Creality CFS and Filament Buffer Replacement Optical Sensors – 4 Pack

These replacement optical sensors are designed for use with the Creality CFS hub PCB and CFS buffer PCB. Whether you’re dealing with sensor issues or performing a DIY repair, these parts allow you to restore proper filament detection functionality.

The CFS hub PCB uses 4 sensors—one for each filament slot—while the buffer PCB uses 2 sensors. Installation involves desoldering the old sensors and carefully soldering the new ones in place. Be sure to match the sensor orientation, indicated by the angled face on the sensor body.

These sensors have been tested and verified to work 100% with our in-house K2 Plus + CFS setup.

⚠️ IMPORTANT: This product is intended only for individuals with soldering skills and proper equipment. TH3D Studio is not liable for any damage caused to your PCB during installation. If you’d prefer not to perform the repair yourself, you can contact us to send in your PCB for a professional repair service.
