Ultrasonic Splice, Label and Double Sheet Detectors Help Detect Errors, Protect Machinery and Avoid Waste

Feb. 7, 2007
Pepperl+Fuchs introduces a new family of ultrasonic thru-beam proximity sensors for splice, label and double sheet detection. Each solution is just 18mm in diameter and features a teach-in input mode for easy set-up and operation, with a detection threshold that is easily adjusted for each specific application. They are IP67 protected and provide a sensing range from 20mm – 60mm, with an optimal sensing range of 45 mm. Splice detection systems provide a highly accurate and reliable means of detecting the presence or absence of glue, splices, bondings, or the absence of base material. Label detectors are designed for use in all applications where automatic detection of labels and carrier materials is required, including transparent or metallic labels. Double sheet detectors provide a highly accurate and low cost method of detecting zero, one or two sheets of material with weights from 10 g/m2 to 2000 g/m2. They are designed to identify mis-feeds of a wide variety of media, including paper, cardboard, thin plastic and foil. These splice, label and double sheet detectors are insensitive to printing, colors and glossy surfaces. Changes in ambient conditions are compensated for automatically, with very high processing speeds possible. • SUPPLY VOLTAGE - 18-30 VDC • LOAD CURRENT (PER OUTPUT) - ? 100 mA • VOLTAGE DROP - ? 2 VDC • CURRENT CONSUMPTION - < 80 mA • SWITCH-ON DELAY (APPROX.) - 15 ms • SWITCH-OFF DELAY (APPROX.) - 15 ms • STANDARDS - EN 60947-5-2 • Temp range(working) – +32 °F to +140 °F (0 °C to 60 °C) • Temp range(Storage) - -40 °F to +158 °F (-40 °C to 70 °C) • HOUSING MATERIAL - Nickel-Plated Brass
