MaxBotix MB7334 HRXL-MaxSonar-WRS3

Features of the weather resistant MB7334, HRXL-MaxSonar-WRS3, include millimeter resolution, short to long distance detection, range information from 500mm to 5000mm for the nearest detectable target, heightened sensitivity over our standard sensors, a 6Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.

The MB7334 from the HRXL-MaxSonar-WRS line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing which meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.

The HRXL-MaxSonar-WRS sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7334 has an internal filter that will reset to targets that are considered valid outside of a 2% distance to target window. This makes the sensor ideal for targets that occasionally move rapidly. The sensor accurately applies temperature compensation to every reading, using either the integrated temperature sensor or the optional external temperature sensor, HR-MaxTemp.

In addition, the MB7334 offers virtually noise free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.

Variations on this sensor model

MB7344 is the TTL 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.
