This sensor can stably detect at an ultra long range of 50 m (164.04').
When at this distance, it is generally very difficult to align the optical axis. Since the LV-H67 is a retro-reflective type laser sensor, installation is easy because it only requires that a reflector be placed in the area that the laser hits. This configuration allows long-range detection of reflective or even mirrored targets before they fall off the line.
