Product Description:

The 21BRCX-500-HC7 resolver is designed for industrial environment usage, offering very accurate positional feedback capabilities. It features an input voltage of 4.0 Vrms (±10%) which contributes towards its reliable performance. The device consumes 0.045 Watts of maximum input power, making integration with existing power solution easy. Its design allows usage through wide operational scenarios ensuring consistent results because of precise engineering. Weighing just 11 ounces, the resolver’s compact size facilitates simple mounting in different mechanical setting. This particular resolver supports an excitation frequency of 2.0 kHz (±5%), ensuring compatibility with many common industrial control systems through reliable functioning under variable constraints. The transformation ratio is 0.50 (±10%), confirming signal integrity, supporting precise control operations.

Focusing on important electrical characteristics, the resolver comes with an input current of 34 mArms max. It has an impedance (zso) of 247 Ohms, an impedance (zss) of 223 Ohms, an impedance (zro) of 152 Ohms, and finally, an impedance (zrs) of 135 Ohms. These impedance values enable the resolver to function efficiently while keeping the signal performance stable and predictable through varied operational conditions. The device features a DC resistance (r1-r2) of 38 Ohms (±15%) and a DC resistance (s1-s3, S2-s4) of 65 Ohms (±15%), crucial for maintaining consistent electrical performance. Because of this, the current through the device doesn’t suffer from changes, thus preventing device failures.

This resolver is built to withstand harsh conditions, performing flawlessly in an extensive temperature range of –55°C to 155°C. The accuracy of the device is reflected by its maximum error of ±7 arcminutes, an important attribute for applications requiring exact positioning. Its durable construction and dependable specifications makes it an excellent choice through many kinds of industrial applications where dependability and longevity are really needed. The 21BRCX-500-HC7 delivers both performance and reliable functionality in demanding industrial settings.
