A industrial machinery shutter for optical detection

The utility model provides an industrial machinery shutter for optical detection, including optical lens, front panel, rear panel, electro -magnet, photomultiplier, shutter separation blade and connecting crank, the rear panel sets up a closed shell is constituteed in the front panel rear, the electro -magnet and photomultiplier sets up the rear panel at the back, the shutter separation blade setsup the front panel with between the rear panel and pass through the connecting crank with the output shaft of electro -magnet links to each other, by adopting the above structure, the utility model,connection cooperation through electro -magnet, connecting crank and separation blade realizes that the shutter separation blade opens and shuts fast to the light that advances that into is bare the mouth is controlled to mode through the shutter separation blade opens and shuts fast, thereby realized the utility model discloses the high frequency response of shutter, and the mode through settingup hall sensor detects open
