Harsh duty rectangular photoeyes have an IP69K rating for food and beverage applications and detect presence several ways: diffuse (light reflects from the target object back to the sensor), retroreflective (object interrupts light rebounding off a fixed reflector), or through-beam (object obstructs light traveling from an emitter to a receiver).
