Abstract
An infrared light sensor outside the milk flow path is connected with an end of milking indicator. The light sensor is connected with a milk flow detector which actuates the indicator giving a visual or audible signal when milk flow ceases. Vacuum is shut off and the milker is retracted. Electrical power for the light source, light sensor and indicator circuit is derived from the milker pulsator signals.
