CRS04-01-PS CRS04-01-PS Rev. A (3/9) WARNING Limitations The product to which this specification refers is currently in development and is subject to change in design and performance. Some changes to performance parameters may occur as a result of ageing processes. The following limitations must be applied to avoid damage. Electrical Absolute maximum voltage +V = 6.0 V The unit has no protection against reverse polarity connection of the power supply. The positive rail is protected against transients of up to +6V. Mechanical Do not drop from more than 300mm onto a hard surface. Environmental -25 degC to +85 degC operation. SILICON SENSING SYSTEMS LTD. CRS04-01-PS CRS04-01-PS Rev. A (4/9) 1. DESCRIPTION The silicon vibrating structure gyroscope (Si-VSG) is a solid state single axis rate sensor. It is a stand alone unit with dc supplies and dc output proportional to the rate of rotation. The gyro is configured so that rate applied in a counter-clockwise direction, perpendicular to the plane of the pcb and viewed on the sensor head side, will cause the dc output to increase more positively. The gyro is operated with a unipolar power supply. 2. MODEL NUMBER CRS04 CRS04 - 01 Design Number: Variant 01 refers to a Non Ratiometric version, For other variants, see the relevant Product Specification Basic Model Number 3. MECHANICAL DESCRIPTION 3.1 EXTERNAL DIMENSIONS The dimensions of the gyro unit including the electronics for signal processing are: Height (Sensor Head) Length (Excluding Header) Width : Nominal 8.45mm (0.333 inch) Maximum 9.00mm (0.354 inch) : Nominal 30.0mm (1.18 inch) : Nominal 30.0mm (1.18inch ) Maximum 30.2mm (1.189 inch) Maximum 30.2mm (1.189 inch) Note: Dimensions in inches are for reference only. An installation drawing is given in Figure 1. 3.2 MASS The sensor, including its electronics, has a total mass of 11g typical (12g max). The centre of mass is within +/-1cm in all axis. 4. POWER SUPPLY REQUIREMENTS Operating voltage +4.85 to +5.15V Noise and Ripple DC to 100Hz :
