Light Barriers, also known as Light Curtains or sometimes named photoelectric sensors and barriers or infrared sensors, are electronic devices used for safety purposes to prevent workers coming into contact with moving machines. Light Barriers work using a sensor, which, via an encoder, stops the machine from working. Prior to the invention of Light Barriers in 1952 by Erwin Sick, workplace accidents were common and often had devastating effects. The sensors used in Light Barriers work using beams of light. If these light beams detect the presence of an object in their testing field, they send a signal to the encoder to shut down the machine. The power of these electronic devices is such that they can work at a distance of up to six meters. They play an important part in ensuring the safety of fingers, hands and other body parts which may be injured should they come into contact with the moving machine. Manufacturers across many industries use these electronic devices to improve workplace safety. The sensors and their encoders can be applied to machines such as winding machines used by textile manufacturers, and also a wide range of presses. Overall, the use of Light Barriers by manufacturers is very important and helps to ensure the safety of workers. As the light barrier is suited for locations and situations, in which physical barriers would not work, these electronic devices work well for use in elevator doors and even garage doors in homes. The sensors protect a person from injury due to door closures. Furthermore, they are used by photographers, as light barriers are helpful in terms of object-, sport and animal photography.
