IP67 Vehicle-Mounted UHF RFID Reader
RLFL-4P UHF RFID Forklift Reader
Automate pallet and material identification from the forklift. RLFL-4P connects up to four external antennas and uses sealed vehicle-mounted connections, wide-voltage power input and industrial I/O to capture compatible RFID events during pickup, putaway, transfer and loading workflows.
* Tag rate, read range and vehicle-read reliability depend on antenna selection, cable loss, tag design, tagged material, orientation, RF settings, nearby metal, movement speed, trigger logic and operating environment.

Why Use RLFL-4P?
Move pallet identification into the normal forklift workflow
Use RLFL-4P when RFID capture should happen close to the forks, mast or handled load instead of requiring the driver to stop and scan every pallet manually.
Reduce repeated pallet scans
Capture compatible pallet, container or material tags during pickup, transfer, putaway or loading—reducing repeated barcode and item-by-item scanning.

Protect vehicle-mounted connections
Use an IP67 aluminum enclosure and locking aviation connectors to protect the reader, power, communication and control wiring in dusty or wet industrial environments.

Connect events to warehouse systems
Send tag data to a vehicle terminal, warehouse application, WMS, MES, middleware or custom host through the supported wired or wireless interfaces.

Before / After
From stop-and-scan verification to forklift-mounted RFID capture
Replace a separate manual scanning step with a configured read area that captures compatible tags while the operator performs the normal material-handling task.
Manual pallet verification
Five repeated actions for each load

The operator interrupts the handling task and completes a separate identification step for every pallet or container.
RLFL-4P RFID capture
Three stages in the configured handling workflow

RLFL-4P captures and transmits RFID data. Pallet-to-task matching, location confirmation, route logic, exception handling and WMS/MES updates must be implemented in the connected vehicle terminal, host application, middleware or business system.
Forklift-Mounted RFID Capture
Position four external antennas around the forks, mast and handled load
Use the four RLFL-4P antenna ports to build a vehicle-specific read area. Antennas may be positioned around the load-handling structure according to the pallet tag position, forklift geometry, cable route and intended capture direction.
Route each external antenna toward the handled pallet, container, material or vehicle-side detection area required by the workflow.
Fork & Load Area
Position an antenna close to the pallet or container being picked up, carried or placed.
Mast-Side Coverage
Use a protected mounting position around the mast according to movement clearance and metal structure.
Left / Right Load Coverage
Use multiple antennas when the pallet tag may appear on different sides or orientations.
Approach or Transfer Point
Configure an antenna toward the intended pickup, transfer, staging or loading direction.
Four antenna ports do not automatically create four isolated read zones. Real separation depends on antenna pattern, position, shielding, RF power, cable loss, forklift metal, load material, tag orientation, spacing and site conditions.
Forklift RFID System Architecture
Move pallet identification from the vehicle to the warehouse workflow
RLFL-4P captures compatible tag responses. Trigger logic, task validation, location context, storage and business actions belong in the connected vehicle terminal, controller, middleware or warehouse system.
Tagged Pallet or Container
A compatible UHF RFID tag enters the configured vehicle-mounted read area.
External Antennas
The selected antenna positions create the project-specific RF coverage around the load.
Trigger or Vehicle Signal
A sensor, switch, vehicle signal or host command starts the approved read workflow.
RLFL-4P Reader
RLFL-4P processes compatible tag responses and sends the captured data outward.
Vehicle Terminal or Controller
The connected computer or controller receives the reader event and applies project logic.
WMS / MES / Warehouse App
The business platform records or acts on the validated pallet, task or movement event.
Vehicle & System Integration
Connect antennas, vehicle power, trigger signals and host communication
Use the RLFL-4P sealed cable system and supported interfaces to integrate RFID capture with sensors, vehicle terminals, industrial controllers, status devices and warehouse software.

