Product Description:
The 21BRCX-621-JA84/15 Dynapar Resolver is a high-performance motion-sensing device manufactured by the company Danaher that is extensively used in industrial automation and control mechanisms. It runs at an excitation frequency of 7.5 kHz ~ 5% and has an input voltage of 6.0 Vrms ~ 10%, providing mechanical stability and precise operation. It has a maximum input current of 55 mA and an input power of 0.15 W, hence, it is recommended for a wide range of applications due to its low power consumption.
This resolver has high impedance values, where Zro is 129 Ohms, Zrs is 113 Ohms, Zso is 81 Ohms, and Zss is 70 Ohms. The demodulator has a transformation ratio of 0.28 (+ or - 10%) to enable efficient signal transmission for position tracking accuracy. Moreover, it has a relatively low DC resistance of 35 Ohms (r1-r2) and 11 Ohms (s1-s3, S2-s4), which means signal loss is negligible. This type of resolver can work with an error of ~ 15 arcminutes and has a phase shift of -1 in an open circuit, which makes it useful for providing reliable and accurate motion control information in industrial instruments and automation devices.
Built to withstand the rigidity of working environments, the 21BRCX-621-JA84/15 operates in areas with a temperature of - 55C to 155C, making it durable and reliable in its operations. It has a maximum null voltage of 20 mVrms, which helps in improving accuracy through the reduction of signals that may interfere with the measurement. Due to its solid structure and high accuracy, this Dynapar resolver is appropriate for applications requiring accurate and optimal motion control, including robotics, aerospace, and manufacturing equipment.
