The sensors can be distinguished by the number of independent integrated sensor elements, often also referred to as degrees of freedom (DoF). The product family includes a range of one-dimensional 1DoF gyroscopes, with their sensitive axis in or perpendicular to the assembly plane of the component (product types SD721, 751, 752, 757 and 758). The SD755 is a combination of a one-dimensional gyroscope and a one-dimensional accelerometer (2DoF). The sensors SD777, 778, 787 and 788 are a combination of one-dimensional gyroscopes with three-dimensional accelerometers (4DoF). SensorDynamics constantly adds new products to its portfolio. Two and three-dimensional gyroscopes combined with accelerometers are expected to be available shortly.
The combination of several sensor elements in a common package results in considerable cost savings for the application. For further optimization at the customer system level, most sensors provide two measurement ranges simultaneously and can be ordered as 5V or 3.3V version. As a special feature, all sensors are fail-safe: to this purpose an extensive and continuously working self diagnosis function has been incorporated across the product range. Also all sensors are AEC-Q100 qualified and offer a wide operating temperature range from -40 to +125°C.
