A light curtain is an electrical safety device that utilizes a series of light beams to create an invisible barrier around a machine or hazardous area. When an object, such as a person's body, interrupts the light beams, the system detects this interruption and triggers a safety response, typically stopping the machinery to prevent injury. This technology is particularly useful in environments where physical barriers are impractical or would inhibit operational efficiency.

Light curtains serve as a crucial component of machine guarding, enhancing safety by providing a non-contact means of protection for workers around moving equipment. They are designed to be compliant with safety standards, ensuring that they function effectively to protect personnel while allowing for safe machine operation when protected zones are clear. This innovative approach to safety supports dynamic workflows while maintaining high levels of protection.
