UltiMaker Flow Sensor PCB Pack (S Series) 80-224396

Flow sensor PCB pack for UltiMaker S-series feeders

The flow sensor PCB pack is a critical maintenance kit designed to restore or upgrade the material monitoring capabilities of your UltiMaker S-series printer. These sensors are responsible for the "flow sensor" feature, which detects when filament has run out or if there is a blockage in the feeder system. By providing real-time data to the printer's firmware, these PCBs allow the machine to pause automatically, preventing failed prints and saving valuable material.

This comprehensive pack includes both the left and right sensor units along with all necessary mounting hardware. These components ensure that the internal optical sensors are perfectly aligned with the feeder's mechanical path, providing the high-precision detection required for professional-grade 3D printing.

Key features:

• Comprehensive kit: Includes both left and right flow sensor PCBs, plus all required springs, housings, and screws for a complete installation.
• Intelligent monitoring: Enables the printer to detect filament tension and movement, protecting your projects from extrusion-related failures.
• Precision alignment: The included housings and springs ensure that the PCBs are held at the exact tension and position needed for accurate optical tracking.
• Direct replacement: Manufactured to the original factory specifications for a perfect electrical and mechanical fit.

Note: These parts are only compatible with "fine" serrated feeders. They are not compatible with the older "coarse" serrated feeders phased out in 2021.
