Enhance your P2S 3D printer with precision filament detection. The Bambu Lab Extruder Filament Sensor – P2S is a genuine OEM upgrade component designed to improve printing reliability by accurately detecting filament presence inside your printer’s extruder assembly.
Overview
This compact sensor module is engineered for installation on the upper portion of the extruder of the Bambu Lab P2S series. Its primary job is to monitor whether filament is correctly loaded and present — helping the printer react quickly to filament run-outs or feed issues that could otherwise compromise print quality.
Whether you’re replacing a worn part or adding improved filament detection to your workflow, this sensor is a simple, essential accessory for consistent 3D printing performance.
Key Features
- Reliable Filament Detection – Monitors filament presence at the extruder, reducing failed prints due to unnoticed run-outs or feed issues.
- Tailored Fit for P2S – Designed specifically to be compatible with the Bambu Lab P2S 3D printer series, ensuring seamless installation and function.
- Lightweight, Compact Design – Minimal footprint and weight mean it integrates without affecting printer ergonomics.
- Durable Construction – Built using robust plastic components for long-lasting performance in everyday printing conditions.
What’s in the Box
- Hall Switch Board Assembly × 1 — The core sensor unit that detects filament presence.
- BT2x5 Screws × 2 — Mounting hardware for secure installation on the P2S extruder.

The extruder filament sensor is a small but critical component in modern 3D printing:
Helps prevent wasted filament by detecting when filament runs out or fails to feed.
Ensures your printer can pause cleanly instead of printing air or errors.
A simple maintenance or upgrade part to keep your P2S running smoothly.
Designed exclusively for the Bambu Lab P2S model series — this sensor won’t function with other Bambu Lab printers such as the H2S, H2S Laser, or earlier P1 series without a specific matching sensor kit.
