The Omron NT31ST-122EV2 is an operator interface designed to meet diverse control requirements in various environments. Displaying information on a STN monochrome screen, it features a resolution of 320 x 240 dots, which makes it suitable for applications that require clear visibility in a compact footprint of 118 x 89 mm. This unit utilizes a pressure-sensitive touch panel, where users can engage with up to 192 touch switches arranged in a 16 by 12 layout. Each switch requires a maximum operating force of only 1 N, making it user-friendly and efficient.

This unit is built to last, with a service life of at least 1,000,000 operations, ensuring reliability over extended usage. It operates at a supply voltage of 24 VDC and supports a power supply voltage range between 20.4 and 26.4 VDC. Its power consumption does not exceed 18 W, thus promoting energy efficiency.

In terms of environmental tolerance, the NT31ST-122EV2 can function efficiently within an operating temperature range of 0 to 50 °C and can be stored in temperatures as low as -20 °C and up to 60 °C. The device can handle humidity levels between 35% and 85%, provided that no condensation occurs.

For added durability, the NT31ST-122EV2 also includes noise immunity, conforming to IEC 61000-4-4 standards at a level of 2 kV on the power supply line. To withstand operational demands in various settings, it demonstrates vibration resistance, effectively handling frequencies from 5 to 9 Hz with a single amplitude of 3.5 mm, and from 9 to 150 Hz with a maximum acceleration of 9.8 m/s².
