Eltrotec's FA 98 Ultra ultrasonic fork-frame light barrier can detect transparent labels printed with metal particle lacquers on transparent backing films. The FA 98 Ultra works at a precision rate of 100 per cent when triggering labelling machines.With its rim width of 3mm and a fork depth of 70mm, it can be applied for various labels and, due to its depth, even reaches significant trigger points located further on the inside of a carrier material. High repeatability is ensured with a switching frequency of 1KHz and the simple adjustment of rims and gaps via teach-in. Because of the ultrasonic principle, extraneous light does not affect the sensor.
