Original for Bambu Lab Extruder Filament Sensor FAC142 for H2S – Genuine Replacement Part The extruder filament sensor h2s is a critical component located inside the h2s extruder assembly. This original fac142 sensor detects both the presence of filament and the position of the filament cutter lever, providing real-time feedback to your printer for reliable filament runout detection and automated ams switching - . Dual Detection for Smarter Printing Unlike basic filament sensors, this h2s extruder sensor monitors two critical states simultaneously. It confirms whether filament is properly loaded in the extruder channel and verifies the filament cutter lever position. This dual detection helps prevent failed prints caused by empty spools, filament breakage, or cutter mechanism errors. Essential Maintenance Part for H2S Owners The fac142 extruder filament sensor h2s is a consumable component included in the official h2s maintenance kit - . Over time, sensors may wear out or malfunction, especially after extended use. Replacing this genuine bambu lab h2s filament sensor restores your printer's ability to detect filament accurately and respond to runout events without delay. Plug-and-Play Hall Effect Board Assembly This h2s filament runout sensor comes as a complete hall effect board assembly with two bt2.6-6 screws included - . Installation is straightforward and takes about 20 minutes - . Simply remove the old sensor, disconnect the fpc cable, install the new fac142 sensor, and secure the cable connection. No soldering or complex calibration required. Compatible with H2S and H2S Laser This original fac142 extruder filament sensor is designed specifically for bambu lab h2s and h2s laser printers. It works alongside the printer's advanced sensor network, including the eddy sensor for nozzle detection and ams filament tangle sensor, to ensure smooth multi-material printing and automated filament backup.
