Abstract

UN INTERRUPTOR FOTOELECTRICO DE TIPO REFLECTANTE PROYECTA LA LUZ EMITIDA DESDE UN ELEMENTO EMISOR DE LUZ HACIA UNA ZONA DE DETECCION, MEDIANTE UN SISTEMA OPTICO DE PROYECCION DE LUZ, Y GUIA LA LUZ REFLEJADA DESDE UN OBJETO QUE SE VA A DETECTAR EN LA ZONA DE DETECCION A UN ELEMENTO RECEPTOR DE LUZ, MEDIANTE UN SISTEMA OPTICO DE RECEPCION DE LUZ. UN ELEMENTO OPTICO ESPECIAL SE UTILIZA EN PARTE, DE AL MENOS UNO DE LOS DOS SISTEMAS OPTICOS. EL ELEMENTO OPTICO FUNCIONA PARA HACER DIVERGIR LA LUZ EN UNA DIRECCION PARALELA A UN PLANO QUE CONTIENE LOS EJES OPTICOS DE LA EMISION DE LUZ Y ELEMENTOS RECEPTORES DE LUZ, Y CONDENSA LA LUZ EN UNA DIRECCION PERPENDICULAR AL MISMO PLANO. EN CONSECUENCIA, ES POSIBLE DETECTAR, CON EXCELENTE SENSIBILIDAD, TANTO UN OBJETO QUE ESTA LEJOS DEL INTERRUPTOR Y UN OBJETO QUE ESTE MUY CERCA DEL INTERRUPTOR.
