This cutter material break detection PCB sensor is specially designed for Anycubic Kobra S1/S1 Combo 3D printers.It offers accurate compatibility and is ideal as a direct replacement for worn or original parts, helping restore normal filament detection performance.The PCB board accurately monitors filament status to detect material breaks, runout or feeding issues in real time.When abnormal conditions occur, the sensor can help trigger printer responses (such as pause or warning), effectively reducing print failures and material waste.Manufactured from stable, durable PCB materials with fine soldering and clear circuit layout, this sensor board ensures reliable signal transmission and long-term performance. It is engineered to withstand the continuous operation of 3D printers in daily use.Due to different batches, there may be differences in product appearance and printed text, which will not affect use.Color: BlackMaterial: PCBPackage Contents:1*Cutter Material Break DetectionOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
