CODE: Nundnet NT 920 PXY

UHF RFID long range reader, NT 920 PXY is a specially designed and developed device that can sense the UHF RFID tags EPC Gen II (ISO 18000 – 6C), ISO 18000-6B from the distance of 20Meters under ideal conditions. The built in antenna gain at 12dBi and RF module with 30dB makes it suitable for long range sensing of compatible tags and cards. Being IP65 rated, the device is capable to withstand the environmental changes as it fully protected against dust and low pressure jets of water from all directions with limited ingress permitted. The compatible frequency ranges are 865~ 868 MHz while as can be customized for special frequency band spectrum of 902 ~ 928 MHz Multiple communication like TCP/IP port, Wiegand (Universal communication port), RS232, RS485 ports can be incorporated as a feature. The reader is compatible with Nundprox U series of UHF RFID cards and tags.

Additional information


Nundnet NT 920P is developed & designed for easy integration into existing digital & electronic management systems in the industry, viz.a.viz access controls, car parking & vehicle access control, retail & property management, ID access control for offices and private buildings, Hand-free operation. Communication interfaces are RS 232, RS 485 for serial communication, open standard industrial protocol
wiegand and TCP/IP.


Nundnet NT 920P uses Amplitude-shift keying (ASK), that represents the digital data as variations in the amplitude of a carrier wave. Here the binary symbol 1 is represented by transmitting a fixed-amplitude carrier wave & fixed frequency for a bit duration of T seconds. If the signal value is 1 then the carrier signal will be transmitted; otherwise, a signal value of 0 will be transmitted. This is the most sophisticated scheme of modulation which represent the data in groups using an additional amplitude levels

ISO 18000-6B

It defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz ~ 960 MHz Industrial, Scientific, and Medical (ISM) band used in item management
applications. It provides a common technical specification for RFID devices.

ISO 18000-6C

It defines air interface parameters for tags operating within the frequency range of 860–960 MHz and allows for use of different frequencies in different regions from within this range. Nundnet NT 915 P offers frequency range of 902~ 928 MHz, 865 ~ 868 MHz, 922 ~ 928 MHz.


NT 920P enclosure can be subjected to a jet of water from a nozzle of 6.3 mm diameter from all the directions. The test duration is 15 minutes for 12.5 liters per minute at pressure of 30 kPa at distance of 3 m. Hence IP 65 rating means that water cannot penetrate into the device in such a quantity or in such a position that can prove risky for operation of unit. IP66 insures the protection from total dust ingress & high pressure water jets from any direction.


Nundnet NT 920 P are designed to sense Gen 2 EPC global are multiple frequencies from 860 ~ 960 MHz. Ultra High Frequency (UHF) Passive RFID Tags, and an ideal sensing range unto 20 Meters.


Nundnet NT 920P equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. This device is designed to provide the reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
