Product Description:

The 21BRCX-330-H7A is a high-performance resolver established by Danaher for use in industrial settings that require precise measurement of the rotor's angular position. It belongs to the Dynapar Resolvers series. It is made of steel to increase its reliability in tough industrial conditions. The resolver operates within a voltage range of 5V DC to 26V DC, so it is compatible with several industrial systems. This resolver weighs approximately 200 grams, and it is designed to work with rotors, thus improving strength while performing its functions. It has a standard MS-style industrial connection, therefore providing secure and reliable connections to the electrical input sources.

The 21BRCX-330-H7A resolver also provides sine and cosine analog output signals that are helpful in monitoring the position of the rotor. This makes it perfect for applications where the precise measurement of angles is crucial, including motor control systems, automation devices and robots. The resolver revolves at an excitation frequency of 5 - 10 kHz, which is higher as compared to most brushless resolvers, providing optimum performance and accuracy. Due to the analog signal outputs and the availability of a broad range of operating voltages, this type of microcontroller is suitable for many applications.

It is designed to work in harsh industrial applications. This resolver complies with IP65 standards for resistance against the penetration of dust and water. It has a working temperature ranging from -40C to +100C, and some resolvers support up to +120C. It is also shock resistant and can withstand up to 50 Gs for a short period. It is vibration-resistant and withstands up to 20 Gs within the 5-2000 Hz range. This 21BRCX-330-H7A is a robust resolver for demanding applications that require a longer life span and high accuracy.
