. CW(+) CCW(-) 3) There are 2 types of sensors.
- Page 6 ENC-03M type 5) Do not install sensors near vibration source such as actuator or buzzer. It may have an affect on sensor output when vibrating frequency or their harmonic component is near by resonant frequency of gyro. 6) Temperature variation will have an affect on the sensor output in bias, scale factor. Sensors should be mounted where ambient temperature would not be likely to change.
- Page 7 ENC-03M type 3) Usually an A/D converter of 8 bits or more is used. Resolution of A/D converter will affect measurement accuracy. Please choose a proper resolution according to the application. 4) The sampling frequency used for measurement should be 50 times/sec minimum. Sampling frequency will affect measurement accuracy.
