In the present invention, disclosed is a limit sensor of a feeder for domestic animal feed, comprising a housing whose upper end is connected to a feed discharging pipe and lower end is opened to supply feed; an installation space which is formed by which the inside of the housing is partly protruded outside; a limit switch installed in the installation space; and a sensing box, which is inserted in the installation space and accordingly connected and has an opening hole on one side in an insertion direction to prevent overlap in the limit switch, when being inserted, and whose front surface toward the inner space in the housing is made from a fluid film moving to lower part pressurized by feed, thereby separating the installation space from the inside of the housing while covering the position of the limit switch. |
