E20 Double Sheet Detection for steel sheets with contacting sensors - 2

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 time-consuming...

E20 Double Sheet Detection for steel sheets with contacting sensors - 3

Sensors: It is recommended to use the sensors P30GS, P42AGS and P75VGS with the control unit E20. The connection of the older P36GS, P42GS and P75GS sensors is also possible. (only Fieldbus) Air gap behavior: 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 (1st air gap) and the air gap between the first sheet and the second sheet (2nd air gap). The diagrams show the relationship. Example for...
