Case verification
Confirm expected tagged contents before a carton proceeds to dispatch or packing.
Controlled conveyor read zones
RFID tunnel readers for dense, fast and repeatable conveyor applications
Enclose and control the read area around moving cartons, trays or tagged items for consistent automated capture and reduced cross-reads.

Tunnels
Multi-angle RFID coverage in a contained zone
RFID tunnels position several antennas around a conveyor and use physical containment to improve coverage while limiting reads beyond the intended zone. They are useful where tag orientation varies or cases contain multiple tagged items.
We integrate the tunnel with conveyor sensors, encoders, PLCs, stop/reject logic and the data destination so each read set is associated with the correct case or movement window.
System scope
Designed as a complete working solution
- Multi-antenna UHF/RAIN RFID arrays
- RF shielding and read-zone containment
- Photoeye and encoder triggering
- Case association and duplicate filtering
- Conveyor stop, divert or alarm outputs
- Stainless or industrial painted structures
Typical applications
Where tunnels create value
Conveyor tracking
Associate a defined set of tag reads with the correct moving tray, tote or carrier.
Bulk item capture
Read multiple tagged items inside a case where orientation is not fixed.
Exception handling
Stop, divert or flag cases when required identifiers are missing or unexpected.
Application engineering
Details that shape the specification
We assess the real items, movement, environment and target system before confirming the design.
01
Product composition
Liquids, foils and dense materials affect tag readability within a case.
02
Dwell time
Conveyor speed and tunnel length determine the available interrogation window.
03
Case separation
Sensor logic and physical gaps help assign reads to the correct container.
Frequently asked
Tunnels questions
Have a product, site or integration constraint not covered here? Speak directly with our team.
Ask Oxford TraceabilityWhy use an RFID tunnel instead of a single antenna?+
A tunnel can provide several read angles and better RF containment, which is valuable when tag position varies or multiple tags must be captured inside a case.
Can an RFID tunnel reject a failed carton?+
Yes. The RFID result can be passed to a PLC or conveyor control system to stop, alarm or divert a case using suitable downstream equipment.
What conveyor speed can an RFID tunnel handle?+
It depends on tag population, protocol settings, product materials, case spacing and required confidence. We determine this through calculation and representative trials.
