AUTOID UF40 — fixed UHF RFID reader
SEUIC AUTOID UF40 is a stationary UHF RFID reader for building inline identification at receiving/dispatch gates, in conveyor tunnels and in control areas of warehouses and production. The reader automatically reads RFID tags without operator intervention , generating a real-time data stream.
Strengths for business
-
Inline operation without an operator. Stable reading at flow rate – less manual intervention, higher throughput.
-
Multi-antenna architecture. Connecting multiple antennas (top/sides) to cover “dead zones” and unstable tag orientation.
-
Anti-collision and density. Correct reading of tag packages in carts, boxes and on pallets.
-
Flexible integration. PoE Ethernet for power/networking (where available), IO/PLC triggers — synchronization with sensors and conveyor.
-
UHF standards. Support for EPC Class 1 Gen2 / ISO 18000-6C ( specify for your configuration ).
-
Computing base. Impinj E710 configurationsavailable by specification – please inquire.

Where UF40 gives the most
-
Warehouses/3PL: receiving/shipping gates , flow control, on-the-fly inventory.
-
E-commerce/distribution: automatic batch reconciliation and routing.
-
Production: tracking containers/carts/parts, control of process stages.
-
Retail back office: quick inventory of boxes and containers.
How it works on the line (briefly)
-
Sensor/PLC or timer triggers → UF40 starts reading cycle.
-
A reader with multiple antennas collects tags, applies anti-collision , filters/masks.
-
The result (EPC/time/signal level) is fed into your WMS/ERP; the event is driven by a semaphore/sort .
Why SEUIC AUTOID UF40
-
Stationary UHF RFID reader with focus on gate/conveyor .
-
PoE + IO/PLC = quick start into an existing cycle.
-
Scalability: easy to expand the reading area with additional antennas/readers.
-
Service and selection. We will help you design a coverage area and conduct a test on your case.
FAQ
Does the UF40 support multiple antennas?
Yes, multi-antenna operation is supported ( the number of ports depends on the configuration ).
What UHF standards are supported?
Typically EPC Class 1 Gen2 / ISO 18000-6C ( specify in your specification ).
How to synchronize with a conveyor/sensor?
Through IO/PLC triggers ; the reader starts a reading cycle based on an event.
Is it possible to expand the coverage area?
Yes: use multiple antennas and/or multiple readers in a common area.
Are there any configurations on the Impinj E710?
Yes, available by specification ; please specify for your case.
