The esf-1 from Microsonic is an ultrasonic label and splice sensor. It detect label reliability at high speed. The new esf-1 label sensor from microsonic is equipped with a PNP switching output and a push-pull switching output with IO-Link version 1.1. The compact fork housing can be fitted close to the dispenser edge.
Functional principle
Labels are guided through the fork, as the receiver in the upper leg of the fork receives the sound wave. The backing material transmits a different signal level from the label. The signal difference can be very slight between the backing material and the label. Moreover, it is integrated with a 3 Teach-in methods for detecting labels outside the standard.
