Identifying workpieces

The Lector62x image-based code reader reliably identifies the sensor type using 2D codes located on the sensor housing. The scanned information is transmitted to the control system so that the right program can be selected for performing the leak test on the sensor. The WTB4-3 photoelectric proximity sensor with background suppression reliably detects the sensor once the worker has placed it in the testing apparatus, and it then sends a digital trigger signal to the code reader.
