156-M28 industrial 15.6″ panel-installation monitor with IP65 front, HDMI/VGA/DP

156-M28 – industrial 15.6″ monitor for panel installation with IP65 front protection and HDMI/VGA/DP interfaces. 

The 156-M28 is a 15.6-inch industrial monitor designed for panel installation in demanding automation, machine-control and HMI environments. Built with a robust aluminum alloy enclosure, an ultra-thin 3 mm bezel and a fully enclosed fanless structure, it delivers strong resistance to dust, oil contamination, vibration, EMI interference and temperature fluctuations. According to the product datasheet, the device uses an industrial-grade controller board to ensure stable 24/7 operation in harsh conditions. 

15.6″ Full HD display – 300 cd/m² brightness, 800:1 contrast and wide 85/85/85/85° viewing angles

The monitor features a 15.6″ TFT LCD panel with a 1920×1080 (Full HD, 16:9) resolution, 300 cd/m² brightness and 800:1 contrast ratio. As shown in the Screen Parameter table, the panel provides wide 85/85/85/85° viewing angles, ensuring excellent visibility from any operator position. This makes the 156-M28 a strong choice for SCADA visualizations, HMI dashboards, process monitoring, production lines and industrial control rooms.
