21BRCX-601-H42/10

21BRCX-601-H42/10 is a Danaher resolver from the Dynapar Resolvers series. Its basic outside diameter is 2.1 inches, and the aluminum housing is 1.06 inches long. The aluminum construction provides a lightweight enclosure for the resolver components. A single servo groove supports installation in a compatible mounting assembly, while the 2.061-inch pilot diameter helps align the resolver during mounting. The rotor has a 0.5-inch keyed bore for engagement with a keyed shaft, and its sleeve is 1.06 inches long.

The resolver accepts a 4 Vrms input at 25 mA, providing the electrical excitation required for position sensing. Its excitation frequency is 5 kHz, which establishes the operating frequency of the input signal. The transformation ratio is 0.50, so the output voltage is nominally one-half of the applied excitation voltage under the applicable measurement conditions. A phase shift of -6 degrees indicates that the output signal lags the excitation reference by 6 degrees. Null voltage is 25 mV, representing the residual output when the resolver is at its electrical null position. Peak-to-peak error is 10 arc-minutes, indicating the total angular deviation across the measurement cycle. Electrical connections use 24 AWG lead wire with a 12-inch lead length for routing to the associated control or measurement equipment.
