          Multi-Purpose Digital Laser Sensor

          LV-N series

          LV-S31 Small Beam Spot Reflective

          Small size and highly flexible installation

          LV-S31: Unaffected by Targets' Color

          No readjustment needed for tooling change

          Since the LV-S31 detects based on target height or position, and not color, it will not have to be readjusted when the color of a target changes.

          LV-S31 Series Adjustable Distance Detecting Head Laser Sensor

          Light receiving element: Dual Photodiode

          Light receiving element: Dual Photodiode


          Dual Photodiode

          The dual photodiode (PD) receives the reflected beam spot from a target and focuses it onto the dual PD. By adjusting the trimmer, the reflected spot can be centered so that half of the spot is on the NEAR PD, and half is on the FAR PD for a 1:1 ratio. As the target moves closer to the head, the reflected beam spot shifts more toward the NEAR PD and the displayed value will decrease. As the target is moved away from the head, the spot shifts toward the FAR PD and the displayed value increases. By detecting based on distance and not brightness, the LV-S31 can be set to detect that a part is not only present, but that it is in the correct position, regardless of the surface color.

          Adjust setting to optimum conditions without relocating sensor - Adjustable Structure

          You can adjust light receiving element to optimum conditions by simply rotating the adjustment trimmer.

          Adjust setting with a sensor head

          Adjust setting with a sensor head

          The sensor head is equipped with an output indicator and position indicator that indicates the distance with a target. This makes it easy to adjust the settings online if the amplifier is not easily accessible or visible.

          Distance - Hysteresis (Typical)

          Hysteresis when the light receiving element and the setting value are adjusted to 5000 at each distance.

          Color canceling function

          Dual photodiode and original algorithm correct color influence of a target that is displaced from the center.

          Long-range gap detection

          Long-range gap detection

          The LV-S31 can detect a 0.04" (1 mm) gap at a distance of 7.87" (200 mm) and a 0.02" (0.5 mm) gap at a distance of 1.97" (50 mm). (Target: White paper, response speed: SPED4 at ambient temperature) *Maximum detecting distance varies according to target's reflectance
