Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SER0053:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description When a servo is operated under complex circumstances such as robot and model, itmay get stuck, be burned or damaged due to external forces, which could bother you a lot... Now DFRobot is launching a series of servos with clutch function and electronic protection that can solve your problems perfectly. **Clutch Function** When the angle of a servo is changed by external forces during normal operation, the servo can automatically reset and continue working through clutch function, which prevents it from being damaged. **Electronic Protection** After being blocked for 5 seconds, the servo will automatically turn off its power to avoid getting burned. **Servo Internal Structure** ![9g 300° Clutch Servo](https://core-electronics.com.au/attachments/localcontent/1_23189c82f37.png) This servo features large torque, stable performance, accurate running angle and easy to install. The operating voltage is 4.8~6V. When the servo is powered at 6V, its stall torque will exceed 1.2Kg. There are no limited switches inside the servo so it can rotate smoothly in 360 degrees (manually only). Meanwhile, the servo could operate fluently with minimal power, and you can just supply power to it by normal battery or USB. In addition, users can directly control the servo using servo libraries in Arduino IDE and let it reach a maximum 300 degrees rotation angle within the pulse range of 500-2500µsec. **Mechanical Dimensions** ![9g 300° Clutch Servo](https://core-electronics.com.au/attachments/localcontent/2_124500f7c73.png) **Selection Guide for Clutch Servo** | **Selection Guide for Clutch Servo** | |---| | **Model** | **9g 180°** | **9g 300°** | **2kg 180°** | **2kg 300°** | | **SKU** | [SER0049](https://core-electronics.com.au/9g-180-clutch-servo.html) | [SER0053](https://core-electronics.com.au/9g-300-clutch-servo.html) | [SER0050](https://core-electronics.com.au/2kg-180-clutch-servo.html) | [SER0056](https://core-electronics.com.au/2kg-300-clutch-servo.html) | | **Operating Voltage** | 4.8-6V DC | 4.8-6V DC | 4.8-6V DC | 4.8-6V DC | | **Quiescent Current** | =8mA at 6.0V | =8mA at 6.0V | =8mA at 6.0V | =8mA at 6.0V | | **No-load Current** | =50mA at 4.8V =60mA at 6.0V | =50mA at 4.8V =60mA at 6.0V | =110mA at 4.8V =120mA at 6.0V | =110mA at 4.8V =120mA at 6.0V | | **Stall Current** | =550mA at 4.8V =650mA at 6.0V | =550mA at 4.8V =650mA at 6.0V | =700mA at 4.8V =800mA at 6.0V | =700mA at 4.8V =800mA at 6.0V | | **Rated Torque** | =0.32kgf·cm at 4.8V =0.4kgf·cm at 6.0V | =0.32kgf·cm at 4.8V =0.4kgf·cm at 6.0V | =0.45kgf·cm at 4.8V =0.55kgf·cm at 6.0V | =0.45kgf·cm at 4.8V =0.55kgf·cm at 6.0V | | **Stall Torque** | =1.0kgf·cm at 4.8V =1.2kgf·cm at 6.0V | =1.0kgf·cm at 4.8V =1.2kgf·cm at 6.0V | =1.6kgf·cm at 4.8V =2.0kgf·cm at 6.0V | =1.6kgf·cm at 4.8V =2.0kgf·cm at 6.0V | | **Operating Angle** | 180°±10° | 300°±10° | 180°±10° | 300°±10° | | **Pulse Width Range** | 500~2500µs | 500~2500µs | 500~2500µs | 500~2500µs | | **Communication Mode** | PWM | PWM | PWM | PWM | ### Specification - Operating Voltage: 4.8-6V DC - Static Current: =8mA at 6.0V - No-load Current: =50mA at 4.8V - =60mA at6.0V - Stall Current: =550mA at 4.8V - =650mA at 6.0V - Rated Torque: =0.32kgf·cm at 4.8V - =0.4kgf·cm at 6.0V - Stall Torque: =1.0kgf·cm at4.8V - =1.2kgf·cm at6.0V - Operating Angle: 300°±10° - Communication Mode: PWM - Pulse Width Range: 500~2500µs ### Parts List - 9g 300° Clutch Servo x1 - Servo Plate & Accessories x1 set ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/s/e/ser0053-1.jpg)
