ThruSight-Theta Continuous Rotation Rotary Stage

ThruSight-Theta is an ultra-low-profile continuous rotation rotary stage engineered for high-precision automation, photonics, semiconductor, and life science applications. Its innovative ironless motor architecture delivers zero cogging torque, a large 110 mm through-hole aperture, and an industry-leading 25 mm overall height, providing exceptional motion accuracy, backside accessibility, and compact system integration. With 1 Nm of continuous torque and optional absolute encoder configurations, ThruSight-Theta is optimized for demanding move-and-settle applications requiring smooth, repeatable rotary motion.

Benefits & Advantages

• Ironless motor design that eliminates cogging torque for exceptionally smooth motion and more accurate positioning trajectories.
• Ultra-low 25 mm profile reduces system height, moving mass, and Abbe error for improved precision and easier machine integration.
• Provides immediate positional feedback upon power-up, with optional 1 Vp-p Sin-Cos analog, Digital AQB, and absolute encoder outputs.
• Compact, High-Performance Architecture
• Standard 3 m cables and multiple encoder configurations simplify installation into OEM automation systems.
