For double layer detection of other thin metal layers please contact Roland Electronic GmbH in Keltern / Germany. LED Power green: Power is supplied Connector M8 Power / Signal Pin 1 → +24VDC supply voltage Pin 2 → Current output (4 - 20mA) Pin 3 → GND Pin 4 → Voltage output (2 – 10V) → brown → white → blue → black Important notes: Sensor WF14x15AQ453S is especially designed for the Schmalz Wafer Gripper SWG. This type of Gripper is ideal for the task of double cell detection. The following requirements are fulfilled: 1. No conductive material in the surrounding area of the sensors tube...

Voltage output vs number of cells (air gap 0.5mm) 10 cell type A [V] cell type B [V] cell type C [V] cell type D [V] cell type E [V] Note: cell type doesn’t mean a standardized classification. Cell type classifies the influence of thickness of silicon, back-surface field and busbars. This influence will cause different levels of output voltage. Important: Considering that the sensor output voltage depends on cell type a Teach-In Procedure for reliable measuring is essential. Voltage output vs air gap (Cell type B) 10
