Abstract
Изобретение относитс к электротехнике , в частности к бесконтактным выключател м , и может быть использовано в качестве датчика угла поворота. Цель изобретени - расширение функциональных возможностей . Бесконтактный выключатель содержит корпус 1, вал 5, экран 8, оптопары с источниками 9 света и фото датчиками 10. Вал с экраном выполнены так, что их центр масс смещен относительно оси вала. Полость 3 корпуса заполнена светопроницаемой жидкостью . При повороте корпуса вал с экраном остаютс неподвижными и экран поочередно перекрывает световой поток в одной из оптопар. 1 з.п.ф-лы, 2 ил.The invention relates to electrical engineering, in particular to proximity switches, and can be used as an angle sensor. The purpose of the invention is to expand the functionality. The proximity switch includes a housing 1, a shaft 5, a screen 8, optocouplers with sources 9 of light and a photo sensor 10. The shaft with a screen is made so that their center of mass is offset from the axis of the shaft. The cavity 3 of the housing is filled with a transparent liquid. When the housing is rotated, the shaft with the screen remains stationary and the screen alternately blocks the luminous flux in one of the optocouplers. 1 hp ff, 2 ill.
