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. *For select sensors this distance is 50-cm, refer to pages 4 and 5.

Close Range Operation

Applications requiring 100% reading-to-reading reliability should not use MaxSonar sensors at a distance closer than

50cm. Although most users find MaxSonar sensors to work reliably from 0 to 50cm for detecting objects in many

applications, MaxBotix

Inc. does not guarantee operational reliability for objects closer than the minimum reported

distance. Because of ultrasonic physics, these sensors are unable to achieve 100% reliability at close distances.

HRXL-MaxSonar® - WR/WRC™ Series About Ultrasonic Sensors The HRXL-MaxSonar-WR ultrasonic sensors are in-air, non-contact object detection and ranging sensors that detect objects within an area. These sensors are not affected by the color or other visual characteristics of the detected object. Ultrasonic sensors use high frequency sound to detect and localize objects in a variety of environments.
PAGE 4
HRXL-MaxSonar® - WR/WRC™ Series Base sensor (MB7360 and MB7380) The MB7360 and MB7380 are the base model of the HRXL-MaxSonar-WR sensor line. These sensors are recommended for users unsure of which sensor to use in their application. All other sensors in this series are based off of these sensor models. The additional features are mentioned in their respective sections below.

HRXL-MaxSonar® - WR/WRC™ Series Performance Changes when Selecting a Non-Full Horn Package When selecting a SCXL-MaxSonar-WR sensor without the full horn the sensor will experience the following performance changes:      The sensor will have a wider beam shape for the first meter. The sensor may be less accurate by an additional +/- 0.5%. The sensor may have a dead zone from 0mm–500mm. The sensor may have worse performance to small or soft targets.

HRXL-MaxSonar® - WR/WRC™ Series Sensor minimum distance - No sensor dead zone (MB7360, MB7369, MB7380, and MB7389) The 5 meter sensors have a minimum reported distance of 30-cm (11.8 inches). However, the HRXL-MaxSonar-WR will report targets up to the sensor face (for the WR sensors)1 and to within 1-mm of the front sensor face (for the WRC sensors)1. For the 5 meter HRXL-MaxSonar-WR sensors, targets closer than 300-mm will typically range as 300-mm.

HRXL-MaxSonar® - WR/WRC™ Series Temperature Compensation On Board – Internal Temperature Compensation The speed of sound in air increases by about 0.6 meters per second, per degree centigrade. Because of this, each HRXL-MaxSonar-WR is equipped with an internal temperature sensor which allows the sensor to apply compensation for speed of sound changes. The actual air temperature of the path between the sensor and the target may not match the temperature measured at the sensor itself.
