Bambu Lab Eddy Sensor - H2S

The Bambu Lab Eddy Sensor – H2S is a genuine OEM replacement sensor designed to detect whether melted filament has accumulated around or covered the printer nozzle. This nozzle-monitoring function forms part of the H2S toolhead’s sensing system and helps the printer recognize abnormal filament buildup around the hotend.

Replace the Eddy Sensor when the original component becomes damaged, experiences persistent sensor faults, or no longer provides reliable nozzle-condition detection. Installing the correct OEM replacement restores the original sensing hardware without requiring replacement of the complete toolhead assembly.

The package includes one Eddy Sensor and two BT2-6.5 mounting screws. It is compatible with both the Bambu Lab H2S and H2S Laser.
