PRODUCT OVERVIEW

High-rate performance.Flexible installation.

The FDA-114-STD is a single-axis rate table designed for development, production, in-process testing, calibration, and final inspection of inertial components and instruments, including high-precision MEMS sensors at FOG performance level.

The catalog emphasizes user-friendliness and competitive pricing. The system uses a highly reliable direct-drive servo architecture including a drive assembly, servo controller, and power amplifier.

The drive assembly consists of a direct-drive brushless torque motor, an optical encoder, a precision-machined tabletop, and a slip ring assembly. Precision, pre-loaded angular-contact ball bearings allow load capacities up to 25 kg.

All systems are supplied with the necessary interconnecting cables and mating connectors for the customer interface. Using T-Nut levelers, the rate table can be configured both vertically and horizontally and aligned in two directions.
