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 1.5-meter, 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 (MB736X/MB7375) or TTL (MB738X/MB7395). Factory calibration is standard. *For select sensors this distance is 50-cm, refer to pages 4 and 5.

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. Ultrasonic sensors measure the time of flight for sound that has been transmitted to and reflected back from nearby objects. Based upon the time of flight, the sensor outputs a range reading....
