Sick DeltaPac photoelectric sensor

The DeltaPac photoelectric sensor from Sick enables objects to be reliably detected in a gapless product flow.

The system uses the company’s Delta-S Technology: two energy scales each with two receivers and four PinPoint2.0 LEDs combined with Sick’s specific ASIC technology SIRIC and integrated distance measurement.

DeltaPac’s principle of operation makes use of edge contours of objects. The edges cause the reflective behaviour of the packaging surface to change in the gapless transition from one object to another. This changed direction of reflectivity is used for the output of switching signals.

According to the company, object contours with radii between 1 and 20 mm are reliably identified by the system, and its high-precision evaluation characteristic ensures that small changes in angles are reliably detected. The company claims it is possible to reliably identify up to 20,000 pieces/h with conveyor speeds of up to 3 m/s.

The system is able to detect objects aligned in a push-push configuration. Machine elements for packaging buffering and separation mechanisms are no longer required when using the DeltaPac, which can improve space utilisation.

Product flow is stabilised because collisions due to falling packaging are reduced. Machine downtime, incorrect loading when grouping items and loss of quality due to crashes can be avoided by using the system, the company claims.

The system is easy to operate. A sensor version with IO-Link is available, allowing configuration of the sensor according to application conditions.
