Abstract

Ce circuit est capable de fonctionner, sans modifications constructives, avec la grande majorité des capteurs existant sur le marché. Il est prévu quatre bornes d'entrées reliées à un circuit comprenant entre autres deux contacts et un transistor monté en série avec une diode électroluminescente faisant partie d'un photocoupleur relié à un étage amplificateur à transistor. Les capteurs sont raccordés à une borne d'entrée choisie en fonction de leur type et il suffit de positionner d'une manière déterminée les deux contacts pour que le circuit fonctionne toujours correctement Application aux capteurs pour le contrôle de la présence ou des dimensions de pièces.
