Abstract
A sensor device includes a sensor to detect a light beam to measure states of work pieces or a distance to the work pieces, a case body housing the sensor, and a protective cover including a protective plate that transmits the detection light beam. The protective cover includes a gas flow channel that passes a gas to be blown to the protective plate, the gas flow channel having formed therein an outlet port that passes the detection light beam and discharges the gas having flowed through the gas flow channel. The gas flow channel includes an accumulator between the protective cover and the case body adapted to have accumulated therein the gas flowing through the gas flow channel, and the accumulator includes vent holes through which the gas is allowed to flow out toward the outlet port.
