The BWF-11B is a high-performance optical data receiver engineered for industrial automation, designed to pair seamlessly with HOKUYO’s BWF-11A transmitter. Leveraging infrared FSK (Frequency Shift Keying) modulation at 950nm , it ensures reliable long-range data transmission up to 100 meters with ±2° directional accuracy . Its wide-angle reception (50° vertical / 90° horizontal) eliminates the need for precise alignment, making it ideal for dynamic environments like automated storage systems (AS/RS) and overhead cranes . The receiver incorporates advanced noise-filtering circuitry to mitigate interference from ambient light (up to 10,000 lux) and electromagnetic noise, ensuring stable communication in high-noise settings such as automotive assembly lines . A built-in signal strength monitoring system provides real-time feedback via LED indicators, alerting operators to potential misalignment or lens contamination .
Encased in an IP65-rated ABS resin housing , the BWF-11B withstands dust, water splashes, and extreme temperatures ranging from -10°C to +50°C. This robust design ensures operational resilience in outdoor logistics hubs, steel mills, and other harsh industrial settings. The unit’s dual-axis alignment mechanism simplifies optical axis calibration using a transceiver-assisted process, reducing installation time by 30% compared to traditional methods . Its UV-resistant coating protects against long-term degradation from sunlight exposure, while the compact form factor (170mm x 60mm x 30mm) and lightweight (500g) design enable easy integration into space-constrained machinery . Compliance with CE certification and RoHS directives ensures global regulatory compatibility .
The BWF-11B supports multiple industrial interfaces, including RS-232C, RS-422, and 20mA current loop, allowing seamless integration with PLCs, robotic controllers, and AGVs . Its semi-E84 standard protocol ensures interoperability with HOKUYO’s BWF-11A transmitter and third-party devices, facilitating scalable automation systems. With a fast response time (<10 ms) and data rate of up to 19.2 kbps, the receiver enables real-time coordination in material handling applications, such as conveyor belt systems and automated guided vehicles . The 2m pre-wired M12 connector cable enhances connectivity reliability, while the isolated outputs protect against voltage spikes . Widely adopted in logistics, manufacturing, and semiconductor industries, the BWF-11B exemplifies HOKUYO’s commitment to precision-engineered, future-proof automation solutions.
