The Model 634 6-DOF Sensor is an analog sensor thatincludes outputs of three gyroscope/rate sensors andthree DC accelerometers in one small package. The ratesensors and accelerometers are aligned orthogonally toeach other which allow the user to measure motions in all
6 degrees of freedom (6-DOF). Designed specifically for
product research and development in harshenvironments, the Model 634 can maintain its precision
under high shock condition.
