Light curtains are automated devices used to detect entry into hazardous areas. In the industry, light curtains are placed where hazardous area access is required, such as between the work area and machine area. The SF4B-A36-01(V2) light curtain (or Electrical Interlock Shield) is designed to provide a secure safety interlock for personnel access control and machine safety.

SF4B-A36-01(V2) Application Field

The SF4B-A36-01(V2) light curtain is made of a highly sensitive lens, processor, and emitter. It\'s used in a variety of applications including automated machines, industrial machine, robots, pick-and-place machines, tool changers, and machine tools. SF4B-A36-01(V2) provides a safe and reliable protection of personnel against accidental and potentially hazardous occurrences.

SF4B-A36-01(V2) Working Principle

The SF4B-A36-01(V2) uses a highly sensitive lens, processor, and emitter to detect entry into hazardous areas. The emitter sends out an infrared beam that travels to the receiver forming an invisible light curtain. When a person or object interrupts the beam, the receiver senses a change in the beam and sends a signal to the processor. The processor then sends a signal to the machine to stop automatically.

The SF4B-A36-01(V2) provides two levels of safety. The first level of safety, when alerted, the processor sends a signal to stop the machine before entry is made into the hazardous area. The second level of safety stops the machine upon full entry into the hazardous area by sensing the position of the person or object that entered.

The SF4B-A36-01(V2) also features adjustable sensitivity to intensity, delay time, and positioning time. This allows the user to customize the SF4B-A36-01(V2) to fit the machine needs. Additionally, the SF4B-A36-01(V2) is IP66 rated, providing protection against dust, water, and other external factors.

Conclusion

The SF4B-A36-01(V2) light curtain is an ideal machine safety solution for machines that require personnel access control or protection from hazardous areas. By using the highly sensitive lens, processor, and emitter, the SF4B-A36-01(V2) provides two levels of safety and adjustable sensitivity settings. This makes the SF4B-A36-01(V2) a reliable and well-designed machine safety light curtain.
