Product Description:
The 21BRCX-607-HG72A Resolver is an electromechanical device used to measure rotational position (angle) and sometimes speed which is made by Danaher. Danaher is a well-known company which manufactures industrial products for use in industrial automation.
This 21BRCX-607-HG72A resolver is designed to operate in environments with high levels of radiation and it won't degrade quickly under such conditions. All of its internal components are shielded against magnetic flux leakage which helps reduce electromagnetic interference (EMI), ensuring cleaner, more accurate signal output, especially in electrically noisy environments. The outer body of the resolver is made from strong materials like steel or aluminum which makes the module durable, corrosion-resistant, and suitable for both industrial and outdoor use. It supports different "speed" windings (e.g., 1-speed, 2-speed... up to 32-speed), where "speed" refers to the number of electrical cycles per mechanical revolution and the higher speeds offer finer position resolution, which is great for high-precision applications. It is able to work in extremely hot environments without failure which makes it well suited for industrial automation applications. The diameter of the part of the resolver that fits into a mating surface is 2.061 inches which is a standard size and ensures easy integration into existing mechanical assemblies.
This Dynapar Resolvers series model can be mounted using either a flange (a plate with bolt holes) or a servo-groove (a circular groove for precision fitting) which provide mechanical flexibility for different design needs. The module has exposed wire leads (pigtails) for hardwiring into a circuit or control system which allows for more flexible or customized integration into different systems. It can detect the rotor's position within a full 360-degree turn without needing to be referenced or zeroed at power up.
Frequently Asked Questions about 21BRCX-607-HG72A:
Q: Why is flux shielding important in the 21BRCX-607-HG72A resolver?
A: Flux shielding minimizes magnetic interference, improving signal accuracy in electrically noisy environments. It ensures stable output in systems with high EMI levels.
Q: How does radiation hardening benefit the 21BRCX-607-HG72A in industrial use?
A: Radiation hardening allows the resolver to function reliably in nuclear or space applications. It protects internal components from performance degradation caused by radiation exposure.
Q: What is the function of multiple speed options in this resolver?
A: Multiple speed windings allow for customized resolution levels. Higher speeds provide more precise angle detection in motion control applications.
Q: How does the 2.061-inch housing diameter simplify installation?
A: The standard pilot diameter ensures compatibility with common industrial setups. It reduces the need for custom mechanical fittings or adapters.
Q: Why are pigtail wire leads used in the 21BRCX-607-HG72A model?
A: Pigtail leads provide greater wiring flexibility for varied system layouts. They enable quick, customized electrical integration without the need for specialized connectors.
