1.1 System Overview
SCAN light curtains consist of a transmitter and a receiver. Like a light barrier, they
work with modulated infrared light and stand out due to the following features:
• Measurement field up to 6 m wide, from 900 to 3000 mm high
• 30 mm resolution at every position of the measurement field
• Can be connected directly to an PLC control (such as the Siemens S7-200)
• PNP switch output for measurement field status free/occupied
• Simple connection due to M12 connector
• Contamination and error signal output to the PLC
• Extremely small design (cross-section 17 mm x 33 mm)
