10BRCX-401-B1A/20 by Danaher

The 10BRCX-401-B1A/20 resolver from Danaher is part of the precision-focused Dynapar Resolvers series, engineered for high-performance industrial automation applications. This frameless device features a Basic Outer Diameter (frame Size) of 1.0 inches and a Housing Length of 0.65 inches, providing a compact profile that simplifies integration in tight spaces. Constructed with a robust Housing Material of steel and a Housing Type of Single Servo Groove, it delivers structural rigidity and reliable alignment in demanding environments. Configured for clockwise operation, the Rotation Direction is CW (Clockwise), optimizing compatibility with standard servo drive orientations. Classified under the System Type BRCX Single or Multi-Speed Rotor Primary, it supports both single- and multi-speed feedback for versatile motion control implementations. The resolver’s Size Rating of 20 ensures standard mounting dimensions, enabling seamless replacement or upgrade of existing rotary transformers without redesigning machine interfaces.

Performance and signal integrity are prioritized through a Wire Gauge of 28 AWG winding design that minimizes copper losses while delivering high-resolution output throughout an entire mechanical revolution. Rated for extreme conditions, it maintains full operational capability at temperatures up to 200°C, ensuring consistent performance in heat-intensive applications. A Lead/phasing Value of 12 provides precise electrical phasing, enhancing angle measurement accuracy and reducing signal distortion. The unit’s Multi-speed Availability yes allows automatic switching between speed channels, supporting both coarse and fine resolution feedback in dynamic motion systems. A Pilot Dimension of 1.04 inches facilitates concentric installation and ensures accurate coaxial alignment between the resolver and motor shaft. Optional Radiation Hardened Options Available provide added resilience in specialized environments where ionizing radiation may be present. The frameless construction delivers direct coupling to the motor shaft, reducing mechanical tolerances and eliminating the need for additional couplings or adapters.

Designed for robust reliability, the 10BRCX-401-B1A/20 achieves a Weight of 1.3 oz, contributing minimal inertial load and reducing overall rotating mass. Its simplified mounting mechanics—eliminating external frames—minimize points of mechanical wear and reduce assembly time, translating to lower maintenance demands. Without onboard electronics, the resolver resists electromagnetic interference and maintains signal fidelity in electrically noisy environments typical of industrial automation. Integration with standard servo controllers is straightforward, leveraging continuous sine/cosine outputs for real-time commutation of brushless servomotors and position feedback tasks. Ideal applications span precision manufacturing, robotics, packaging machinery, and material handling systems where compact size, high temperature tolerance, and multi-speed feedback capabilities are essential for sustained uptime and accurate motion control.
