This filament runout sensor is perfect for any 3D printer build.  The sensor detects when filament is no longer present and pauses your print so you can add filament to your machine.  This sensor has a precision microswitch good for over 1 million filament changes.  The long 1 meter signal cable allows you to place it where it fits best for your build. 

Note that installation of a filament runout sensor often requires recompilation of your 3D Printer firmware to enable this capability.  

When installing this sensor be sure to check your wiring carefully.  Do not rely on the cable wiring to work with every mainboard.  Most 3 pin sensors use a S - Signal, G - Ground and V- Voltage in.  The photos here show how this sensor is wired.  Compare this to your wiring and your mainboard to ensure success when installing this sensor.
