The TL50 contrast sensor line offers the best solution for all the applications where cost reduction is requested, without compromising the excellent detection performances. The optimised optics of these sensors, the RGB LED emission with automatic colour selection and the very fine resolution, allow the detection of the weakest contrast of colours or grayscale between mark and background, or between different objects or surfaces. The high resolution is not a limit for the detection speed, reaching 33 ms response time and 15 kHz switching frequency. Thanks to the compact dimensions and multiple fixing holes with metallic inserts present in standard positions, the sturdy ABS plastic housing is fully compatible and can replace the most traditional contrast sensors, as well as offering an interesting cost reduction. The special PMMA plastic lens, that can be fixed either in an axial or lateral position, is suitable for sensor use in the food industry, where the presence of glass parts must be avoided.
