Product information & technical details


SFS V2.0 is a high-precision photoelectric filament sensor from Bigtreetech that provides error messages on the display when there are problems with the extruder, nozzle or filament and automatically pauses the printing process to avoid wasting filament. The sensor detects the following errors:

  • Clogged nozzle,
  • Running out of filament,
  • “Knotted” filament,
  • Faults or malfunctions on the extruder.

Real-time LED status display

SFS V2.0 is equipped with a coloured LED status display:

Flashing blue light shows that printing is going smoothly.

Constant red light shows that the filament is soon used up or broken - you are asked to react as quickly as possible.

Constant blue light shows that the nozzle is either clogged, an error has occurred in the extruder, or the filament has become tangled - you are alerted to react as quickly as possible.

Bi-directional feeding

With Bi-Directional Feeding, you don't have to worry about the orientation of the sensor as it detects both filament directions. This means you can quickly install the sensor and position it flexibly and in a space-saving manner.

Mounting holes for easy installation

The SFS V2.0 has three mounting holes on the back. With a bracket, the sensor can be easily installed on a printer. Suitable for both Direct Drive and Bowden extruders.

Wide compatibility

The filament sensor supports all motherboards with I/O ports (Endstop, Filament Detection, BLTouch, Induction Sensor, etc.).
