SCXL-MaxSonar-WR Series Ultrasonic Sensor Product Description
The SCXL-MaxSonar-WR/WRC sensor line includes an effective self-cleaning capability designed to reduce the impact of condensation in closed or high-moisture (dew, frost, etc.) environments. This sensor is a cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, low-cost, self-cleaning, and IP67 weather resistance rating is needed. This sensor component module allows users of other, more costly precision rangefinders to lower the cost of their systems without sacrificing performance.

The SCXL-MaxSonar-WR/WRC self-cleaning sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, with an IP67 weather resistant rating. 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 SCXL-MaxSonar-WR/WRC self-cleaning models are available in 5-meter or 10-meter models. This ultrasonic sensor 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 (MB7560 series) or TTL (MB7580 series).

Precision Ultrasonic Range Sensing
? Self-cleaning algorithm
? Reading-to-reading stability of 1-mm at 1-meter is typical
? Factory matched accuracy, typical accuracy of 1% or better
? Target size and operating voltage compensation
? Internal temperature compensation
? Optional external temperature compensation
? Determines range to largest object (MB7569 , MB7589)
? Determines range to first detectable object  (MB7560, MB7563, MB7566, MB7567, MB7580, MB7583, MB7586, MB7587)
