Machine Safety - Light Curtains

Light Curtains are one of the most common types of safety devices used in industrial and automotive sectors. A Light Curtain consists of a grid of light sources, usually LED or infrared, which act as a barrier between personnel and machines. F3SJ-A1470P55 is a particular light curtain that is designed for providing enhanced safety for personnel and machines alike. This article will discuss the application field and working principle of F3SJ-A1470P55.

Application Field

F3SJ-A1470P55 is used for a variety of applications. It is suitable for use in hazardous areas, such as metal processing, welding, and injection molding machines, as well as for use in manufacturing, packaging, transport, and warehouse applications. It is also used in robotics, amusement parks, and airports, among other places.

The main application fields for this model of light curtain are: Industrial Safety; Machine Safety; Robotic Safety; Automotive Safety; Personnel Protection; Zone Isolation; Entrance/Exit Protection; Interlocking; Guard Door Monitoring.

Working Principle

F3SJ-A1470P55 is equipped with an active infrared light curtain system that uses an array of infrared LED light sources. These light sources emit infrared light in a systematically arranged rows, which project beams of IR light that interrupts the flow of light as people or objects pass through them. If any of the light beams are blocked, the safety controller detects this and triggers an alarm or activates the safety mechanism.

The F3SJ-A1470P55 can also be used in Area guard applications as it is capable of detecting hazardous objects or conditions up to a maximum distance of 0.6 meter along the sensing axis. It can also be used in conjunction with other safety devices, such as emergency stops, gate monitors, and interlocks. It features extremely quick response time, a high dynamic range, and an adjustable sensing angle of up to 90°. The power supply is 5 VDC and the power consumption is 300mA.

F3SJ-A1470P55 is a reliable and cost-effective safety equipment that is designed to protect personnel and equipment from hazardous situations. Its application fields include industrial, machine, robotics, and automotive safety, and personnel protection. The working principle of this light curtain is based on an array of infrared LED light sources which emit beams of IR light that activate an alarm or safety mechanism when they are blocked.
