Delta USAV5
Laser Reflecting Barrier
Detection of Hot and Cold Products


       
Application 
The V5 laser reflecting barrier resolves all detection problems that may arise in the most diverse types of industry, for example heavy industry (steel), handling and transport. The use of visible emission greatly facilitates setting up of the barrier.

General Description 
The V5 is a self-contained sensor including: 

  • an optical unit equipped with laser diode and reception photodiode
  • an amplifier with output interface (solid state or relay output)
  • connection via a terminal block with protective cover or via a connector





     
Working Principle
A laser beam of visible modulated light is emitted by the laser emitter and reflected back along the same path by a prism reflector placed opposite to the sensor. The reflected beam is focused onto the photodiode which outputs an electrical signal to the amplifier circuit. Depending on whether the modulated beam is interrupted or not, the output is switched. Modulating the emission and automatic correction for ambient light in the amplifier circuit makes the sensor insensitive to ambient light.
   

Special Features

  • Visible laser beam (class II)
  • Insensitivity to ambient light 
  • A sensitivity potentiometer for adjustment of the detection threshold (under the protective cover at the rear of the sensor)
  • Jack socket (under the protective cover at the rear of the sensor) providing an output of signal level as an aid during alignment
  • A LED indicator showing operation of the sensor
  • An optional water-cooling plate for use at ambient temperatures greater than 70°C (flow-rate 2 I/mn)
  • Modular construction allowing rapid maintenance
