A new fork sensor designed by Leuze for the labeling machines used in the packaging industry combines ultrasonic and light detection technologies in a single housing. The device quickly and precisely detects a range of labels regardless of their material and surface characteristics, increases machine throughput and helps avoid downtime.
Affixing labels of various shapes, sizes and materials on products and packaging by means of a labeling 
Source: Leuzemachine is a fundamental task carried out in the packaging industry. For its precise positioning the label must be safely and reliably detected – even at high conveyor speeds. This task is performed by forked sensors, which house the transmitter and receiver in a single device and ensure high operational safety. The new fork sensor is suitable for applications where a wide range of labels need to be detected, which has typically required the use of multiple different sensors.
The GSX forked sensor can be quickly and easily set up via the teach button in order to teach the label-carrier combination. Only one universal mounting position is required for all objects and an IO-link interface serves to quickly and economically configure the sensor. The interface can be used to enable remote teaching or to lock the buttons, and recipe management facilitates easy format changeovers when replacing rolls.
