带PROFINET接口激光传感器 LDM42PN 激光测距传感器定义


The LDM41PN is an optoelectronic distance measuring device for industrial applications with integrated Profinet interface.
It works contact-free on the principle of comparative phase measurement (amplitude modulation) and facilitates precisely accurate measurement of distances.


Both, the LDM41PN and the LDM42PN distinguish themselves through high precision as well as high independence from the surface of the measuring object. The red, well visible laser beam allows for easy alignment. The LDM42PN has been further developed for fast distance measurements on white surfaces.
Through the integrated Profinet interface it is possible to read in data of several devices into a control easily. 


Applications
  • Distance measurement and determination of position
  • Diameter measurement of rolls / coils 
  • Fill level measurement 
  • Position control 
  • Monitoring of safety-relevant parts 
  • Monitoring of lifting plants / lifting height measurement and positioning of elevators
  • Monitoring and positioning of cranes and conveyor systems



  • Millimeter precise measurement on various surfaces 
  • High range reflector-less distance measurement 
  • With additional reflectors on the target object measurements over 100 m 
  • Operation in extreme ambient temperatures with high precision and range
  • High supply voltage range between 10 V and 30 V DC with low power consumption 
  • Safe operation through laser class 2 
  • Easy adjustment through visible laser beam
  • Common flexible interface cable for supply voltage, switching output and analog output
  • Direct connection to Profinet
  • Controlled by Profinet control byte
  • Customized parameterization via PC 
  • Display of measured values in meters, feet, inches and others due to free scaling
  • Robust, compact housing, easy to install, protection standard IP 65
