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.
