{"title":"SCXL-MaxSonar-WRST7 (MB7574)","handle":"scxl-maxsonar-wrst7-mb7574","url":"/products/scxl-maxsonar-wrst7-mb7574","description":"The MB7574 SCXL-MaxSonar-WRST7 is a weather-resistant ultrasonic distance sensor designed for outdoor use. It provides millimetre-resolution measurements from 500mm to 5000mm with a 0.58Hz read rate, and includes three output options: analog voltage, TTL serial, and pulse-width.\n\nHoused in a compact IP67-rated PVC enclosure compatible with standard 3/4-inch PVC pipe fittings, the sensor features a self-cleaning transducer to reduce the impact of condensation and frost. Internal temperature compensation and real-time automatic calibration ensure accurate readings across varying environmental conditions.\n\nKey Features\n\n\nWeather Resistant (IP67) – Rugged PVC housing suitable for outdoor and high-moisture environments\n\nSelf-Cleaning Transducer – Reduces impact of condensation, frost, and debris\n\n1mm Resolution – High-precision distance measurements with rate-limiting filter\n\nThree Output Modes – Analog voltage, TTL serial, and pulse-width\n\nInternal Temperature Compensation – Accurate readings without external calibration\n\nReal-Time Automatic Calibration – Compensates for voltage, humidity, and ambient noise\n\nAdvanced Noise Rejection – Waveform signature analysis and continuously variable gain for clean readings\n\nNarrow Beam Pattern – Factory calibrated for long-range, focused detection\n\n\nSpecifications\n\n\nModel: MB7574 SCXL-MaxSonar-WRST7\n\nRange: 500mm to 5000mm\n\nResolution: 1mm\n\nRead Rate: 0.58Hz\n\nFrequency: 42kHz ultrasonic\n\nSupply Voltage: 2.7–5.5V\n\nCurrent Draw: 68mA average\n\nOutputs: Analog voltage, TTL serial, pulse-width\n\nOperating Temperature: -40°C to +65°C\n\nIngress Protection: IP67\n\nHousing: PVC, compatible with 3/4\" pipe fittings\n\nCompliance: RoHS\n\n\nIdeal For\n\nSnow depth and water level measurement\nWeather station monitoring\nOutdoor distance sensing and object detection\nIndustrial and environmental monitoring\n\n\n\nNote: Objects closer than 500mm are reported as 500mm.
