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).
In the latter configuration the system is also 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 switching of the measuring
channel or the program by the PLC. A measurement of 4 separate sheets of 1.0 mm thickness with the P42AGS sensor and a 120%
double sheet threshold takes less than 305 ms by using the sequencer. In contrast the same measurement with program switching
by the PLC takes more than 700 ms.
Function:
The double sheet detector is based on the electromagnetic principle. It monitors ferromagnetic sheets with single sided sensors and
exerts forces during the monitoring process only. A change of the sheet thickness results in a change of induction. The system
calculates the sheet thickness from this change. Corresponding to the pre-set limits 0-sheet, 1-sheet or 2-sheets signals are
generated.

DOUBLE SHEET DETECTOR E20
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.
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 1st air gap with sensor P42AGS: According to the diagram, if processing a sheet of 2.0 mm (.08 in.) an air gap of 0.5
mm (.02 in.) can be tolerated with a double sheet threshold of 120 %.
Example for 2nd air gap and sensor P42AGS with 2.0 mm (.08 in.) sheet thickness and a double sheet threshold of 120 %; an air
gap of up to 3.0 mm (.12 in.) can be tolerated.
Attention ! The performance data of both diagrams cannot be combined !
Measurement time:
