Sensor Fotoelétrico de Contraste de Impressão Pepperl-Fuchs DK12-11/124/136

Os sensores de contraste detectam as marcas de registro na impressão, conversão, embalagem, alimentos e bebidas, além de aplicações farmacêuticas para a classificação, posicionamento e controle de qualidade.


As principais características dos nossos sensores de contraste incluem sua capacidade em distinguir contrastes de alta resolução, tempo de resposta rápido, insensibilidade aos desvios de altura e ângulo em relação ao material identificado e óptica permutáveis. A seleção do transmissor de cor e o ajustamento do nível de desencadeamento ocorrem automaticamente.


Para aplicações especiais em ambientes agressivos, as versões DKE com invólucro de aço inoxidável e a versão RL5-LL com cabos de fibra ótica são recomendadas.
