The utility model provides a two-for-one twister broken yarn detecting device, comprising a yarn guiding ballon controller, a double twisting electric spindle, a cone yarn lifting device and an electric signal control panel. The utility model is characterized in that the yarn guiding ballon controller is disposed on the wallboard of the two-for-one twister; an infrared yarn detecting sensor is disposed on the yarn guiding ballon controller and is provided with a yarn detecting notch; the infrared yarn detecting sensor is connected to the electric signal control panel through a cable; the electric signal control panel is connected to the double twisting electric spindle and the cone yarn lifting device through a cable. The utility model is advantageous in that the reliable yarn detecting is ensured; non-contact yarn detecting is realized; the yarn hairiness is lightened; feedbacks of the signal are sent, controlling the on/off status of the double twisting electric spindle and the working status of the cone ya
