Panel Detector for PCB
Double panel detectors
for copper laminated panels (PCBs) are designed for detecting double or multiple panels on
automated de- stacking units and transfers. The detector consists of a pair of sensors and
an amplifier. The panel to be checked is passed through the gap between both sensors
Single panel passes through the sensorīs gap and do not activate the relay of amplifier.
If two or more panels passes through the sensorīs gap the relay is activated. The output
change over contact (SPDT) can be used to switch off the panel conveyor and/or for
activating optical / acoustical alarms.There is also an amplifier available that has an
analog voltage output of 0- 10 VDC instead of the output contact. This voltage co- relate
to the copper laminate thickness of the PCB. This amplifier can be used in connection with
a PLC/ IPC/ controller that has an analog voltage input for example for min./max limit
monitoring, remote control monitoring, "teach- in" programming with a
sample PCB etc.

New ! (Fig 1) "All in one" double sheet sensors
with analog- or digital- output. No additional amplifiers / controllers are necessary.
These sensors contains all parts, connector, indicator LED etc. and are therefore low
prices units. The analog sensors have 1 - 10 VDC outputs. The digtal sensors have 2 switch
outputs: One for 0/1 panel and one for 1/2 panels. The sensor is teach-in
Cu-layerthickness programmable with a reference panel. It also can be used for to
discriminate / monitor panels in the 18, 35, 70, 140...mym ( 1/2 , 1 , 2 , 3 ...
oz/sq.ft ) Cu- layerthickness steps.
