Series 21 Hollow-Shaft Rotary Optical Encoders
■Allied Motion's Series 21 are cost effective, hollow shaft optical encoders that are easy to mount and provide high data rate capabilities. These compact devices have their own bearing system and are enclosed in a high-grade glass filled plastic resin housing with an IP40 protection rating. The Series 21 provides significant performance benefits in applications that would be limited by traditional modular encoder solutions
■A flexible mount allows for much greater tail shaft runout and TIR than can be tolerated by other modular encoder designs.
■The Series 21 is capable of providing incremental digital (with commutation) or analog formats. And the incremental versions offer exceptional resolutions of over 2 million pulses per revolution
■The Series 21 encoders are also available in absolute formats. The new 16-bit binary or gray code absolute provides high measuring step count per revolution with low position error, enabling smooth drive performance and exceptional position accuracy. High bandwidth and noise immunity ensure excellent speed, stability, and command signal response in industrial environments.
■The Series 21 also supports the BiSS C protocol for incremental and absolute versions. This high-speed serial protocol is great for dynamic axes that require high acceleration, smooth velocity control, outstanding bi-directional repeatability, and solid positional stability.
■Programmable and easy to configure for a variety of output types, the Series 21 encoders simplify machine design by allowing the same model encoder to be used for a multitude of applications
●Features & Benefits
■Compact mechanical dimensions (2.1”O.D. x 1.2” H) for easier system integration
■Robust bearing system
■Industrial ball bearings enable up to 10,000 RPM shaft speed
■Simplified direct-mount design
■Software configurable resolution
■Circuit protection: Short circuit, reverse polarity, transient voltage suppression
■ASIC-based design for excellent matching and reliability
■Fast BiSS C serial data communications via RS-485 differential driver pair
■High noise immunity
■RoHS compliant
