E20 DOUBLE SHEET Description: When sheets are fed automatically, two or more sheets may be fed inadvertently into a processing machine. This can damage tools, cause halt in production or result in expensive repairs. The double sheet detector E20 can reliably prevent this from occuring. In addition to the connection of one sensor an option is available to connect four sensors of the same type (E20-4P). The system can also be used for Hidden Parts Detection. The sensor switching is controlled either sequentially by the PLC or automatically in the new sequencer mode. This function eliminates the...

SINGLE SIDE SYSTEM, CONTACTING (only Fieldbus nur Feldbus) Measurement time: The table below shows the reaction time of the system when detecting Double Sheet with the maximum sheet thickness applicable to each sensor and a selected upper switching limit of 120%. The times for 2, 3 and 4 sensors apply to the sequenzer mode. Sensor Air gap behaviour: The new Double Sheet Detector E20 has a much improved air gap tolerance especially in conjunction with the new sensor P42AGS. There are two types of air gaps in case of double sheet control. First there is the air gap between sensor and sheet surface...
