42High-temperature EPC sensor HE120A (for transparent webs)The HE120A is a high temperature EPC sensor for use in temperatures of up to 300° C for detecting edges viathe transmission method. The sensor head is composed of a light-emitter and a light receiver between which themeasuring object passes for measurement. The HE120A outputs an analog signal (0 to 5 V DC), based on theamount of light blocked out by the object being measured.The HE120 high temperature EPC sensor is composed of a light-emitter / receiver unit and a heat-resistant fiber optic cable. Thelight emitted from the light-emitter (LED lamp) within the light-emitter / receiver unit passes out through the heat-resistant fiberoptic cable (for the light-emitter) and in through the heat-resistant fiber optic cable (for the light-receiver), which is located onthe side symmetrically opposite the measured object. This light is emitted onto the light-receiver element within the light-emitter/ receiver unit, converted into an electronic signal and then output as an analog signal that ranges from 0 V DC (light completelyinterrupted) to 5 V DC (light completely uninterrupted).Light-emitter/receiver unitHeat-resistantfiber optic cableOutput: 0 to 5V DC0 to 300°C 0 to 50°CComponentsHigh-temperature EPC SensorComponents1 × light trancemission/reception unit(MD0408.0-10P)2 × heat-resistant fiber optic cable(WM1003.1-12)Zero-span adjustment jig(To use this jig the fiber attachment bracketneeds to be the specified shape.)Detection range 8 mmLight transmissionand receptiondistance50 mm ±1 mmApplication(acceptablemeasuring objects)Detection of transparent web (paper,sheet steel),film (depending on the material and thickness)Mass approx. 2.3 kg(including the fiber attachment bracket)Light transmission/rececption unitModel MD0408.0-10POperating temperature range 0 to 50°C (no freezing)Operating humidity range 35 to 85% RH (no condensation)Mass Approx. 1.3 kg (includimg 5 m cable)Metal materials SPCC steel, aluminumOutput signal 0 to 5 V DCLight source Invisible light LED (870 nm)Input power +15 V DC, 130 mA?15 V DC, 60 mAStructure IP40 equivalent** Structure with the heat-resistant fiber optic cables included.Heat-resistant fiber optic cableModel MW1003.1-12Operating temperature range 0 to 300°C (no freezing)Operating humidity range 35 to 85% RH (no condensation)Mass Approx. 0.2 kg (one cable)Metal materials Stainless steelFiber optic material Muiti-component grassMinimum bend radius 50 mmStructure IP30 equivalentSensors
