Optical 2½D TPS400 type testing system

The specialist system for type differentiation of round components


  • Designed for components with a maximum diameter of 400 mm and a height up to 70 mm (other sizes on request)
  • Maintenance friendly thanks to modular design, toolless exchange of components - in a few simple steps
  • LED ring lighting for perfect illumination
  • Inclusion of the height profile by using a line lasers
  • Designed for installation above the conveyor belt / component repository
  • Protected by a stainless steel cover
  • Stationary or operable whilst being able to be moved
  • Low-maintenance operation
  • Small space requirement

This is how the test is done

Procedure for testing

  • After depositing, the 1st - recording takes place with the integrated ring flash lighting
  • After that, a 2nd - recording will be created using an activated line laser for acquiring the height profile
  • The acquired component contours and component identification are compared with the data for the stored component types
  • The test result is transmitted to the PLC
  • Further test data are saved locally, if needed, or sent
