High-Speed Serial Optical Data Transmitter for Industrial Automation
The HOKUYO BWF-11A is a high-performance serial optical data transmitter engineered for seamless wireless communication in industrial automation systems. Operating at a transmission speed of up to 19.2 kbps , this compact device uses infrared (950 nm) FSK modulation to ensure reliable data transfer over distances of up to 50 meters . Its rugged ABS resin housing with IP65-rated protection withstands dust, water splashes, and extreme temperatures (-10°C to +50°C), making it ideal for harsh environments like automotive assembly lines, semiconductor cleanrooms, and logistics hubs. The BWF-11A supports multiple interface options, including RS-232C, RS-422, and current loop , enabling flexible integration with PLCs, robotic controllers, and AGVs. Unlike traditional RF-based systems, its infrared transmission avoids electromagnetic interference and regulatory restrictions, ensuring stable operation in high-noise settings .
Long-Range Wireless Coordination for Automated Material Handling
Designed for mission-critical applications, the BWF-11A excels in long-range communication for overhead cranes, stacker systems, and automated storage and retrieval (AS/RS) systems. Its wide optical reception angle (50° vertical / 90° horizontal) allows flexible installation without precise alignment, while the built-in noise-filtering circuitry minimizes signal degradation from ambient light (up to 10,000 lux) . The transmitter’s modular design supports semi E84-standard communication protocols , ensuring compatibility with HOKUYO’s BWF-11B receiver and other industrial devices. With a quick-response time of under 10 ms, it facilitates real-time coordination between moving vehicles and stationary control units, reducing downtime in logistics and manufacturing. Compared to competitors like Keyence’s SR-1000 or Sick’s ODS60, the BWF-11A offers superior resistance to mechanical wear and requires no recalibration over its operational lifespan .
User-Friendly Design for Easy Integration and Maintenance
The BWF-11A prioritizes ease of use with plug-and-play connectivity and intuitive optical axis adjustment. Its 2m pre-wired M12 connector cable simplifies installation, while the dual-axis alignment mechanism allows precise positioning using a transceiver-assisted calibration process . The unit’s status LEDs provide real-time feedback on signal strength, power status, and data transmission, streamlining troubleshooting. With low power consumption (≤3W during operation) , it enhances energy efficiency in multi-device networks. The BWF-11A is CE-certified and RoHS-compliant , ensuring compliance with global safety and environmental standards. Whether used in CNC machining centers or packaging lines, this transmitter empowers industries to achieve seamless, high-speed data transfer while maintaining robust performance in demanding industrial environments.
