Filament runout detection sensor module

Description

Filament runout / jam sensor module for 3D printers. It is placed in the filament path and toggles a digital output (HIGH/LOW) when the material runs out or the flow stops, allowing the controller to pause the print or trigger an alarm.

Features

• Digital output (logic level) readable by most 3D printer controller boards.
• Works from 3.3–5 V supply.
• Standard 3-pin connector: VCC, GND, SIG.
• Compact housing with mounting holes for frame/bracket (M3 or similar screws).
• Includes connection cable for quick installation.

General Specifications

• Supply voltage: 3.3–5 VDC
• Signal interface: digital (active on filament state change)
• Connector: 3 pins (VCC / GND / SIG)
• Mounting: 2 holes (M3 type)

Compatibility

Usable with most 3D printer control boards (e.g., Marlin, Klipper, etc.) that support a “filament runout” input.
