AA121SL11 MITSUBISHI 12.1 inch display modules
Mitsubishi AA121SL11 is a rugged 12.1-inch SVGA industrial TFT LCD module designed for 24/7 continuous operation in complex factory environments. Equipped with dual CCFL backlight and mature TN liquid crystal structure, it delivers stable 350 cd/m² brightness and 400:1 contrast ratio to ensure clear text, curve graphics and data visualization under various workshop light conditions. It adopts universal single-channel 6-bit TTL parallel 41-pin interface, which is highly compatible with traditional PLC mainboards, CNC controllers and legacy industrial HMI drive boards without complicated signal conversion circuits. Its ultra-wide operating temperature from -20℃ to +70℃ supports deployment in cold processing workshops, heavy machinery workshops and semi-outdoor industrial terminals. The front surface features 2H anti-reflection hard coating, effectively reducing ambient light reflection and resisting minor surface abrasion during daily industrial operation. As an original Japanese Mitsubishi industrial display, this model is widely used as a direct replacement screen for aging automation equipment, fully RoHS compliant and supplied with complete factory inspection certification for global industrial maintenance and renovation projects
