TOPCON OPUS B2s 4.3″ Display with Softkeys

Are you looking for an HMI with high performance, perfect readability and customer-friendly handling regarding installation and programming? Then, the B series from Topcon Electronics is the right choice, even for your demanding applications! Two entry-level displays with 4.3″ and 7″ have been added to the B series. The simple design of the existing B devices is maintained, as well as the optically bonded display. The B2 and the B2+ come with an i.MX6 ULL processor with up to 528 MHz, 2 GB mass storage and 256 MB RAM. The HMIs impress users with their terrific price-performance ratio and extensive range of features. A screen brightness of up to 900 cd/m² allows readability even in direct sunlight. The capacitive touchscreen and the fully guaranteed reading angle of up to 80 degrees ensure a smooth operation.
