Linear Array Detector
DR500 / EM

  • High detection accuracy
  • Detection of hot or cold products
  • Design for extremely harsh environment
  • Detection regardless of the transverse position

Typical applications

The receiver DR500 is a light grid detector. In association with the EM•-C LED emitter, it is able to detect hot or cold products in a wide field, whatever the transverse position of this product.
The DR500 allows a detection at a very high speed on a very narrow line, like a scanning sensor. The product can be from ambient temperature up to 1350°C.


Detection of small bars (hot or cold) on a wide table







            Detection of head / tail (hot or cold)


Main features

The detector DR500 consists of a lens, a linear diode array and a processing unit enclosed in a cast aluminium case.
The image of the viewed area is focused onto the diode array. The output of the Detector DR500 switches when a product is seen within the field of view with light emitter EM•-C in the background.
The detector DR500 has been designed for heavy industry, with a mounting stand, which is adjustable in two axes. In case the sensor must be replaced, it can be easily dismounted from the stand, without disturbing the alignment.

 The control panel allows an easy setup and includes:

  • 3 LED giving sensor status:
    • P.P. is green when detection output is activated (Product Presence)
    • Ctrl is orange when detection margin is not enough.
    • Alarm is red when alarm output is activated (internal T° too high, receiver out of function)
  • A bargraph with green LED showing the active field of detection and position of the product within this field.
  • A ‘Field’ potentiometer to set the detection angle.
  • A ‘Sens./Laser’ potentiometer to adjust sensitivity.
  • A green laser cross, to make easy alignment, is activated at power ON and as soon as you turn the ‘Sens./Laser’ potentiometer (stays ON during 15 min, then automatically switches OFF).




  • Stainless steel heat shield for receiver DR500



  • Additional cooling plate for receiver DR500



  • Cooling plate for emitter EM•-C (multiple plates can be mounted on emitter for higher efficiency)



  • Adjustable mounting support for emitter EM•-C



  • Junction box to connect DR•500 and EM•-C



  • Power and I/O cable between junction box and DR•500 and EM•-C, with protective metallic braid
