<p>1. Adopt 12-bit high-precision magnetic encoder angle sensor. Compared with the potentiometer, the angle is expanded to 360degree , and the resolution is increased by 4 times. Since there is a space between the magnetic encoder elements and the radial magnet, there is no friction, so the service life of the servo is effectively extended</p> <p>2. The adopts the structural design of higher strength engineering plastic and double-axis low , optimizes the plane spacing of the double-axis rudder plate, and the overall structure is more compact, which can make the appearance of the product more beautiful</p> <p>3. One-key calibration of the median, 360degree installation at any position, one-key to correct the current position to the median, very convenient for installation</p> <p>4. The two-way feedback servo can feed back information such as position, load, speed and input voltage in real time, and control it at all times.</p> <p>5. When the voltage is 12V, the torque can reach 30kg.cm, which can be used to build four-legged, six-legged, robotic arm and other robotic projects that require multiple steering gears, and can easily handle large people</p> <p>Product Type: ST3215 Servo Bus Servo</p> <p>Product torque: 30kg.cm@12V</p> <p>Rotation angle: 360degree (0-4095)</p> <p>Position sensor resolution: 360degree \/4096</p> <p>Mechanism limit angle: </p> <p>Working voltage: 6~12.6V</p> <p>Gear form: high precision metal gear</p> <p>No-load speed: 0.222sec\/60degree (45RPM)@12V</p> <p>Encoder type: 360degree magnetic encoder</p> <p>ID range: 0~253</p> <p>Baud rate: 38400bps~1 Mbps (default 1Mbps)</p> <p>Feedback: Position; Load; Speed; Input voltage</p> <p>No-load current: 180mA</p> <p>Stall current: 2.7A</p> <p>Kt constant: 11kg.cm\/A</p> <p>Colour:black</p> <p>Material:Plastic + Metal</p> <p>Size: 45.22 x 37.25 x 24.72mm</p> <p>Package Contents:</p> <p>1 x 30kg serial bus servo</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
