KJT-KELR-TE20 High-precision laser ranging sensor

  • It can accurately measure the displacement change of the object to be measured.
  • Provide short-distance, high-precision specifications, suitable for applications requiring accuracy;
  • It meets applications where long distances still need to be measured, with the longest measurement distance up to 400 mm.
  • Meets the measurement applications of multiple types of product size, thickness, and shape.

  KJT-KELR-TE series laser displacement sensors adopt the triangulation measurement principle and use linear array CMOS devices as optical receiving devices. They have the characteristics of high measurement accuracy and short measurement time. The product optical path has been uniquely designed and the imaging quality is stable. ;With unique fill light technology

      (Note) The measurement conditions when not specified are as follows:

      voltage: 24V DC、

      ambient temperature:+20℃、

      Reaction time: 10ms、Analog output value for measuring center distance.

     Object:White ceramic. (Note 2): Based on the provisions of Laser Notice No. 50 of FDA regulations and based on FDA.

      This value is measured at the center distance. Define these values in terms of 1/e2 (approximately 13.5%) of the central light intensity. If there is light leakage outside the defined area and there are strong reflections around the detection point that are higher than the detection point itself, the detection results may be affected.

 relative to the direction of the moving body
<In case of material and color difference>
 When measuring, when the moving measurement objects have extremely different materials and colors, install them in the direction shown in the figure below to minimize the measurement error.

<Detect rotating objects>
 When measuring a rotating object, install it in the direction shown in the figure below to suppress the effects of vertical vibration and positional deviation of the object.

<When there is a step difference>
 If there is a step in the moving detection target, install it as follows to suppress the influence of the edge of the step during measurement.


 Measure in tight places and recessed parts.
 When measuring in a narrow place or hole, be careful not to block the light path from the emitter to the receiver when installing.

 When mounted on the wall
Please install according to the following methods to prevent multiple reflections from the wall from entering the light-receiving part. In addition, if the reflectivity of the wall is high, the effect will be better if it is changed to matte black.
