They can detect the edge of a web with high accuracy. They arenot affected by irregularities in the coating near the edge of transparent film and printed patterns, which affectsoptical sensors. Combined with Nireco’s controller, an electrical EPC system or electrohydraulic EPC system can beconstructed. The UH01A is a version of our UH01 ultrasonic sensor with a longer internal length (the distance fromthe sensor center position to the inner side of the casing). Internal lengths of 200 mm, 300 mm, 400 mm and 500mm are available. The internal length of the UH01 is 60 mm (fixed).Model UH01 UH01A UH01S *4 UH01SA *4Sensor gap 48 mmEffective detectionlength 8 mmSensitivity Detects a web displacement of 0.1 mmFrequency response 200 HzSensor outputHi mode *1When fully closed 0 V DC, When fully opened +5 V DCLo modeWhen fully closed 0 mV DC, When fully opened +300 mV DCResistance load of at least 2 kΩWhen fully closed 0 V DC, When fully opened +300 mV DCPower supply +15 V DC (100 mA) ,?15 V DC (50 mA) +7 ~ +12 V DC (70 mA)Ambienttemperature 0 to +50?CAmbient humidity 35 to 85%RH (no condensation)Mass: Cable (5 m) 0.36 kg 0.1 kg/m Approx.Screw guider *3 0.63 kg *2
