U630-M 9 dBi UHF integrated RFID reader, front view with two cable glands on the lower edge

U630-M 9 dBi UHF Integrated RFID Reader, 0–6 m, Rated to -40 °C

Q: Can the U630-M work in freezing conditions?

Yes. It is rated to operate from -40 °C to +65 °C and to be stored from -45 °C to +95 °C. In cold climates, allow about 15 minutes after power-on for the reader to warm up.

Q: How high should the U630-M be mounted?

Above 1.8 m, on a pole of 40–60 mm diameter or on a wall, tilted toward the point where the tag passes. Mount it with the arrow on the rear plate pointing up.

Q: What does the trigger input do?

In external-trigger mode, the reader reads only while the trigger input is active, for example when a loop detector senses a vehicle. In timed mode, it scans at a set interval without a trigger.

Q: How is the U630-M different from the U620-M?

The U630-M has a 9 dBi antenna and is rated for 0–6 m (10 m in high-power mode), against 8 dBi and 0–5 m (8 m) for the U620-M. Its housing is larger but thinner, at 257 × 257 × 42 mm, and it is rated down to -40 °C.

The U630-M is a 9 dBi integrated UHF RFID reader for outdoor vehicle and gate lanes, including cold sites: it is rated to operate from -40 °C to +65 °C. It reads EPC Gen2 tags at 0–6 m (up to 10 m in high-power mode) and reports over Wiegand 26/34, RS232/RS485, USB or, on the U630-N, TCP/IP.

Frequency: 902–928 MHz or 865–868 MHz, specified at order; other bands on request
Cards / tags: ISO 18000-6C / EPC Gen2 passive UHF tags (read and write)
Interface: Wiegand, RS232, RS485, USB
Output: Wiegand 26 / 34
Read range: 0–6 m; up to 10 m in high-power mode (depends on tag and site)

Available versions

U630-MN-type: Wiegand 26/34, RS232/RS485, USB
U630-NE-type: adds TCP/IP Ethernet (Wiegand 26/34, RS232/RS485, TCP/IP, USB)

Why integrators choose the U630-M

Rated from -40 °C to +65 °C — built for cold outdoor sites, with storage from -45 °C to +95 °C.
0–6 m, up to 10 m — a 9 dBi antenna and 0–30 dBm RF power cover a full vehicle lane.
Timed or external-trigger reading — scan at a set interval, or read only when the trigger input sees a loop detector or photo-beam.
Tag issuing demos — the software package has a test demo plus automatic tag-writing and tag-reading demos for issuing tags before installation.
Slim 42 mm panel — 257 × 257 × 42 mm and 1.45 kg, with four mounting studs on the rear plate for the pole or wall bracket.
Wiegand 26/34 plus serial — Wiegand to the controller, RS232/RS485 or USB to software, TCP/IP on the U630-N.

Installing the U630-M at a gate

Mount the reader higher than 1.8 m, on a pole of 40–60 mm diameter or on a wall, and tilt the panel toward the point where the tag passes. The metal rear plate has four studs for the bracket, and an arrow marks the top edge. The cables leave through two glands on the lower edge.

At cold sites, allow the reader about 15 minutes after power-on to warm up before you rely on its reads. Keep metal signs, barrier arms and parked vehicles out of the direct field where you can; our read range guide covers what else shortens range.

Timed reading or external trigger

In timed automatic mode the reader scans at a set interval and reports the tags it finds. That suits a gate where every tagged vehicle in range should be logged. In external-trigger mode it reads only when the trigger input is activated, for example by a loop detector under the lane. That keeps the reader quiet between vehicles and reduces reads from traffic passing on the road. Both modes are selected in the configuration software.

Issuing tags with the demo software

The software package includes a test demo and automatic tag-writing and tag-reading demos, so you can number windshield tags or cards before they are handed out. For batch issuing at a desk, the U120-U desktop reader/writer is easier to handle. The UHF tag writing guide explains the EPC, TID and user memory banks.

Integration in 4 steps

1
Fit the bracket to the four rear studs and mount the reader above 1.8 m on a 40–60 mm pole or a wall, top edge up as marked.
2
Bring the cables through the glands: DC 12 V, 3 A power, Wiegand D0/D1 to the controller or RS485/RS232 to the PC, and the trigger input if a loop detector is used.
3
In the demo software, choose timed or external-trigger reading and set RF power so the reader covers only the intended lane.
4
At cold sites, let the reader warm up for about 15 minutes after power-on, then test with real tagged vehicles before handover.
