The ARS-09 is a versatile angular rate sensor that offers an economical price while meeting the shock and acceleration limits required in most general motion testing methods. It exhibits a high sensitivity with low to moderate angular range. Originally designed for automobile suspension analysis and machinery monitoring applications, the ARS-09 is small enough to be mounted in compact spaces and has an integral cable assembly. The ARS-09 is available in two standard models: the ARS-09 and the ARS-09S.

Custom scale factors and ranges are available.

Notes: 1. Based on a ± 10V output voltage swing. 2. Based on a ± 3.5V output voltage swing. 3. Measured @ 10 Hz. 4. The standard frequency response of MHD sensors can be extended significantly by the use of digital filtering in post processing of signal data as covered in ATA Sensors' application note AN-01.	5. Power spectral density flat to angular velocity over specified bandwidth. 6. Percent change in Scale Factor per ºC @ 100 Hz. 7. Signal return connected to case (isolated from mounting flange). Do not ground case to mounting fixture to avoid ground loops. 8. Peak, 100 Hz half sine.
