Product description

Toolhead Sensor FPC Cable – H2D / H2C is an original replacement toolhead sensor FPC cable for Bambu Lab H2D and H2C 3D printers (including Laser versions). It serves to connect the Hall sensors on both sides of the extruder tensioners and the front Hall board to the toolhead (TH) board, and is therefore key to the correct function of position and mechanism state detection in the printer head.

It is intended as a direct replacement for the original cable in case of its damage, breakage or short circuit, which can occur, for example, due to incorrect handling of the toolhead or rough folding of the wiring.

Technical parameters

Installation and recommendations

• Before replacement, turn off the printer and disconnect the power.
• Follow the official service manual / Bambu Wiki for H2D/H2C, especially when disassembling the toolhead covers.
• When handling the FPC cable, make sure not to bend it at a sharp angle and do not pull on the flex itself, but on the reinforced ends.
• After assembly, we recommend performing a test print and checking whether the printer reports any errors related to the toolhead sensors.

This part is suitable both for advanced users and service centers, as well as enthusiasts who want to have a quick replacement ready in case of unexpected damage to the cable in the printer head.
