MB7589 SCXL-MaxSonar-WRMT

Self Cleaning Precision Ultrasonic Rangefinder

Product Description

The weather resistant SCXL-MaxSonar-WR self‑cleaning sensor is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.

The MB7589 SCXL-MaxSonar-WRMT features a self-cleaning transducer to remove condensation and ice buildup when operating in cold conditions. The MB7589 SCXL-MaxSonar-WRMT self‑cleaning sensor is equipped with filtering firmware that is designed to ignore smaller targets and noise, and still report the range to the target that reflects the largest ultrasonic signal. (The sensor will also reject periodic noise, even noise that has a higher amplitude than the acoustic return from the target.) This gives users the flexibility to consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view, the SCXL-MaxSonar-WRMT self‑cleaning sensor will switch to the target that gives the next largest detectable return.

The Most-Likely filter is designed to report the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, preference is given to the closest target.

MB7569 is the RS232 version of this sensor.

Models with additional chemical resistance are available

The F-Option (IP68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP68) when ordering.
