EMCORE releases MEMS IMU

EMCORE Corporation has  announced the introduction of the TAC-440 MEMS Inertial Measurement Unit (IMU), the world’s smallest 1°/hour IMU. Featuring an ultra-compact package of less than 5 cubic inches, the TAC-440 is a higher-performance, form, fit, and function compatible replacement for the Honeywell 1930 and 4930 IMUs.

The breakthrough performance of the TAC-440 IMU is based on EMCORE’s proven quartz MEMS inertial sensor technology. EMCORE’s quartz technology enables repeatable, high-volume production of precisely machined sensor structures combined with the inherent large signal output and thermal stability of quartz materials. The TAC-440 features 1°/hour gyro bias and 1 mg accelerometer bias stability with very low 0.05°/√hour Angle Random Walk (ARW) over a wide temperature range. It delivers outstanding performance over temperature, shock, and vibration environments with a Velocity Random Walk (VRW) rating of 32 µg/√Hz (τ=-1/2).

The TAC-440 IMU is designed for demanding, mission-critical, rugged environments in a wide variety of defense, commercial, industrial, and marine applications. The solid-state quartz sensors and hermetically sealed IMU construction provide reliable MTBF and storage life. Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection make the TAC-440 IMU easy to use in a wide range of higher-order integrated system applications.
