PRACTICAL FIXED RFID FOR EVERY DOORWAY & CONVEYOR

Automate Goods In, WIP Cells & Dispatch Portals Across Every Bay

Many UK businesses hold back from automating secondary internal doorways, returnable tote wash lines, or archive room thresholds because flagship 8 port readers feel over specified for a 2 antenna or 4 antenna choke point. The compact Unitech RS804 hits the sweet spot of industrial reliability and scalable deployment.

FANLESS ZERO MAINTENANCE HARDWARE

Solid State Cast Aluminium Survives Dusty Industrial Roof Spaces

Mounted 3.5 metres above warehouse roller shutters or beside cardboard conveyors, cooling fans fail quickly. The RS804's passive aluminium heatsink runs cool 24/7 from -20°C to +50°C.

TECHNICAL & COMMERCIAL FAQS

RS804 Buyer & Engineering FAQs

How many doorways or zones can one Unitech RS804 cover?

With 4 RP-TNC ports, one RS804 typically drives a full 4 antenna loading bay dock portal (two antennas per side) or two separate 2 antenna internal corridor/conveyor checkpoints.

Does the RS804 work with any standard UHF RFID panel antenna?

Yes, it uses industry standard 50 Ohm RP-TNC connectors compatible with circular and linear UHF panel, shelf, and mat antennas.

Can it trigger an alarm or light tower without a PC at the doorway?

Yes, its Embedded Linux OS and 4×4 opto isolated GPIO ports drive 24V beacons, buzzers, and door relays directly.