Deployment Guidance
Design around the forklift, antenna, tag, power and movement
RLFL-4P does not create a controlled pallet-read zone by itself. Forklift metal, antenna position, tag placement, cable routing, trigger timing, RF power, load materials and vehicle motion determine actual performance.
Start with the handling task and target pallet, then select the antenna positions, trigger method, cable route and host integration around the real vehicle.
Account for the forks, mast, carriage, safety clearances, tag side and likely pallet orientations.
Confirm vehicle power quality, electrical protection, connector locking, abrasion protection, bend radius and cable movement.
Test the actual tags, pallets, materials, vehicle, approach direction, trigger timing, speed and neighboring inventory.

RLFL-4P selection, mounting and workflow questions
What makes RLFL-4P suitable for forklift installation?
RLFL-4P combines an aluminum IP67 enclosure, locking aviation connectors, four external antenna ports, DC 9–30 V input, wired and wireless communication, and industrial I/O. The final installation still requires approved mounting, electrical protection, cable routing and validation.
Is the complete RLFL-4P reader and cable system waterproof?
The supplied specification lists IP67 for the RLFL-4P enclosure. Complete installed protection depends on using the specified connectors, mating plugs, seals, cables and unused-port caps correctly.
How many external antennas can RLFL-4P connect?
RLFL-4P provides four external antenna ports. Select the final antenna count and position around the forks, mast, handled load, tag location, cable route and target direction.
Can RLFL-4P identify only the pallet currently being handled?
That is a system-design objective, not an automatic guarantee. Use suitable antennas, controlled RF power, careful mounting, shielding where practical, trigger timing, tag placement and host logic to reduce adjacent reads.
What affects tag capture while the forklift is moving?
Performance depends on antenna pattern and polarization, tag design, pallet material, tag orientation, cable loss, RF power, vehicle metal, movement speed, trigger timing, distance, interference and nearby tagged inventory.
Can a sensor or vehicle signal trigger RLFL-4P reading?
The supplied specification lists four optocoupler inputs. A sensor, switch, controller or vehicle-state signal may be used after the signal level, connector pinout, ownership and timing are confirmed.
How many input and output channels are available?
RLFL-4P is specified with four optocoupler inputs and four relay outputs. The relay outputs are listed for DC 0–30 V / 1 A.
Can RLFL-4P connect to a vehicle terminal or industrial computer?
Ethernet, RS-232 and RS-485 are listed, together with Wi-Fi and Bluetooth. Select the interface according to the terminal and host application, then confirm the final cable assembly and protocol.
Can RLFL-4P data be sent to WMS, MES or ERP software?
Yes, through a vehicle terminal, host application, middleware, industrial controller or custom integration. RLFL-4P should not be presented as a native WMS, MES or ERP connector unless a specific software connector is confirmed.
Does RLFL-4P support Wi-Fi and Bluetooth?
Built-in Wi-Fi and Bluetooth are listed in the supplied specification. Confirm the wireless versions, antenna configuration, operating mode and ordered hardware revision before publication or quotation.
What power supply does RLFL-4P require?
RLFL-4P is specified for DC 9–30 V, with power-supply capacity greater than 30 W. Vehicle installations should also review reverse-polarity protection, surge protection, vehicle transients, grounding, fusing and shutdown behavior.
How should RLFL-4P cables be routed on the forklift?
Keep cables away from pinch points, moving mast components, sharp edges, heat and driver controls. Use strain relief, abrasion protection, suitable bend radius, connector locking and service loops.
Should the stated read range of up to 20 m be the forklift design target?
Usually not. Forklift projects commonly need a controlled read area close to the handled load rather than maximum distance. Tune antenna placement and RF power to capture the intended pallet while reducing adjacent reads.
Does RLFL-4P support MQTT, local caching or edge applications?
No MQTT client, local event cache, on-reader database, edge runtime or business-rule engine is confirmed in the supplied specification. Implement these functions in a connected terminal, middleware or host system unless another firmware option is documented.
Which RLFL-4P regional frequency version should be ordered?
Select the version that matches the deployment region. The supplied specification lists FCC 902–928 MHz, ETSI 865.6–867.6 MHz and China 920–925 MHz. Confirm regulations and firmware before shipment.
