MB7480 4-20HR-MaxSonar-WRI
High Performance Ultrasonic Precision Rangefinder

MB7480 4-20HR-MaxSonar-WRI Ultrasonic Rangefinder Product Description
The weather resistant 4-20HR-MaxSonar-WR is a rugged, ultrasonic sensor component module that features the industry standard 4-20mA analog current interface. This outdoor sensor provides very short- to long- distance detection and ranging in a compact, robust PVC housing. This ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4-inch PVC pipe fittings.

High-output, acoustic power, combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms results in virtually noise free distance readings. This holds true even in the presence of many of the various acoustic or electrical noise sources. The 4-20HR-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7480 4-20HR-MaxSonar-WR sensor has an inverted 4-20mA signal where 20mA signifies that the sensor is reporting the minimum reported distance and 4mA signifies the maximum reported distance for the sensor.

MB7360 is the non 4-20mA version of this sensor line.
MB7389 is the most likely version of this sensor.

Models with additional chemical resistance are available

The F-Option (IP-68) design modification provides our weather resistant sensors with extra protection against corrosive chemical environments. Ask for the F-Option (IP-68) when ordering.
