Product Description:
Danaher designs the 21BRCX-510-L12/2 Resolver to perform exact signal conversion functions in industrial automation. The resolver works at 7.5 kHz frequency while running under 26 Vrms excitation voltage. This requires ±5% tolerance control. The maximum input current level amounts to 45 mA.
The 21BRCX-510-L12/2 resolver achieves a transformation ratio of 0.454 with ±10% tolerance. It maintains a phase shift of 18 degrees. The electrical performance remains constant because this resolver maintains a DC resistance of 190 Ohms. This stays within ±15% of its nominal value. Its vibration stretches from 5 to 2000 Hz at 10 G’s. The resolver consists of a 0.8-inch bore diameter and a single groove design that enables the mounting operation. This resolver has an outer diameter of 1.35 inches as well as a maximum allowable weight of 11 lbs. The aluminum composition provides the housing of 21BRCX-510-L12/2 resolver with durable characteristics along with light construction weight. The resolver operates within an IP65 rating to block dust and prevent water penetration from entering. This resolver maintains both operational reliability and storage capability between –40 to +120°C and –40 to +130°C. This model functions optimally under shock levels reaching 50 Gs for 11 milliseconds.
The 21BRCX-510-L12/2 resolver exists for application in harsh operational environments. This resolver can operate with high accuracy when exposed to environments with 98% non-condensing humidity. The null voltage of the resolver maintains a 25 mVrms limit. The resolver provides a maximum acceptable position measurement error of ±10 ArcMin to ensure precise signal measurement. The dielectric rating of this case holds 500 VAC voltage but has a 2 mArms maximum value. This design allows installation into existing control systems through straightforward modifications. The Danaher resolver operating system fulfills positional measurement needs with stringent operating parameters.
