Product Description:

Danaher made the 11RC-300-D-22R/10 Synchro-resolver is a rotating transformer that can precisely sense angular position. The resolver is made to be used in systems that need accurate rotation control and reliable input. The resolver is often used in aerospace, defense, and industry automation systems to provide feedback to motion control systems.

The 11RC-300-D-22R/10 synchro-resolver has a 3/16-inch shaft diameter, which means it can work with a number of mechanical connections. The shaft is 1/2 inch long, which makes it easy to place and align. The six-wire leads that come with the resolver make it easier to connect to electrical systems that need differential signal outputs. The resolver can work in temperatures up to 125°C, which means it can be used in systems that are often exposed to high temperatures. This resolver is also used in closed-loop control systems for industrial robotics. Defense and aerospace systems use the resolver to get real-time data on their position, which makes targeting and tracking motion more accurate. The 11RC resolver is built so that it can transmit signals consistently even when it is mechanically rotating all the time. The 6-wire design keeps the signal integrity balanced between the stator windings and rotor parts.

The 11RC-300-D-22R/10 resolver has standard wiring for most resolver decoding systems. The resolver is designed to work with digital conversion units that convert analog resolver signals to digital position data. These specifications enable smooth system integration and position precision during dynamic motion control. The resolver is suitable for long-term rotation tracking. Due to its mechanical compatibility and high temperature tolerance, the resolver works well in embedded systems with restricted space and temperature. The resolver provides consistent feedback without recalibration when used routinely.
