Fiber optic gyroscope VG103LN - the model equipped with a brighter light source and longer length of fiber sensing coil. The capacity of heat sink is increased to meet SLD power dissipation. The measures bring to the sensor 4 times lower noise.
For highly precise angular stabilization systems. The sensor has about 1kHz operating bandwidth and about 20ms start-up time. Optional blue light diode indicates power-on state.

RECOMMENDATIONS AND PRECAUTIONS
|
1. |
Do not deform housing |
|
2. |
Fragile components inside - no shocks, no drop |
|
3. |
It is recommended to use 2 diagonal screws with elastic washers for mounting |
|
4. |
Treat as electrostatic sensitive unit |
|
5. |
Is designed to be mounted inside water protected equipment |
|
6. |
Increased humidity shortens essentially lifetime |
|
7. |
