The Datasensor SR21 photoelectric sensor detects labels or color marks on packaging.
The sensor has an optical feedback correction system for operation in harsh environments, and settings can be changed while machines are running. The microprocessor-controlled slot sensors have a 2-mm slot width, 12-bit resolution, and 20-μsec response time. The sensor has a special optical-feedback correction system, providing stable performance over its specified temperature range. The device can tolerate subtle vibration or movement, and detect semi-transparent labels without slowing down the line.
