Product Specification

High-Speed Optical Data Transmission System for Semiconductor AMHS

The HOKUYO EWF-11B is a cutting-edge optical communication module engineered for mission-critical applications in semiconductor automated material handling systems (AMHS) and AGV/AMR navigation. Built to SEMI E84-0200A compliance , this device enables seamless interlock sequence communication between 300mm wafer handling equipment and overhead hoists (OHTs), ensuring real-time data exchange with ±2° optical alignment tolerance . Leveraging FSK modulation (5.5/6.0 MHz dual-frequency operation) and RS-422 interface, the EWF-11B achieves 19.2 kbps transmission speed with 100-meter line-of-sight range, outperforming Sick’s ODSU-2000 (80 ms cycle time, 150 m range) in both speed and distance. Its dual-mode operation (master/slave) ensures reliable link management in industrial open networks, while the 25-pin D-sub connector aligns with SEMI E84 pin assignments for plug-and-play integration in semiconductor fabs. The IP40-rated polycarbonate housing resists dust and light splashes, making it suitable for ISO 14644-1 Class 5 cleanrooms.

Ruggedized Design for Harsh Industrial Environments

Designed to withstand extreme operational demands, the EWF-11B features 490 m/s² shock resistance (IEC 60068-2-27) and 1.5 mm vibration tolerance (10–55 Hz) , ensuring stable performance in high-shock environments like railway shunting systems and automotive assembly lines. Its -10°C to +50°C temperature range and 85% RH humidity tolerance surpass standard industrial requirements, while the halogen/mercury lamp-resistant design (20,000 lux) minimizes interference from high-illumination factory settings. Unlike Keyence’s GLV series, which lacks robust environmental protection, the EWF-11B’s ferroelectric memory logs up to 100 data change events for traceability and diagnostics. The DC 24V ±10% power supply and 80 mA power consumption optimize energy efficiency for 24/7 operations, supported by a 5-year warranty and global technical support.

Smart Integration for Industry 4.0 Ecosystems

The EWF-11B redefines automation flexibility with multi-protocol compatibility for PLCs, HMIs, and robotics platforms like Fanuc and ABB. Its onboard potentiometer configuration allows quick adjustment of transmission zones, reducing setup time by 30% compared to traditional wired solutions. The SEMI E84 protocol alignment streamlines communication in semiconductor fabs, while the RS-422 interface supports daisy-chaining up to 32 devices for large-scale deployments. For vertical lift modules (VLMs) and pharmaceutical logistics, the ROS (Robot Operating System) compatibility enables seamless integration into autonomous robotics networks, providing real-time data for navigation and collision avoidance. With EMC immunity (IEC 61000-4-3) and CE/UL certifications , the EWF-11B delivers reliable, protocol-compliant connectivity for smart factories. Whether deployed in high-speed wafer transfer or precision material handling, this module combines precision, durability, and adaptability to meet the evolving demands of Industry 4.0.
