F80

50Hz High-Frequency Obstacle-Avoidance Laser Scanner—The Top Choice for Safety in Semiconductor OHT Cranes and High-Speed AGVs

The F80 is an industrial-grade LiDAR sensor designed specifically for high-speed mobile devices. It breaks through the frequency limitations of conventional radar, offering a scanning frequency of up to 50 Hz—meaning it can perform 50 full-range scans per second, representing a quantum leap in response speed. Combined with its ultra-compact dimensions of 50 mm × 50 mm × 70 mm, the F80 can be seamlessly integrated into high-speed equipment such as semiconductor OHT cranes and shuttle cars—devices that are highly sensitive to space and weight constraints.
The F80 boasts a reliable detection range of 8 meters (10% reflectivity) and features 32-zone group switching functionality. Specifically designed for semiconductor cleanroom environments, it optimizes its recognition algorithms to effectively detect black, light-absorbing materials as well as highly reflective objects, and it offers an impressive resistance to light interference up to 80,000 lux. The F80 serves as a domestically produced alternative to high-end imported radars, making it an ideal solution for ensuring the safe handling of wafers and high-speed logistics operations.

Overview

50Hz Ultrafast Response

A conventional radar scan takes 66 ms, whereas the F80 requires only 20ms When the OHT overhead crane is operating at a high speed of 3–5 m/s, a shorter data refresh cycle means a shorter braking distance and enhanced safety.

Ultra-compact body

50×50×70mm Its dimensions are completely consistent with those of imported competing products. It can be easily integrated into the confined spaces of overhead cranes without occupying valuable track resources, enabling seamless replacement and upgrades.

Semiconductor Scene Optimization

Built-in dedicated algorithms tailored for common scenarios in cleanrooms. High-reflective metal 、 Black light-absorbing material And Transparent glass Optimized to effectively block environmental interference and ensure that alarms are triggered only by genuine obstacles.

The Eye of the Sky Crane

Semiconductor Overhead Crane Application

In the wafer fab’s overhead environment, OHT cranes swiftly shuttle back and forth, carrying priceless wafer cassettes. The ILS-F80 acts like a pair of keen eyes, installed around the crane to create a 270° virtual light curtain. Whether it’s foreign objects on the track ahead or robotic arms extending from the side, the F80 can detect them within milliseconds and trigger either deceleration or an emergency stop, ensuring zero-accident operation of the production logistics.

Why is the F80 a specialist in high-speed obstacle avoidance?

50Hz refresh rate, safer braking distance

On a crane traveling at 5 m/s, every millisecond of delay translates into a loss of several centimeters in braking distance. The F80 increases the scanning frequency to... 50Hz The data refresh cycle is only 20 ms.

This means that under the same emergency conditions, the F80 can detect obstacles about 46 milliseconds earlier than a conventional radar (15 Hz), giving the control system valuable reaction time, thereby shortening the braking distance and helping to avoid collisions.

32 regional groups, compatible with complex track logic

The OHT’s operating trajectory includes various conditions such as straight-line travel, sharp turns with large curvature, and junctions. The F80 supports up to 32 groups Dynamic switching of regional groups (each group contains 3 sub-regions).

Using five input signals, the host computer can precisely select the corresponding protective pattern based on the track position, perfectly matching the vehicle body and track contours. This approach not only prevents false alarms during turns but also ensures long-range detection when driving straight.

8 meters @ 10%, stable detection of black objects

The F80 employs Time-of-Flight (TOF) technology combined with multi-echo processing, delivering an exceptional signal-to-noise ratio. Even when encountering black objects with a reflectance as low as 10%, it can still... 8 meters Stably detected within the range.

Its measurement accuracy reaches ±3 cm Moreover, its high consistency and repeatable precision ensure the accuracy of obstacle-avoidance signals, preventing the vehicle from unexpectedly coming to an abrupt stop due to data fluctuations.

Type-C convenient debugging, compact and easy to install.

The F80 is equipped with a universal... Type-C With the debugging interface, engineers can quickly connect to a computer for area mapping and parameter configuration without needing to carry bulky, dedicated cables. It also supports RS232 communication, making it easy to interact with controllers.

With its compact 50×50×70mm dimensions, the design fully takes into account the space constraints within the overhead crane, where every inch counts. The mounting bracket is designed to be flexible, allowing for quick deployment across different vehicle models.

Anti-collision and Precise Positioning for AMHS Overhead Cranes in High-Speed Operation

In the wafer fab cleanroom—where every inch of space is precious—AMHS system OHT cranes must operate densely at speeds of up to 3–5 meters per second along a complex network of overhead tracks, efficiently handling the flow of wafer cassettes (FOUPs). Should a collision or drop occur, not only would expensive wafers be damaged, but the entire production line could come to a standstill, resulting in immeasurable losses. Traditional obstacle-detection sensors often either are too bulky to be easily integrated into the compact crane body, or have low scanning frequencies that lead to delayed responses at high speeds. Moreover, these sensors struggle to accurately detect black or highly reflective foreign objects on the tracks, posing significant safety risks.
