• Model & Content: Product choices include 1 MLX90640ESF BAB (55 x 35 degree) or 1 MLX90640ESF BAA (110 x 75 degrees); Part Name MLX90640ESF and TO39 Four-Pin Packaging are specified for clear selection.
• DETAILED INFRARED ARRAY - 32x24 infrared pixel layout maps temperature on a scene for applications such as personnel positioning, thermal comfort sensing and visual infrared thermometers, with target detection from 40°C to 300°C.
• Accurate Detection & Low Noise - The NETD of 1K RMS at 1Hz provides reliable detection of subtle temperature differences for intrusion and motion detection in building automation and security systems.
• User-friendly Interface: I2C-enabled digital interface and programmable refresh rate (5Hz to 64Hz) simplify connection to microcontrollers; 3.3V power supply and operating current less than 23mA reduce power on embedded projects.
• Field of View Selection for Applications: Two field of view choices allow you to choose a narrow angle of 55 x 35 degrees for targeted measurement or a width of 110 x 75 degrees for area coverage, applicable to HVAC sensors, driver comfort systems, and industrial parts monitoring.
