Single Filament Sensor Replacement for P1P/P1S Printers
Includes P1P/P1S sensor, FPC cable, easy front-cover swap

This filament sensor replacement is designed for P1P and P1S printers. It sits in the extruder and watches for filament presence and the cutter lever status, helping prevent print failures and improving extrusion reliability. Its ideal for multi-color printing setups and material changes where runouts and jams can ruin a print.

Compatibility: Only compatible with P1P/P1S models, not X1 or other variants
Detects filament presence and cutter lever status to prevent unloads and jams
Supports multi-color printing; adjusts cutter detection as needed
Includes FPC flexible connection cable; PCB thickness ~1.2 mm; FPC ~0.12 mm
Easy swap: remove front cover, disconnect PTFE tube, loosen cutter lever, and replace sensor
