15BRCX-500-J12

The 15BRCX-500-J12 resolver from Danaher is a precision rotary feedback device in the Dynapar Resolvers series designed for industrial automation and motion control applications. This compact unit weighs 4.5 ounces and features a robust steel housing with a length of 1.625" and a 1.440" pilot for seamless integration. It offers reliable counterclockwise phasing and is rated for AWG 24 wiring, ensuring compatibility with standard cable assemblies. With a nominal size of 12 inches and a velocity variation of ±7%, this resolver delivers consistent angular feedback without requiring digital encoding.

Technically, the 15BRCX-500-J12 resolves angular position via a BRCX system type with stator primary excitation, providing high signal clarity and stability. The resolver operates on an input excitation current of 55 mA at an input excitation frequency of 7 KHz, driven by an input excitation voltage of 4.25 Vrms. Electrical performance is further defined by a rotor resistance of 14 ohms and a stator resistance of 30 ohms, calibrated to optimize phase synchronization. A nominal phase shift of 4° enhances analog feedback loop accuracy and minimizes signal distortion. These characteristics combine to yield precise, low-noise output ideal for demanding control systems.

Operationally, the resolver’s single servo groove mounting and steel housing material ensure rugged reliability in harsh industrial environments. The housing length of 1.625" L with 1.440" pilot supports vibration-resistant installation in tight assemblies. A precisely machined rotor bore of 1/4 inch and rotor length of 1 inch guarantee accurate shaft coupling and minimal axial runout. This compact profile maintains mechanical rigidity while allowing real-time angle tracking, delivering high mechanical stability and low maintenance requirements. The design protects internal windings and electronics from contaminants, sustaining long-term operational uptime.

Integration of the 15BRCX-500-J12 resolver is straightforward in analog servo systems, where space constraints and reliability are paramount. Engineers benefit from plug-and-play compatibility with existing control architectures, supported by standard AWG 24 terminations. The resolver excels in machine tools, robotics, conveyors, and other automated equipment requiring robust, real-time feedback. Its combination of compact dimensions, precise electrical calibration, and industrial-grade construction makes it an exceptional choice for expanding motion control solutions across diverse applications.
