Detection of solar wafers in harsh wafer production environments

Before further processing, the wafers are cleaned of the residues of the wire saw procedure in an abrasive wet process. The sensors used here are constantly exposed to chemicals. These can attack the front screen or the complete housing. The W4S-3 Inox photoelectric sensor is resistant to this. With the optional IO-Link interface, the reading window of the sensor can be continuously monitored, which reduces machine downtimes.
