HRXL-MaxSonar-WR Series Ultrasonic Sensor Product Description
The HRXL-MaxSonar-WR sensor line is a cost-effective solution for applications requiring precision range-finding, low-voltage operation, space saving, low-cost, and IP67 rating for weather resistance.

The HRXL-MaxSonar-WR sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air. This sensor line features 1-mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-of-sound temperature compensation and optional external speed-of-sound temperature compensation. The HRXL-MaxSonar-WR/WRC models are available in 5-meter or 10-meter models. This ultrasonic sensor detects objects from 1-mm and ranges to objects from 30-cm to maximum range. Objects closer than 30-cm are typically reported as 30-cm. The interface output formats are pulse width, analog voltage, and digital serial in either RS232 (MB7360 series) or TTL (MB7380 series). Factory calibration is standard.

Precision Ultrasonic Range Sensing
? Range-finding at a fraction of the cost of other precision rangefinders
? Reading-to-reading stability of 1-mm at 1-meter is typical
? Accuracy is factory-matched providing a typical accuracy of 1% or better
? Internal temperature compensation is standard and optional external temperature compensation
? Determines range to largest object (MB7369 , MB7389)
? Determines range to first detectable object  (MB7360, MB7363, MB7366, MB7367, MB7380, MB7383, MB7386, MB7387)
? Excellent clutter rejection
? Additional chemical resistance available

Very Low Power Requirements
? Fast first reading after power-up eases battery requirements
? Wide, low supply voltage of 2.7V to 5.5V requirements eases battery powered design
? Low current draw reduces current drain for battery operation
? Very low-power rangerfinder, excellent for multiple sensor or battery based systems

Easy to Use Component Module
? Gracefully handles other ultrasonic sensors
? Stable and reliable range readings and excellent noise rejection make the sensor easy to use for most users
? Easy to use interface with distance provided in a variety of outputs
? Target size compensation provides greater consistency and accuracy
? Sensor automatically handles acoustic noise
? Calibrated sensor eliminates most sensor to sensor variations

Range Outputs
