Light curtains are safety devices that use a series of infrared beams to create an invisible barrier around machinery or hazardous areas. When an object or person interrupts these beams, the light curtain sends a signal to stop the machinery, preventing accidents and injuries. They are commonly used in industrial settings to enhance worker safety. These devices are designed to be easy to install and can be adjusted to different heights and widths, making them versatile for various applications. Light curtains are often used in conjunction with other safety measures, such as safety mats and emergency stop buttons, to provide comprehensive protection in the workplace.
