Specifications of output data

scroll
Data name Description
Distance data Indicate the 3D distance between B5L’s coordinate origin and the target object
Distance data in the form of orthogonal coordinate Xo, Yo, Zo: XYZ coordinates with the coordinate origin as the origin
Distance data in the form of orthogonal coordinate rotation Xr, Yr, Zr: Orthogonal coordinates after rotating around axes Xo, Yo, Zo at an angle set by the command
Distance data in the form of polar coordinate r,θ,φ Polar coordinates based on orthogonal coordinates
Amplitude data Light-receiving sensitivity of each pixel when LED is illuminated
16 bits (256 gradations)
Note 1. Refer to User’s Manual (Manual No.: E596-E1) for details
Note 2. When the form of orthogonal coordinate or orthogonal coordinate rotation is specified, the distance data will be outputted in the form of PCD (Point Cloud Data).

Precautions for Correct Use

Observe the following precautions to prevent failure to operate and malfunctions, and to prevent adversely affecting the performance and function of “the Product”.

  • Store the Device at a temperature of -20°C to +60°C and a relative humidity level of 35% to 85%.
  • Do not touch the board mounted parts with bare hands. Discharge any static electricity from the user before use.
  • Take proper measures against static electricity by using an antistatic wrist strap, etc. before handling “the Product”.
  • Make sure to properly ground the connector's earth terminal in order to prevent malfunction due to noise.
  • Do not use “the Product” in places where the surrounding temperature goes above the rating range.
  • Do not use “the Product” in a location where it would be subjected to direct sunlight.
  • Do not use “the Product” in a location subject to excessive inductive or power supply noise, such as in strong magnetic or electric fields.
  • Do not use “the Product” in a location where it would be subjected to strong UV light.
  • Do not use “the Product” in a location where it would be subjected to radiation.
  • Sufficiently evaluate the electrical characteristics of any connection to the Device.
  • If the Customer designs such structures as NIR transmission filter and installs them in front of the light-projecting part or the light-receiving part, the detection performance will deteriorate due to NIR light transmittance. Therefore, design with margins giving consideration to deviation and other factors.
  • The Customer should choose the power cable and USB cable after fully validating their applicability.
  • Do not strongly pull the cable connected to the Device.
  • Do not reversely insert the Connector.
  • Do not forcibly insert any non-standard connector.
  • Do not touch the light-projecting part or the light-receiving part.Clean the light-projecting part or the light-receiving part iffouled. Clean with a soft and dry cloth, avoiding damage to thelight-projecting part or the light-receiving part. Never usevolatile solvents such as benzine and thinner or chemicalwipers, etc.
  • In order to improve long-term reliability of the Device, paysufficient attention to heat emission during installation.
  • Install “the Product” at a sufficient distance from surroundingheat generating parts.
  • When installing “the Product”, do not block the top surface,side surface and heat sink surface of the Device. Otherwise,heat cannot be emitted.
  • “The Product” generates heat during operation. Since thesurrounding temperature rises due to heating, sufficientconsideration should be given to heat emission so that thesurrounding temperature will not go above the rating temperaturerange. In addition, do not fix “the Product” upside down.
  • In case of instantaneous stop or power outage, when power isrestored, make sure to use “the Product” after resetting.
  • If abnormality occurs in received data, restart the power or reset.
  • Do not peel off the QR code label. Otherwise, lot tracing of “theProduct” will become impossible.
  • Do not use “the Product” under conditions where it would besubjected to strong interfering light.
  • If multiple units of “the Product” are used simultaneously,measurement may not be performed correctly due to theinfluence of NIR light transmitted from sources other than theDevice.
  • Before using “the Product”, fully confirm if “the Product” can beused at the actual installation location.
