📌 What is the eSSL U12‑I UHF RFID Reader?
The eSSL U12‑I is a fixed, integrated UHF RFID reader that combines a powerful RF module, a 9dBi circular polarized antenna, and a durable IP65 housing in a single compact unit. It is designed for passive UHF tags compliant with EPCglobal Class 1 Gen 2 and ISO 18000‑6C standards, making it compatible with windshield tags, employee ID cards, pallet tags, and industrial hard tags. The reader is powered by the latest Impinj E310 chip, delivering high‑speed inventory (over 350 tags/s) and reliable long‑range detection up to 12 meters.
The 33 dBm adjustable radio frequency output allows users to fine‑tune read range and power consumption for specific deployment scenarios. The integrated antenna eliminates external cabling, simplifying installation at vehicle gates, warehouse portals, and checkpoints. With a compact footprint of 258 mm × 258 mm × 83 mm and a weight of only 1.87 kg, the U12‑I can be wall‑mounted or pole‑mounted without requiring extensive structural reinforcement. Its IP65 protection rating guarantees reliable performance in outdoor installations subject to rain, dust, and extreme temperatures (-25 °C to +65 °C).

🔑 Core Features – eSSL U12‑I UHF Reader
The latest‑generation Impinj E310 chip powers the U12‑I, providing an inventory peak speed exceeding 350 tags per second. This ensures smooth, high‑throughput reading for logistics portals, vehicle gates, and high‑traffic access points.
The built‑in 9dBi circular polarized antenna delivers uniform tag detection up to 12 meters, regardless of tag orientation. This wide coverage simplifies installation and ensures consistent read rates for vehicle windshields, pallets, and personnel credentials.
Fine‑tune the output power from 0 dBm to 33 dBm to match specific site requirements and minimize interference between adjacent lanes. Optimise read range and power consumption without external amplifiers.
Rated IP65, the U12‑I is dust‑tight and protected against powerful water jets. Its rugged aluminium and PC+ABS housing withstands rain, snow, dust, and temperature extremes, making it suitable for exposed outdoor installations.
Includes 10/100 Base‑T Ethernet (default), optional Wiegand 26/34 for direct connection to access control panels, and optional RS232 for industrial automation. Four GPI inputs and four relay outputs allow direct control of boom barriers, traffic lights, sirens, and gate controllers.
Maximum power consumption of just 6.75 W (peak) and standby consumption of 1.76 W reduce operating costs while maintaining high processing speeds. Powered by 12 V DC, 2 A.
The reader can cache up to 1000 tag EPCs at 96 bits, ensuring no reads are missed during high‑traffic events such as multiple vehicles approaching a gate simultaneously.
A comprehensive SDK (C, C#, .NET, Java) and API documentation are provided, allowing developers to embed the U12‑I into custom access control, parking billing, or ERP platforms.
🏢 Where to Deploy the eSSL U12‑I UHF Reader
Install the U12‑I at residential and commercial parking entries. Read UHF windshield tags from up to 12 m, automatically opening boom barriers without needing drivers to stop or roll down windows.
Mount the reader at loading dock doors or warehouse portals to scan pallet and container tags in transit. The 350+ tags/s read speed supports high‑volume inbound/outbound scanning, feeding data directly into WMS or ERP systems.
Track tools, work‑in‑process, and returnable transport items through yard checkpoints. The IP65 rating withstands dust, moisture, and temperature extremes common in industrial environments.
Authorize employee and resident vehicles automatically, integrating with access control panels via Wiegand output. Log all entries for security and tenant billing records.
Process vehicles at high speed with 12 m read range and 350+ tags/s performance. The reader‘s I/O can directly trigger toll barriers, traffic lights, and video capture systems.
Identify ground support equipment, baggage carts, and cargo containers without requiring vehicles to stop, improving operational efficiency and reducing manual scanning.
