Light curtain safety devices are designed to prevent personnel from entering a hazardous area of a machine during operation. SF4B-H72C is a light curtain product that is commonly used in applications such as machine tools, automotive assembly lines, and material handling systems. In this article, we will discuss the application field and working principle of SF4B-H72C.

Application Field

SF4B-H72C is an adjustable, non-contact light curtain that is designed for use in areas where personnel may come into contact with hazardous machinery during operation. The light curtain is designed to prevent personnel from entering the hazardous area of a machine when the machine is in operation. It can be used in a variety of applications such as machine tools, automotive assembly lines, and material handling systems.

SF4B-H72C is a safe, efficient, and reliable way to ensure personnel safety in hazardous areas. The light curtain can be adjusted to fit any size of hazardous area. It has a range of up to 3000mm and is available in lengths ranging from 800mm to 5000mm. It is also IP67 rated, meaning it is resistant to dust and water ingress.

The SF4B-H72C is also designed to be resistant to EMI and RFI interference, which is common in industrial environments. The light curtain is also certified for CE, UL, and other safety standards.

Working Principle

The SF4B-H72C operates on a two-step process. The first step is the emitter, which emits an invisible IR light beam. This light beam is detected by the receiver. When the light beam is broken by an object, the receiver will send a signal to the safety unit, which will then activate the safety function of the machine.

The safety unit is the controller that is responsible for activating the safety function of the machine. It is programmed to react to a break in the light beam. When the light beam is broken, the safety unit will activate the safety function of the machine, which can include stopping the machine, preventing it from starting, or activating a warning light or signal.

The SF4B-H72C is also equipped with a self-checking feature, which helps ensure that the light curtain is working properly. If there is a break in the light beam or if there is a power outage, the safety unit will activate a warning light or signal and prevent the machine from operating.

The SF4B-H72C is designed to provide personnel safety in hazardous areas. It is easy to install and adjust, and it is certified for a variety of safety standards. The light curtain is resistant to EMI and RFI interference, and it has a range of up to 3000mm. It is a safe, efficient, and reliable way to ensure personnel safety in hazardous areas.
