ASSTech Instrumentation – Application Specialists in  Colour detection and measurement

The range of colour sensors, contrast and print mark sensors we carry cover a wide range of applications.  We have had much success in the motor industry, packaging and printing industries especially where the in-depth understanding of the principles of light and colour is necessary.  Call us to assist you!

WENGLOR Colour Sensor – Teach-in, FP04PCT80

WENGLOR Colour Sensor – Teach-in, FP04PCT80

  • Extremely fine color nuances can be recognized
  • Reflex mode operation
  • RGB signal via the RS-232 Interface
  • Teach-In and external Teach-In
This color sensor is capable of evaluating up to three colors simultaneously. A small spot and a large working range are made possible thanks to single-lens optics. All sensor settings can be selected by means of Teach-In, as well as via the RS-232 interface. Values generated by the sensor can be read out via the interface or digital switching outputs. The sensor has 3 PNP switching outputs and supplies RGB color values via the interface.

WENGLOR Print-Mark Contrast Sensor, WM03PCT2

WENGLOR Print-Mark Contrast Sensor, WM03PCT2

  • Compact Housing
  • Small Light Spot
  • Teach-In, external Teach-In, RS-232 Interface
  • White Light for recognition of any print mark combinations
These sensors have been specially designed to recognize print marks. They have a very small spot and use a white light LED with long service life. Only one sensor is required for the recognition of all color combinations, as well as the difference in brightness between print marks and the background.

WENGLOR Print-Mark Contrast Sensor, WP04PAT80

WENGLOR Print-Mark Contrast Sensor, WP04PAT80

  • Digital read-out of gray-scale values via the RS-232 Interface
  • High geometric resolution and very high contrast resolution
  • Teach-In, dynamic Teach-In, external Teach-In, RS-232 Interface
  • Very small spot: 1,4 × 4 mm
These sensors have been specially designed to recognize print marks. They have a very small spot and use a white light LED with long service life. Only one sensor is required for the recognition of all color combinations, as well as the difference in brightness between print marks and the background.
