The Pantron electro-optical system is ideal for flushing areas, car washes and amusement park water rides because they are IP67 protected and 100% submersible. Pantron photoelectric eyes are available in hardwired and quick-disconnect versions. Hard-wired photoelectric eyes are fitted with color-coded strain relief devices at the points where the cable is connected to the body. This reduces the stress applied to the connection between the wire and the photoelectric eye and provides a way to easily identify the transmitter (red) and receiver (black).
