The RCH50 hollow-shaft encoder combines ease of installation with high performance. The foundation of this product is an incremental TTL encoder capable of resolutions up to 4096, but it has been designed to offer a wide variety of optional features to meet the needs of brush and brushless servo motor applications. Brushless applications can take advantage of the available outputs for motor commutation, implemented with precision optical logic to provide accurate switch points for smooth and efficient motor operation. The internal bearings and flexible stator coupling make installation on any motor absolutely hassle-free. High frequency response, robust construction, and the ability to operate in high temperatures allow the motor encoder package to reach higher levels of performance than possible with alternative technologies.
