	The triaxial kit includes three ARS-06 or ARS-06S sensors, three CA-06 cable assemblies, and a triaxial mounting block, which becomes a 6 degree-of-freedom (DOF) measurement system with 3 optional linear accelerometers added to its mounting surfaces. The ARS-06S uses a single-sided power supply commonly used in automotive crash testing. The type of linear accelerometers to be mounted must be specified at time of order to ensure correct mounting holes are included in the triaxial block. If none is specified, the block will be supplied predrilled for use with the Endevco model 7264B/7265 series accelerometers.		ARS-06 & 06S Triaxial Unit View .pdf format.
	The 3-DOF and 6-DOF Packages are 1.02 inches high and 2.1 inches on the diagonal. They’re small enough to fit inside the 12 month CRABI dummy head.
	Custom scale factors and ranges are available. ATA Sensors' patented MHD angular motion sensors utilize the finest materials and workmanship combined in durable packages that feature:
	• No moving parts • Dynamic range > 100 dB • Low power consumption • Low cross axis angular sensitivity • Low linear acceleration sensitivity • Integral electronics/low noise • Three mounting options • High survivable shock limits • Superior applications support • One-year warranty against defects in materials and workmanship on sensors, 90 days on cables.

Notes:

1. Based on a ± 10V output voltage swing.
2. Based on a ± 1.3V 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. Peak, 100 Hz half sine.
