Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si 1. Adopt 12-bit high- magnetic encoder angle sensor. Compared with the potentiometer, the angle is expanded to 360degree , and the resolution is increased by 4 . Since there is a space between the magnetic encoder elements and the magnet, there is no friction, so the service life of the servo is effectively extended 2. The shell adopts the structural design of higher strength engineering plastic shell and double-axis low shell, 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 3. One-key calibration of the median, 360degree installation at any position, one-key to the current position to the median, very convenient for installation 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 . 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 require multiple steering gears, and can easily handle people Product Type: ST3215 Servo Bus Servo Product torque: 30kg.cm@12V angle: 360degree (0-4095) Position sensor resolution: 360degree /4096 Mechanism limit angle: Working voltage: 6~12.6V form: high metal No-load speed: 0.222sec/60degree (45RPM)@12V Encoder type: 360degree magnetic encoder ID range: 0~253 Baud rate: 38400bps~1 Mbps (default 1Mbps) Feedback: Position; Load; Speed; Input voltage 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 x 30kg serial bus servo Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
