VG 091A is the smallest ever  fiber optic gyroscope system (sensing optics and electronics in one housing)

Most sensitive and accurate in its size

Recently developed plastic frame is expected to bring to the VG 091A  even lower 30g weight and better bias behavior
Just +5V for full system performance

Lowest 0.5 W  power

Fastest 0.02 s start-up
Widest 1kHz    bandwidth

Lowest 30 gram weight

RECOMMENDATIONS AND PRECAUTIONS

 

1.	Do not deform housing
2.	Fragile components inside - no shocks, no drop
3.	Treat as electrostatic sensitive unit
4.	Is designed to be mounted inside water protected equipment
5.	Increased humidity shortens essentially lifetime
6.	Mounting surface must be grounded
7.	Power must be off during connecting
8.	Soldering to contacts - by low-temperature solder
