HMI Display 4.3"
Compact HMI with physical keys or indicators
MO-662-L4 is the compact operator display for machine cabins: a 4.3" optically bonded screen with 4 soft keys or 4 indicators, an 800 MHz graphics MCU, CAN and configurable I/O on one sealed 18-pin connector. Analog camera, MP3 and Bluetooth music, FM/DAB radio and an internal speaker can be added as the cab needs them.
