F20-B

Industrial-grade safety laser scanner—high-performance, cost-effective import alternative, the top choice for the textile and synthetic fiber industry.

The F20 is a high-performance 2D laser scanning sensor specifically designed for industrial area protection. Based on Time-of-Flight (TOF) ranging technology, it offers a 270° field of view and an exceptionally wide detection range of 8 meters (at 2% reflectivity). The F20 was developed specifically to replace expensive imported equipment, enabling equivalent safety protection logic at a lower cost in scenarios where mandatory safety certification is not required.
The F20 features a built-in dual-circuit safety output (OSSD) with external device monitoring (EDM) functionality and supports switching among 16 zone groups. Its filtering algorithm has been specially optimized for the textile and synthetic fiber industries, enabling it to effectively penetrate flying fibers and dust particles, thereby addressing the high false-alarm rate typical of conventional photoelectric switches. With an IP67 protection rating and outstanding shock resistance, the F20 is the ideal safety guardian for applications such as bobbin-reeling machines, stackers, and automated production lines, helping to reduce costs and improve efficiency.

Safety Applications in Textile Workshops

The F20 is playing a critical role in applications such as bobbin-retrieval carts at synthetic fiber plants, automated guided vehicles in spinning mills, and stacker cranes in automated warehouses. Replacing traditional mechanical bumpers, the F20 provides non-contact safety protection. Thanks to its flexible zone-setting capability, the F20 not only prevents vehicle collisions with personnel but also avoids frequent downtime caused by misidentifying environmental features—such as walls or pillars.

Advantages: Feature alignment, powerful performance

8-meter ultra-large protection radius—surpassing the competition.

Typical safety radar protection distances are only 3–5 meters, whereas the F20 increases this figure to... 8 meters (For objects with a low reflectance of 2%).

This means that the F20 can cover a wider hazardous area, or allow mobile devices to operate at higher speeds (because there’s sufficient braking warning distance). In conjunction with... 270° With its wide field of view, a single device can achieve full coverage of the equipment’s corners or sides, eliminating blind spots.

“Anti-Interference Brain” Optimized for Dusty Environments

In industries such as textiles, woodworking, and flour milling, airborne fibers and dust are the “archenemies” of optical sensors. Rather than simply transplanting general-purpose algorithms, the F20 was specifically developed with targeted approaches. Dust Penetration and Filtration Model 。

It can intelligently detect and ignore tiny floating particles, responding only to actual people or obstacles. This significantly reduces the number of false shutdowns on the production line, enhancing production efficiency while ensuring safety.

Graphical configuration—easy to use right out of the box.

The F20 is equipped with an intuitive Chinese host computer software. Users can simply drag and drop with the mouse to draw protection zones (in red) and alarm zones (in yellow) of any desired shape.

Supports 16-zone configuration, allowing real-time switching via external I/O signals. Whether it’s AGV turning and obstacle avoidance or protective switching between different workstations for robotic arms, all can be easily achieved.

IP67-rated protection—no fear of harsh operating conditions.

The F20 features a fully sealed metal body design with a protection rating that reaches... IP67 Completely prevents dust from entering and can withstand brief immersion.

After undergoing rigorous vibration and shock tests (GB/T 2423), the F20 can withstand the continuous vibrations generated by long-term operation of trolley cars and AGVs, ensuring stable performance over the long term and reducing maintenance frequency.

Anti-collision protection for Overhead Hoist Transporters (OHTs) in the synthetic fiber workshop

In modern fiber-fabrication plants, automated material handling systems (AMHS) are becoming increasingly widespread. Often, multiple Overhead Hoist Transporters (OHTs) need to operate at high density and high speed on the same single-track system. Due to the heavy loads carried by these vehicles—each fully loaded with silk cakes—and their substantial inertia, coupled with the fact that the tracks typically run above equipment, a rear-end collision or an impact with obstacles such as track maintenance ladders could not only pose a serious risk of objects falling from height but also bring the entire logistics line to a standstill. Traditional contact-type anti-collision barriers can only take effect once a collision has already occurred; they cannot maintain a safe distance in a non-contact manner.

Safety Protection for Mobile Operations of Synthetic Fiber Winding Machines

In the synthetic fiber textile workshop, automatic bobbin-replacement carts need to frequently shuttle back and forth between the long winding machine aisles, performing the heavy-duty task of changing bobbins. The aisles are narrow, and often populated by inspectors or temporarily parked trolleys. Once a bobbin-replacement cart collides with personnel while moving, it not only could cause injuries to workers but also might damage the precision winding machines—and even bring down the entire production line, resulting in substantial losses. Traditional mechanical anti-collision strips are slow to react and cannot provide non-contact, proactive safety protection.

Safety Protection for the Swing-Arm Working Area of CNC Pipe Bending Machines

When using a CNC pipe bending machine to process long pipe components, as the bending die rotates, the tail end of the pipe undergoes significant lateral swinging—commonly referred to as "tail sweeping." This process is fast-paced, involves high torque, and the hazardous area varies depending on the length of the pipe component. Traditional physical barriers not only occupy substantial workshop space but also severely impede the frequent loading and unloading of long pipe components and the replacement of dies, thereby reducing production efficiency. Therefore, a key requirement for upgrading safety in pipe-bending workshops is how to effectively prevent operators from being struck or squeezed by swinging pipe components without resorting to physical barriers.

Automatic bobbin-releasing machine for synthetic fiber lanes—collision protection during operation

In the synthetic fiber textile workshop, automatic bobbin-releasing machines need to move back and forth within narrow, elongated machine aisles. Due to the enclosed and confined nature of these aisles, if an operator accidentally enters the aisle for inspection or cleaning, they could easily be squeezed or struck by the high-speed bobbin-releasing machines. Moreover, since the bobbin-releasing machines are equipped with lifting mechanisms, a collision could not only cause personal injury but also result in the costly silk bobbins being dropped and damaged while being handled. Ensuring the safety logic of "machines stop when people are present, and people stop when machines are operating" in such a cramped, human-machine-shared space is a major challenge in production management.
