Light Curtains
Light curtains are vital safety devices in the industrial world. They assure the personnel and equipment working nearby that they are safe from the hazards associated with machinery and automated systems. The devices consist of two integral parts: a transmitter and a receiver. When an object passes through or blocks the infrared beams that the light curtain sends out across the sensing field that tells the machine to shut down promptly. These devices are particularly good at protecting workers in hazardous machinery areas where physical barriers might not be practical.
Light curtains, which are often used for safety in dangerous situations, are employed in many applications that allow for frequent access to hazardous areas. These includes places like assembly lines in a factory, where workers must work in close quarters to large machines and hazardous materials. Because they use light to detect when things are amiss, light curtains are great in tight spaces, where more traditional safety measures might not be practical. Some light curtains are even rugged enough to be used in places like certain assembly line stations, where the light beams might get covered in dirt and grease.
