Product Description:

The R561024100322 resolver is manufactured by Danaher and belongs to the Dynapar Resolvers series. It is a shaft-mounted feedback device that converts mechanical rotation into differential electrical signals used by motion controllers for position and velocity monitoring in industrial automation. By delivering incremental ABZ channels, the unit supports closed-loop regulation of servomotors, conveyors, and robotic joints where accurate phase tracking and index referencing are required.

The resolver accepts a supply between 5 VDC and 26 VDC, allowing the same model to be powered from logic-level rails or higher auxiliary buses in multi-axis drives. Input current is limited to a maximum of 80 mA, while the 7272 differential line driver can sink or source up to 40 mA per channel. With a maximum output transition rate of 120 kHz, the device maintains clean square-wave edges even at elevated shaft speeds, and its electrical phasing of 90° ± 22° preserves quadrature integrity. Screw terminals provide serviceable electrical connections without requiring a dedicated plug assembly. For counterclockwise rotation, channel A leads channel B to establish the phase direction used by the connected controller.

The resolver supports a maximum speed of 5,000 rpm, keeping feedback frequencies within the tolerance of compatible drives. Each revolution produces 1,024 PPR, giving controllers 0.35° native resolution before interpolation, while the 270° electrical index supports automated homing. A symmetry window of 180° ± 54° electrical balances the signal duty cycles and minimizes timing skew between transitions. The unit withstands shocks of up to 50 G for 11 milliseconds, making it suitable for press or gantry installations that experience brief mechanical impacts. A stainless steel sensing wheel with a 1-inch bore mounts directly on standard motor shafts. Set screws secure the wheel and help prevent slippage during rapid changes in rotational direction.
