Product Overview
The Omron NB3Q-TW00B is a 3.5-inch programmable terminal from the NB-series HMI family, manufactured by Omron Corporation. Hengyixin Automation ships this HMI panel from Xiamen with the NB-Designer project file on a USB drive included.
The display is a 3.5-inch TFT color LCD at QVGA 320 x 240 pixel, showing 65,536 colors with an analog resistive touch panel rated for 1,000,000 operations. Internal memory is 128 MB including the system area. Serial COM1 is RS-232C / 422A / 485 (not isolated) on a D-Sub 9-pin connector, with 15 m max on RS-232C and 500 m max on RS-422A / 485.
USB Host (Type-A, 5 V / 150 mA) accepts a USB stick for project upload and data logging; USB Slave (Type-B) handles PC project download. There is no Ethernet on this model. The NB3Q series is now discontinued; the recommended modern replacement is the NA5-7W001B-V1. The NB3Q-TW01B sibling adds an Ethernet port on the same body. Programming is in NB-Designer from version 1.20.

Best-Fit Applications
- Compact operator panel on a small benchtop injection molding machine where the 3.5-inch screen fits in the limited console space
- Spare replacement on a CP1L-M30DR-A controlled conveyor where the existing serial-only NB3Q project is still maintained on NB-Designer
- Low-cost visualisation terminal on a coffee-roaster PLC cabinet that needs a colour touchscreen without Ethernet connectivity
Buying Checklist
- Pick the NB3Q-TW00B for a discontinued 3.5-inch NB-series TFT color HMI on serial RS-232C / 422A / 485 with 128 MB and IP65 front face.
- Pick the NB3Q-TW01B instead when the same 3.5-inch body needs an Ethernet port for EtherNet/IP or Modbus-TCP.
- Pick the NA5-7W001B-V1 instead for the modern Sysmac Studio 7-inch replacement on new installations.

FAQ for NB3Q-TW00B
Does the NB3Q-TW00B have Ethernet?
No. This model has a serial COM1 (RS-232C / 422A / RS-485) and two USB ports only. For Ethernet on the same 3.5-inch body, pick the NB3Q-TW01B.
Is the NB3Q-TW00B still in production?
No. The NB3Q series is discontinued by Omron. The recommended modern replacement on Sysmac Studio is the NA5-7W001B-V1 (7-inch widescreen, EtherNet/IP, black bezel). Hengyixin Automation continues to ship factory-sealed surplus and new-old-stock units while inventory lasts.
What software programs the NB3Q-TW00B?
NB-Designer from version 1.20. Projects transfer over USB slave or the D-Sub serial port. CX-Designer projects are not compatible with NB-Designer.
NB3Q-TW00B vs NB5Q-TW00B - what is the difference?
The NB3Q is the 3.5-inch QVGA model. The NB5Q is the 5.6-inch QVGA model on the same NB-Designer platform with the same 128 MB memory and serial-only COM1. Pick the NB3Q for tight panels and the NB5Q for higher-visibility operator stations.
