The SD 20 Series optical level switch utilizes an infrared source and receiver. They  detect and verify the status of the infrared light reflection and penetration between the mediums in order to trigger the alarm output. The SD 20 Series benefits from the addition of a status LED so you can be certain of the level even if you cannot see inside the tank.
