【Detects Filament Runout & Prevents Failed Prints】The Hall-effect filament sensor detects filament runout, jams, and feeding issues in real time. If filament runs out or a clog occurs mid-print, the printer pauses automatically, allowing you to reload or clear the jam and resume printing without wasting material or time. Prevents large-scale print failures caused by undetected filament problems.
【Resolves Common Sensor Faults】If your A1 or A1 mini frequently stops with filament errors, falsely reports unloading failures, or fails to detect filament during loading or printing, the sensor may be faulty or the ribbon cable damaged. Replacing the sensor with a high-quality replacement restores reliable filament detection and eliminates persistent error messages
【Easy DIY Installation】Replacing the filament sensor requires only basic tools (H2.0 and H1.5 Allen keys). Remove the printhead back cover, disconnect the ribbon cable, unscrew the old sensor from the 4-in-1 buffer, and install the new one. The complete process takes about 15 minutes and restores full functionality to your printer
【Your purchase includes two high-temperature silicone socks designed specifically for the A1/A1 mini hotend. These socks prevent heat loss around the heating block, help maintain stable extrusion temperatures, and protect the nozzle from accidental filament buildup. A simple accessory that improves print quality and simplifies cleanup2-Pack Silicone Socks Included – Protects the Hotend】
【2-Pack Sensor Kit – Spare for Future Maintenance】This bundle includes two filament sensors, giving you a spare for future maintenance needs. Each sensor is built to the same specifications as the factory-installed component, ensuring seamless compatibility with the AMS Lite multi-filament system and toolhead board. Reducing downtime when issues arise has never been easier

The Bambu Lab A1 Series Filament Sensor 2-Pack is a direct replacement component designed for the A1 and A1 mini 3D printers. This Hall-effect sensor monitors filament feeding status in real time, detecting runouts, jams, and clogs to prevent failed prints and material waste. When to Replace the Filament Sensor Common signs of a faulty filament sensor include: The printer stops mid-print with filament-related error messages. Filament is not detected during loading or unloading. False unloading failure reports appear even when filament is present. If you experience any of these issues, replacing the sensor with a high-quality replacement restores reliable operation. What's Included 2 × Filament Sensor (Hall board with FPC ribbon cable) 2 × High-temperature silicone socks for A1/A1 mini hotend The silicone socks protect the heating block, reduce heat loss, and keep the nozzle area clean. Easy Installation Replacement takes approximately 15 minutes. Remove the printhead back cover, disconnect the old sensor ribbon cable, unscrew the sensor from the 4-in-1 buffer, attach the new sensor, and reconnect the cable. Basic Allen keys (H2.0 and H1.5) are the only tools required. Refer to the Bambu Lab official maintenance guide for detailed step-by-step instructions. Seamless Compatibility Each sensor is built to match the factory specifications, ensuring perfect fitment with the A1/A1 mini toolhead board and full compatibility with the AMS Lite multi-filament system. This 2-pack bundle provides a spare sensor for future maintenance, minimizing printer downtime
