XUV ultrasonic sensor uses thru-beam technology to detect labels of any material, size, color or translucency. It detects labels between thicknesses of 0.03 mm (0.001 in.) and 0.08 mm (0.003 in.). The detection threshold of the sensor is adjusted using the +/- keys on the sensor. Rated IP65, the sensor has an operating range of 5 ºC to 55 ºC (41 ºF to 131 ºF).
