Walk into many manufacturing facilities today, and you'll likely spot an invisible barrier of infrared beams guarding a press, robotic arm, or conveyor line. A light curtain sensor creates this protective field between a transmitter and receiver—when something breaks it, the system detects the interruption and can signal nearby machinery to respond. Unlike physical guards, light curtains don't block workflow, making them a common choice around press brakes, robotic work cells, conveyor lines, and assembly stations where humans and machines work close together. They're typically used alongside other safety measures like emergency stops and interlocks, and performance can depend on proper installation and environmental factors, so it's worth evaluating suitability for your specific setup.
