## Description

The MB7076 XL-MaxSonar-WRLA1 is a weather-resistant ultrasonic ranging sensor with centimetre resolution and a 10 Hz read rate. It detects the nearest target from 20 cm to 1068 cm (over 10 metres) and provides three output options: analog voltage, analog envelope, and RS232 serial. Housed in a rugged PVC enclosure rated to IP67, this sensor matches standard 3/4-inch PVC pipe fittings for easy outdoor mounting. Factory-calibrated narrow beam patterns and advanced noise rejection algorithms deliver reliable, virtually noise-free distance readings even in challenging acoustic or electrical environments. Key Features IP67 Weather Resistant – Rugged PVC housing for outdoor use 20 cm to 1068 cm Range – Long-range detection with 1 cm resolution 10 Hz Read Rate – Fast, continuous distance updates Three Output Modes – Analog voltage, analog envelope, and RS232 serial Advanced Noise Rejection – Real-time automatic calibration for voltage, humidity, and ambient noise 42 kHz Ultrasonic Sensor – Narrow beam pattern for focused detection Low Power – 3.4 mA average current draw Standard Pipe Fitting – 3/4″ NPT compatible for easy mounting Specifications Detection Range – 20 cm to 1068 cm Resolution – 1 cm Read Rate – 10 Hz Frequency – 42 kHz Operating Voltage – 3.0–5.5 V Average Current – 3.4 mA Outputs – Analog voltage, analog envelope, RS232 serial Operating Temperature – -40°C to +70°C Ingress Protection – IP67 Mounting – 3/4″ NPT (standard electrical PVC pipe fitting) MTBF – 200,000+ hours Compliance – RoHS Ideal For Outdoor distance measurement and level sensing Weather station and environmental monitoring Autonomous vehicle obstacle detection Industrial automation and tank level monitoring Package Contents 1× XL-MaxSonar-WRLA1 (MB7076) Ultrasonic Sensor Resources XL-MaxSonar-WR Datasheet (PDF)
