The device is a ultrasonic sensor for detecting the presence of labels. The technology allows detection of a wide range of labels: low contrast, transparent, metallized, hot stamping and others. It is precisely such a sensor used in our semi-automatic STS808 machine
The electrical connection allows selection of the PNP or NPN type and selection of the output function (NO / NC). The active state of the output is indicated by the ‘O’ LED and eventual overloading by the ‘S’ LED.
The presence of bargraph for the signal level and the function keys facilitate setup.
