          Multi-Purpose Digital Laser Sensor

          LV-N series

          LV-NH35 Small Beam Spot Reflective

          Small size and highly flexible installation

          Small beam spot through narrow spaces, the LV-NH35 laser sensor head

          Small Spot Beam

          A small beam spot can reach the target in a narrow space even at a detecting distance of up to 750mm.

          Constant Beam Spot Diameter

          The LV-NH35 retains a constant beam spot diameter at any point within its detecting range. This simplifies system design and setup significantly by eliminating the need to consider the sensor-to-target distance.

          The LV-NH35 Enables Highly Accurate Detection Regardless of the Installation Conditions

          By using a semiconductor laser as a light source, the LV series can maintain a sharp beam spot even at a long distance. Even when mounted far away from the target, the LV series can accurately detect and differentiate that which would have been impossible with a sensor using a LED as a light source.

          Cannon hole transmitter, LV-NH35 laser sensor head

          Cannon Hole Transmitter

          The LV-NH35 provides a coaxial structure in which the transmitter is composed of a metallic pipe from which the laser beam is emmited and the receiver is positioned around the transmitter to receive the reflected beam on the same plane. (Patent pending)

          (aiming at a target)

          Detecting grease in component

          With conventional reflective sensors, the reflected beam does not enter the receiver. However, the LV-NH35 provides the coaxial structure, enabling the reflected beam to be received.
