Caretaker Ultra Flex 2 8-Port Sensor Assembly (Gray)
The Gray Sensor Assembly is used on UltraFlex 2 Cleaning Systems using the Sensor Plate with square holes. If your Sensor Plate uses bent tabs then you will need the Black Sensor Assembly.
The Sensor Assembly is designed to read the tab passing through it. Once the tab passes through, the sensor communicates with the PCB on the Motor and tells it to stop for the selected duration of time. Once the pop ups have cleaned for the desired amount of time, the motor rotates again until the next tab passes through the optic isolator. The sensor is dependent on light, if the Lid Assembly is not on securely the unit will not operate at all.
