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 UV print marks be recognized on textile black fabric?
How can UV print marks on black textile webs be reliably detected? With luminescence sensors from wenglor, reliable detection is possible even at high belt speeds. The P1PA001 luminescence sensor specifically excites UV markings and only evaluates their emission – for clear switching signals even on dark substrates.
