The Ultimaker Limit Switch Y Red Wire is an original spare part for the Ultimaker S5 3D printer. This limit switch detects the home position of the printhead along the Y axis, giving the printer the reference it needs for accurate, repeatable positioning at the start of every print job.

This part is the correct replacement when the S5 shows Y-axis homing errors, fails to home correctly, or moves erratically in the Y direction at startup. A defective Y-axis switch can cause the printhead to crash into the frame or result in prints that are displaced along the Y axis. The red wire colour coding distinguishes this Y-axis switch clearly from the X-axis variant and aids proper wiring during installation.
