Adopt 12-bit high- magnetic encoder angle sensor, expanding the angle to 360 degrees and increasing the resolution by 4 times compared to potentiometers. The shell is designed with high-strength engineering plastic and a double- low shell, optimizing the plane spacing of the double- rudder plate. One-key calibration of the median allows for 360-degree installation at any position, easily correcting the current position to the median. The two-way feedback servo provides real-time feedback on position, load, speed, and input voltage, ensuring constant control. At 12V, the torque reaches 30kg.cm, suitable for building robotic projects such as four-legged, six-legged robots, and robotic arms requiring multiple steering gears. Product torque: 30kg.cm@12V Rotation angle: 360degree Working voltage: 6~12.6V No-load speed: 0.222sec/60degree (45RPM)@12V Encoder type: 360degree magnetic encoder ID range: 0~253 Baud rate: 38400bps~1 Mbps (default 1Mbps) No-load current: 180mA Stall current: 2.7A Kt constant: 11kg.cm/A Colour:black Material:Plastic + Metal Size: 45.22 x 37.25 x 24.72mm Package Contents: 1*Servo-Motor Kit Only the above package content, other products are not included.
