E Series UR-E901 9 dBi Long Range UHF RFID Reader - Reliable 10m Read

In this review the E Series UR-E901 is evaluated as a dedicated UHF RFID reader for installations that need long read range and flexible connectivity. The reader is best for site integrators and facilities that require a stable, configurable fixed reader capable of handling inventory bursts while offering multiple interfaces. The biggest reason to consider it is the built-in 9 dBi circular polarized antenna paired with the M100 module, which delivers practical read distances up to 10 meter and a high inventory rate in a compact, wall- or pole-mount enclosure.

Key Features

• Frequency and output: Supports 902-928 MHz with software-adjustable RF output up to 30 dBm, allowing tuning for local regulations and range needs.
• Built-in antenna: The integrated 9 dBi circular polarized antenna simplifies installation and provides consistent reading of tags regardless of orientation.
• High inventory speed: The M100 module can inventory up to 100 tags per second, which is useful for rapid asset scanning or high-traffic checkpoints.
• Multiple interfaces: Includes RJ45, RS232, RS485, WG26/34, TTL and optional WiFi or 4G, enabling integration into diverse access control and monitoring systems.
• Flexible work modes: Active, answer and trigger modes let installers choose continuous, polled or event-driven reads for different workflows.
• Protocol support: ISO18000-6C and EPCglobal Class 1 Gen 2 compatibility ensures broad tag interoperability for most UHF deployments.

Who It's For

The UR-E901 is aimed at security integrators, warehouse and logistics teams, and access control projects that need a fixed UHF reader with reliable long-range performance and multiple comms options. Installers will appreciate the ABS enclosure sized for wall or pole mounting and the range of interface choices including RJ45 TCP support and WG26/34 for access control panels.

It is less suitable for casual hobbyists or tiny deployments that need a pocket reader or very lightweight setup. Also, projects requiring more than 20 tags read simultaneously for accurate per-tag timing should plan inventory strategies around the recommended concurrent tag count.

Pros & Cons

Pros

• Built-in 9 dBi circular polarized antenna delivers repeatable reads up to about 10 meter in typical conditions.
• Wide interface set (RJ45, RS232, RS485, WG, trigger) makes the reader adaptable to many systems without extra converters.
• High inventory speed with M100 module supports fast scanning workflows when tags are not overly dense.

Cons

• Recommended not to exceed about 20 tags read simultaneously for best reliability, so very dense tag fields need planning.
• Optional features like WiFi, 4G, HTTP, MQTT or LLRP are not standard and must be selected if required.

Frequently Asked Questions

Does this reader support TCP over Ethernet?
Yes; the RJ45 port supports TCP client and server modes plus Modbus, DNS and DHCP for networked deployments.

What tag protocols are supported?
It supports ISO18000-6C and EPCglobal Class 1 Gen 2, covering most UHF tags used in logistics and access control.

Can it be pole mounted outdoors?
The ABS enclosure and mounting options include wall or pole mounting, but outdoor installations should consider appropriate sheltering and local regulatory limits on RF output.
