20 m Long-Range UHF RFID Reader, 12 dBi, Wiegand & RS485: overview
The LR-140 is the large-panel sibling of the LR-130, built for vehicle lanes where tags have to be read 10–20 m from the reader. A 12 dBi linear-polarized antenna shares a 445 × 445 mm IP66 housing with the reader electronics and a seven-color status LED, so each gate needs only the reader, a 9–15 V DC supply and a cable run to the controller.
Tag IDs leave the reader over Wiegand or RS485, ready for access controllers, parking controllers or barrier logic boards. Reading can run continuously or start on a trigger such as a ground loop that detects a car in the lane. RF output spans 19–30 dBm, giving installers room to trim the read zone on sites with adjacent lanes.
Two option levels are offered in each band. The base version uses USB for configuration; the -NET-BT version adds a TCP/IP port for networked parking software and BLE 5.1 for configuration at about 0–3 m. Order the EU version for 865–868 MHz markets, or the US version, which covers the 902–928 MHz band and ships set to 902–906 MHz, adjustable in the configuration tool.
Integration notes
At 12 V the reader draws up to 500 mA on standby and up to 1200 mA while reading, so plan the supply for the higher figure. The housing is 86.2 mm deep; allow for that when choosing a pole or gantry position. The 10–20 m figure comes from a handheld card test, so windshield tags, coated glass and mounting angle will move the real read point. The front carries a printed vehicle icon.

Where the LR-140 is used
- Gated community main entrance, reading resident windshield tags well before the barrier arm
- Industrial site gate where trucks are identified on the approach and logged over TCP/IP
- Wide two-lane entrance covered by one reader mounted on a central island
- Hotel or hospital car park that triggers reading from a loop detector to avoid reads from passing traffic
Apartment, Multifamily & Rental Property Access Control
Apartment building access control hardware: anti-clone readers with matched fob sets, QR visitor codes, 4G controllers for rentals and UHF tags for gates.
LR-140 FAQ
When should I choose the LR-140 instead of the LR-130?
Choose the LR-140 when the read point needs to be 10 m or more from the reader, for example on wide gates or approach roads. Where 2–10 m is enough, the smaller LR-130 is easier to mount.
Does antenna polarization matter?
Yes. A linear-polarized antenna gives its best range when the tag antenna is aligned with it, so fit windshield tags in the same position and orientation across the fleet.
What does the -NET-BT option add?
A TCP/IP port for sending tag data to software on your LAN, plus BLE 5.1 for changing settings within about 0–3 m. Wiegand and RS485 remain available.
What power supply should I use?
A regulated 9–15 V DC supply able to deliver at least 1.2 A per reader at 12 V, because working current can reach 1200 mA.
