Sensor strip for obstacle detection and connecting structure thereof

PURPOSE: A sensor strip for sensing an obstacle and a coupling structure thereof are provided to enable a molding operation to be easily performed since there is no cavity in a sensor body. CONSTITUTION: A sensor strip(100) for sensing an obstacle comprises a sensor body(110), strip electrodes(120,130), a PCB substrate, a protective case and a molding case. The sensor body comprises a reference surface(112), to which a target is coupled, and the inside of the sensor body is filled without a cavity. The sensor body comprises an insertion hole. The strip electrodes are laid in the sensor body in the longitudinal direction. A capacitive sensing circuit, which is electrically connected to the strip electrodes, is loaded on the PCB substrate. The protective case is mounted on the PCB substrate to cover the capacitive sensing circuit and is connected to the ground terminal of the PCB substrate.
