Light curtains use a non-visible screen of infrared light to protect personnel from injury and machines from damage by guarding points of operation, access areas and perimeters. The interruption of a single light beam will signal an emergency stop for a machine in operation.
Light curtains are installed on potentially dangerous machines, robots and other automated systems where it is possible to access a dangerous area. Light curtains are found on automated machines such as on large hydraulic presses or welding robots where personnel could potentially interfere with the machines moving parts. Light curtains are also used to protect personnel from accessing dangerous electrical circuitry on assembly lines.
Light curtains are sold in pairs that include a transmitter and receiver. The transmitter emits the infrared light beams and the receiver consists of a certain number of photoelectric sensors for each light beam emitted. When an object disturbs one of these light beams, a signal is sent to stop the machine.
Light curtains are usually paired with safety relays which control certain parameters such as, signal strength for long range or short range detection.
In order to have the light curtain function properly on your machine or automated assembly line, make sure to specify the level of protection. There are two types of light curtains; Type 2 and Type 4. Type 2 being lower cost with fewer features compared to Type 4 which has a higher resolutions and scanning range. Make sure to specify your safety requirements and the application you would like to have your light curtain installed.
