          Multi-Purpose Digital Laser Sensor

          LV-N series

          LV-NH300/NH100 Area Spot Thrubeam

          Unaffected by the target’s color or shape

          Optical Axis Alignment is Easy, Allowing the Detecting Area to be Clearly Viewed.

          LV-NH300/100 wide area thrubeam laser sensor

          Compact size. Four times smaller than conventional models

          World's Smallest in Class

          The optical system in the LV-NH300/100 series has been drastically improved compared to previous products. As a result, a small size suitable for general-purpose sensors has been achieved . The volume is reduced to a quarter* the size of previous models.

          Sharp linear beam created using a prism

          Linear Area Beam (Transmitter)

          A new optical configuration has been developed that uses a prism to provide a sharp linear beam. Wherever a target is passed within the sensing area, you will find that it is easily detected.(Patent pending)

          Diffusion sheet for easy optical alignment

          Light Diffusion Sheet (Receiver)

          A light diffusion sheet for beam confirmation is placed at the end of the receiver. While the sensor is being operated, you can visually confirm that the receiver receives the area beam..(Patent pending)

          Easily adjustable beam alignment

          Easy Adjustment of Beam Axis

          The optical system is drastically improved compared with previous products. As a result, a small size suitable for general-purpose sensors has been achieved for the first time ever. The volume is reduced to a quarter* the size of previous models.

          Largest assortment of laser sensor heads

          Industry Leader in Laser Sensor Development

          KEYENCE offers both thrubeam and reflective sensor types to provide a wide range of detection options . With the world's largest number of sensor head variations, KEYENCE laser sensors can meet the needs of any application.

          Applications

          Detection of Sagging or Breakage of Wire Rod

          Wire rod breakage

          The linear area beam allows the user to visually check whether the wire rod is present within the detecting area.

          Differentiation of Workpiece Length

          Screw length differentiated

          Differences in the screw length are differentiated based on the difference in the interrupted light intensity. Using two outputs enables you to detect the presence/absence of screws, in addition to differentiation of the length.


          Detection of Small Components

          Small component

          The visible beam enables you to easily adjust the sensor position. In addition, even if the target position varies, the sensors area beam can still perform detection.

          Differentiation of Workpiece Thickness

          Workpiece diameter

          The sensor differentiates between large and small diameter workpieces. By using two outputs, you can detect both the presence/absence of workpieces and differentiate between large and small diameter workpieces.

          Detection of Workpiece with Apertures (Spring)

          Apertures in workpieces

          The sensor's area beam ensures stable detection even if the workpiece has apertures.

          Detection of Incorrectly Assembled Components

          Thin component assembly check

          The sensor checks whether the component is incorrectly assembled. The visible laser spot allows for easy set-up even if the target is a thin component.

          Differentiation Between Front and Back Faces of Workpiece

          Reversed workpiece detectiont

          The sensor detects a reversed workpiece based on the difference in the interrupted light intensity. The visible area beam spot simplifies setup even when the clearance is small.


          Detection of Cutting Failure

          Uncut part

          The sensor with a 30-mm wide area beam reliably detects workpieces with a part left uncut.
