1.940nm laser complies with Class 1 operation according to IEC .2.60825-1:2014, 3rd Edition Conditions.3.Sensor size (20x12.5x7.55mm)4.Maximum measurement range: 4 meters indoors, accuracy within 5%5.Measurement range is of target reflectivityThe TOF53400 ranging sensor, based on 's VL53L1X, is a laser ranging module that provides accurate and repeatable long-distance measurement. Thanks to its integrated leading-edge SPAD array (single-photon diode) and 's second-generation FlightSense technology, it achieves higher range, more accurate results, and improved immunity to ambient light interference. The TOF53400 also supports serial Modbus-RTU and IIC modes, making it well-suited for a variety of application scenarios.The TOF53400 has a range of up to 4 meters.Operates in high-infrared light environmentsHigh optical crosstalk compensationMeasurement time: less than 30msNo additional optical components requiredSingle power supplySupports serial port and IIC modesApplications:1.High-speed autofocus2.Continuous autofocus for video3.User detection for computers and other devices4.Obstacle detectionColor: BlackMaterial: plasticPackage Contents:1 x TOF53400 2m-4m Laser Distance Sensor ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
