RS Series Bearingless Absolute Encoder is mainly used for servo-driven control system.Provide feedback information and auxiliary signals required by accurate position and speed control units for the system.
.
Delivers ultra-high absolute positioning accuracy with up to 23-bit single-turn and 16-bit multi-turn resolution for precise rotary and servo applications.
Bearingless, compact architecture allows seamless integration in servo-driven control systems and limited-space industrial assemblies.
RS485 differential interface provides reliable, fast communication up to 2.5 MHz baud rate for demanding automation environments.
Resilient performance across a wide temperature range (-20°C to +105°C), with low current consumption (<100mA) and vibration/shock resistance.
User-friendly design supports a variety of shaft diameters (6mm, 8mm), multi-protocol customization, and robust power-loss resilience via battery backup.
