Detect and distinguish object colors with contrast sensors
RGB contrast sensor P1PW specifically detects colors, color families and fine nuances. Ideal for print marks, color control, and changing object colors.
Precision on shiny surfaces: reliable detection of black markings
Detecting black markings on shiny copper or brass is a challenge for many sensors. This article shows how the compact YM24 contrast sensor reliably detects even manual markings on reflective metal strips thanks to its long range and high switching frequency – while offering maximum flexibility in terms of vibrations and tight installation space.
How can I reliably align transparent tubes?
Aligning transparent or lightly printed tubes reliably is often a challenge in filling systems. The article shows how P1PW contrast sensors with white light, RGB evaluation and automatic light control reliably detect even the smallest print marks or structures – and thus enable precise, stable tube alignment.
What reflective properties do colored surfaces have – and how do sensors work with them?
Colors are created by the interaction of light and the reflective properties of a surface. The article explains how colored materials reflect and absorb light – and how modern sensors use this information to precisely detect colors. Ideal for use in quality control, robotics and color measurement.
