A distance detection induction device 100 comprises a housing 1, a condensing lens 2, a circuit board 3 having multiple electronic components, an infrared light emitting means 4, a light receiving means 5 for receiving and sensing the reflected infrared light. The housing 1 comprises a main body 10 and two round openings 11 and 12 on the top of the main body 10. The condensing lens 2 has an emitting lens 21 and a receiving lens 22 respectively located at the two round openings 11 and 12. The circuit board 3 bearing multiple electronic components for processing signal is mounted inside the main body 10. The infrared light emitting means 4 is to be infrared light-emitting diodes, emitting the infrared light to the emitting lens 21. The infrared light receiving means 5 is to be distance detecting sensing module, sensing the reflected light focused by the receiving lens 22. A connection part 23 having at least a bending part is set between the emitting lens 21 and the receiving lens 22. The distance detection induction device of the present invention has higher positioning precision and can enhance the induction performance of the whole device.
