Chainway - UR4 Fixed RFID Reader

Four antenna ports in a 10 cm housing – the fixed UHF reader for stationary read points

Order the Chainway UR4 and you receive a full 4-channel fixed UHF RFID reader that delivers the performance of much larger devices in a compact aluminium enclosure. The UR4 is built for stationary read points: gate and portal applications, scan tunnels, conveyor read zones, access management installations and overhead read points are all covered by a single SKU. The reader connects to existing PLCs, ERP systems or middleware through RS-232 or 10/100 Base-T Ethernet – no proprietary cabling, no host PC required.

The core engine is the CM710-4 module built around the Impinj E710 chipset, including support for the latest Impinj Gen2X protocol. Output power reaches 1 W (30 dBm) and is fully adjustable in 1-dB steps from +5 to +30 dBm – allowing operators to tune each antenna port to its specific read zone. Receive sensitivity below −84 dBm and a peak inventory rate of more than 900 tags per second make the UR4 a practical choice for dense tag populations in dock door, conveyor and tunnel applications.

At 102.8 × 102.8 × 28 mm and 329 g, the housing is small enough for unobtrusive wall, ceiling or in-cabinet installation. Powered via DC 9–12 V or optional PoE (802.3af, 13 W) or PoE+ (802.3at, 25.5 W), deployment can be reduced to a single network cable per read point – simplifying both installation and maintenance.

The aluminium alloy enclosure is engineered for electromagnetic robustness and passive cooling, eliminating the need for fans even in continuous 24/7 operation between −25 °C and +65 °C. Standby current sits below 30 mA, working current at 800 mA @ 12 V – figures that qualify the UR4 for fanless cabinet installations where heat and noise budgets are tight.

Technical Highlights

• EPC Global UHF Class 1 Gen 2 / ISO 18000-6C protocol – full compatibility with all standard RAIN RFID tags and transponders on the market
• Impinj E710 chipset with Gen2X support – peak inventory rate above 900 tags/sec for dense bulk reading
• 4 antenna ports (50 Ω SMA) – up to four independent read zones per reader, compatible with 6 dBic and 9 dBic antennas
• Optional PoE / PoE+ plus RS-232 and 10/100 Base-T Ethernet – single-cable deployment and flexible host integration
• 30 dBm (1 W) adjustable in 1 dB steps, sensitivity < −84 dBm – precise field tuning to avoid cross-reads between adjacent zones

Applications

• Gate and portal read points in warehousing and logistics – four separate zones from a single device
• Scan tunnels and conveyor lines in production and shipping – fast bulk reads enabled by Gen2X
• Access and asset management in banking, libraries and archives – discreet wall mounting through the slim aluminium chassis
• Apparel, jewellery and watch retail, laundry tracking and medical instrument cabinets - stable 24/7 operation in indoor environments

The Chainway UR4 is the right choice when a compact fixed reader has to be integrated into existing installations without compromising on performance. SDKs for Windows, Linux and Android allow a smooth handover to almost any software environment – from custom WMS integrations to direct coupling with cloud platforms. The GPIO interface, with two opto-isolated inputs and an electrical relay output, enables tight integration with light barriers, signal lamps, switches or door controls – delivering fully automated read points without an intermediate PC.

In total, the UR4 packages mid-range fixed-reader performance into a chassis of just 10.3 × 10.3 cm. Features such as antenna detection, RSSI reporting and ambient temperature monitoring are fully integrated and can be queried through the SDK - valuable diagnostic data when operating larger networks of read points.

Order the Chainway UR4 from IDCRAFT together with expert advice on the right antenna configuration, regional frequency band (865–868 MHz for EU, 902–928 MHz for US, 920–925 MHz for additional markets) and power supply option. For higher-volume projects we are happy to issue a custom quote including mounting accessories, antennas and matching tags or labels.
