SF2B-A44SL

The SF2B-A44SL light curtain is a machine safety device typically used to guard personnel from hazardous machine operations. It is commonly used in production line work cells as well as in other industrial settings. The light curtain consists of photosensitive elements contained within a white plastic housing. These elements provide a invisible grid of laser beams filled within an area for personnel safety. When something breaks the beam, such as a human hand, the safety circuit in the light curtain is activated and the machine’s operation is stopped.

The SF2B-A44SL light curtain takes this idea of the classic safety light curtain and advances it to the next level. This particular device not only provides personnel safety, but can also be used to restrict access around a hazardous system. This is accomplished through the use of a caging system that completely surrounds the hazardous system, which can either be configured in a vertical or a horizontal configuration. With the SF2B-A44SL, the openings of the caging system are filled with individual optical sensors. When something breaks the beam, the caging system stops the machine operation. Automatically adjusting the transmission power and light focusing angle provide an improved safety accuracy for the caging system.

The SF2B-A44SL light curtain is designed for use in a variety of applications. It can be used to guard hazardous machinery, robotic arms, or automated systems. It is also suitable for use in hazardous areas, such as oil and gas facilities, food processing plants, paintshop applications, and dust generating operations. The SF2B-A44SL is designed for harsh environmental conditions, including temperatures from -20 to +70°C (-4 to 158°F), humidity from 10 to 95%, and pressure levels from 1.06 to 1.29MPa (153 to 186psi).

The working principle of the SF2B-A44SL light curtain is based on a infrared beam grid. This beam grid is generated by an array of emitters and receivers mounted in the white plastic housing. The emitters and receivers are connected to an electronic circuit board, which is responsible for generating and managing the light signals. When something breaks the beam, a signal is sent back to the central control system. This signal triggers the safety circuit and automatically stops the machine. The sensitivity of the light curtain can be adjusted as needed, ensuring accuracy and reliability.

In conclusion, the SF2B-A44SL is an advanced machine safety device that provides both personnel protection and restricted access in hazardous systems. Its infrared beam grid technology ensures high-precision accuracy and reliability, while its caging system allows for quick and easy installation. The SF2B-A44SL is suitable for a variety of industrial and hazardous applications due to its ability to withstand harsh environmental conditions. With its easy installation and advanced safety features, the SF2B-A44SL light curtain is an ideal choice for safeguarding personnel and machinery.
