SFS V2.0 - Filament presence sensor - runout and clogging - 1.75mm

SFS V2.0 is a smart filament sensor that enhances 3D printing reliability by leveraging a highly accurate photoelectric sensor to detect problematic filament issues like runout, tying and clogging.

Features Highlights:

• The SFS V2.0 is bi-directional, there is no restriction on filament direction, giving the users more flexibilit during installation.
• It detects extrusion errors caused by filament runout, nozzle clogging, filament tying and extruder trouble. It has two outputs and indicarto lights to distinguish between clogging or filament runout.
• Works with Marlin, Klipper and RRF firmware.
• Compact, lightweight and easy to install.
• Works with Bowden extruders and direct-drive extruders.
• Support motherboards with available endstop ports or dedicated filament runout ports.

Instruction:

• The filament can be threaded through either side of the SFS V2.0, as directionality does not affect functionality,
• The red light will illuminate when there is no filament in the module.
• The blue light will flash when the extrusion is normal.
• The blue light will stay on or off then there is no extrusion.

Specifications:

• Dimensions: 53.1 x 30.3 x 27.3 mm.
• Weight: 36g.
• Rated Voltage: 3.3V-5V.
