This detection collection includes photoelectric, leak and level-sensing listings. A photoelectric device detects a target using light; a leak sensor responds to liquid at its sensing location. They solve different problems and should not be selected by housing size alone.
For tank-level control, go to level sensors. For short-range machine detection, compare proximity sensors with the sensor type already installed.
