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.	Mounting surface must be grounded
8.	Power must be off during connecting
9.	Soldering to contacts - by low-temperature solder
