YH-G9540 RFID Industrial Reader
The YH-G9540 industrial UHF RFID reader is tailored for automated production line integration. Featuring ultra-compact size, DC 9-36V wide voltage input and native Modbus RTU protocol, it supports on-site antenna calibration to avoid tag cross-reading. Compatible with nearly all mainstream PLC devices, it enables fast and cost-effective RFID deployment for narrow industrial workstations.
The YH-G9540 industrial UHF RFID reader is built to tackle practical deployment dilemmas on factory production lines. Different from oversized standard RFID readers that require customized mounting brackets, its miniaturized structure allows seamless installation in cramped workstation gaps, robotic fixture interiors and narrow conveyor side rails with no mechanical structural modification required — a pain point repeatedly mentioned by automation system integrators.
It supports DC 9V-36V wide voltage power supply, which adapts to unstable voltage surges widely existing in workshop power distribution, AGV robots and mobile handling equipment. Operators do not need to match additional voltage regulators, lowering auxiliary deployment costs.
Native Modbus RTU connectivity is the core highlight for industrial integration. Over 90% of on-site factory PLCs (Siemens, Mitsubishi, Delta, Allen‑Bradley) adopt Modbus RTU as default communication. Unlike generic RFID readers that require extra Modbus conversion modules, this model supports direct plug-and-play connection. System engineers can finish wiring and parameter debugging within 10 minutes, without third-party gateways, custom firmware or secondary coding. It cuts on-site integration labor time by 70% for both new assembly lines and old equipment renovation projects.
For dense parallel production lines where cross-reading frequently occurs, the YH-G9540 supports precise on-site antenna tuning. Technicians can limit the effective reading range accurately to isolate adjacent tag signals, preventing chaotic data collection and unexpected line shutdowns caused by misreading.
With an IP65 dustproof and waterproof enclosure, the reader maintains stable long-term operation in dusty, oily and humid workshop environments. It is widely applied in electronic part tracing, automotive workpiece assembly, tool fixture management and conveyor logistics identification scenarios.
On-site Practical Application Cases
1. Automotive Interior Assembly Line: Installed inside narrow robotic fixture gaps (only 42mm reserved mounting space). Thanks to its compact design and Modbus RTU protocol, it connected to Mitsubishi FX5U PLC directly without gateways. Antenna tuning limited reading range to 0.6m, solving cross-reading between two adjacent assembly stations 0.8m apart.
2. Workshop AGV Material Handling: AGV battery output voltage fluctuates between 11V-32V during movement. The wide 9-36V voltage input ensures uninterrupted tag reading during voltage spikes, eliminating intermittent reading failures that plagued ordinary RFID readers.
3. Electronic PCB Conveyor Line: Multiple readers arranged side by side on high-speed conveyors. Field technicians calibrated antenna gain individually, isolating mutual signal interference and guaranteeing 99.9% tag recognition accuracy for small PCB tags.
