1. Features a 12-bit high-precision magnetic encoder angle sensor. Compared to potentiometer-based systems, offers a 360-degree rotation range and four times higher resolution. The non-contact design between the magnetic encoder and radial magnet eliminates friction, significantly extending servo service life. 2. Constructed with high-strength engineering plastic housing and a dual-axis low-profile design. Optimized internal spacing of the dual-axis output mechanism for a more compact and streamlined structure, enhancing overall appearance. 3. One-key centering calibration allows 360-degree installation positioning. Easily set the current position as the neutral point with a single button, enabling convenient and flexible installation. 4. Bidirectional feedback system provides real-time data on position, load, speed, and input voltage, allowing for continuous monitoring and precise control. 5. Delivers up to 30kg.cm of torque at 12V, suitable for multi-servo robotic applications such as quadruped, hexapod, and robotic arm projects. Capable of handling high-load tasks with ease.
