Heavy-Duty Type 4
Robust safety light curtains for harsh industrial environments.
Safety light curtains protect personnel from injury and machines from damage by creating a sensing screen that guards machine access points and perimeters. Banner offers intuitive, easy-to-use safety light curtains for a wide variety of safety applications.
Type 4 safety light curtains protect personnel from injury and machines from damage by guarding points of operation, access, areas and perimeters. Type 2 safety light curtains are a cost-effective light curtain safety solution for guarding lower-risk applications, where the result of an accident is only a slight injury.
Safety light curtains are electro-optical devices used to safeguard personnel in the vicinity of moving machinery with the potential for causing harm. They consist of a series of infrared light beams projected across an area. If any of the beams are broken by an object, such as a person's hand or a piece of material, the device sends a stop signal to the hazardous operation to prevent injury or damage.
Safety light curtains work by projecting invisible beams of infrared light. If an object interrupts any beam, the light curtain’s control unit detects this and sends a stop signal to halt the machine's operation. This interruption triggers a response designed to prevent injury, such as stopping a press or cutting tool.
Safety light curtains offer several advantages over traditional guarding methods, such as allowing for easier access and visibility, reduced operator fatigue, increased productivity due to less physical barriers, and enhanced safety through immediate response to potential hazards. They can also be integrated more seamlessly into automated processes.
Type 2 and Type 4 refer to the categories of safety light curtains, which are differentiated by the level of protection they offer. Type 2 safety light curtains are designed for lower-risk applications and typically protect against minor injuries, while Type 4 safety light curtains are used in higher-risk situations to safeguard against serious injury or death. Banner Engineering offers both Type 2 and Type 4 models to suit various safety requirements.
The Perimeter Guarding Type 4 Safety Light Curtains are specifically designed to safeguard the entire perimeter of a hazard zone. They differ from other safety light curtains by offering a broader protection range with one to four beams, making them ideal for larger areas where multiple entry points need to be secured.
The maximum operating range of safety light curtains is the distance over which the device can effectively detect interruptions in the light beams. This range is important to consider based on the size and layout of the area that needs protection. Banner Engineering provides options with various operating ranges to accommodate different industrial spaces.
The resolution of a safety light curtain is determined by the distance between the centers of individual adjacent beams, and refers to the size of the smallest object that can interrupt the light beams and trigger a stop signal. The finer the resolution, the greater the curtain's capability to detect smaller objects. Banner Engineering provides safety light curtains with various resolutions, including finger, hand, and body detection.
Yes, Banner Engineering’s light curtains can be integrated with other safety systems for a comprehensive safety solution. They are designed to work seamlessly with safety controllers, emergency stop buttons, and safety interlock switches, providing a complete safeguarding system.
Selecting the right Banner Engineering safety light curtain depends on the specific safety requirements of your application, including the level of risk, the type of machinery, and the size of the area needing protection. Banner offers both Type 2 and Type 4 light curtains with various resolutions and operating ranges. Please contact one of our engineers for guidance based on your application details.
