This sensor proactively pauses prints to save resources, making it an essential upgrade for professional and enthusiast 3D printing setups.

## Description

Product introduction:BIGTREETECH SFS V2.0 smart filament sensor is upgraded of BTT SFS V1.0, BTT SFS V2.0 is adopts high precise adopts photoelectric sensor whose theoretical detection length can reach up to 2.88mm, much shorter than 7mm of SFS V1.0. more accurate detection, detecting nozzle clogging, filament runout, filament tying, and extruder malfunctions, filament run s out or is broken, upgraded Bi-Directional Feeding, Status Light. It is the ideal choice for the 3D printer lamp to run/break detection module on the market.Calibration method :1. The theoretical detection length of 2.88mm is the amount of filament that will be extruded between each pulse of the signal. This means that if no filament movement signal is detected after 2.88mm of filament travel command, a filament error will be triggered. 2. Setting the detection distance to exactly 2.88mm may likely cause false triggers or errors. You can treat this parameter as the sensitivity of the sensor, the higher the number, the less sensitive the sensor will be. 3. The detection length needs to be adjusted depending on the mounting location of your SFS V2.0. The further away from the extruder, the higher the number will need to be. We recommend a starting point of 3mm. If you keep getting false triggers, increase the detection length by 1mm increments until the problem is resolved.SFS V2.0 Parameter：Dimensions: 53.1x30.3*27.3mmOperating Principle: Encoder+Pulley Set+Micro SwitchDetection Length: 2.88mm(theoretical detection length, may need adjustment）Compatible Filament: All 1.75mm filamentWorking Humidity: 10% to 90%Working Temperature: -10°C to 50°CRated Voltage: 3.3V-5VNet Weight: 36gSupport: Bi-Directional FeedingSupport: Filament Feeding LeverSupport: Status LightMounting Holes: Three mounting holes on the backMounting

Review: Works very well! I bought it with the expectation that I would have to mod it to work with the Anycubic Kobra S1 and I did. All I needed to do was make the 3 pole switch either HIGH or LOW instead of just open or closed. I then connected the wires to the printer and it worked flawlessly! It took some research and setting up but not as much as I thought it would.
Review: This sensor really saves prints. I tried to print some dragon using Silk PLA and I failed three times due to clogging. I decided to upgrade my printer and install this sensor and for now it paused my prints three times due to clogging but I was able to resume printing after clogging. So I'm continuing to print. Minor issue with sensor - you will need to mount them - I found the custom mount compatible with my print head (ender sprite pro) and printed them. P. S. The above is definitely a filament issue. I printed a lot without any clogging but glad to see I'm able to overcome filament clogging issue with this sensor.

*by F***A on 24 February 2026*

I have had two of these defective right out of the box. I would not recommend. The first one the encoder would not work consistently. I spent hours trying to figure it out until I replace it and the replacement worked fine. The second unit the switch circuit would not function. Unfortunately, my current setup and programming is designed to use this product. But, I will be redesigning to use something of higher quality.
