MB7460 4-20HR-MaxSonar-WR MaxBotix Ultrasonic Sensor MaxBotix

MB7460 4-20HR-MaxSonar-WR MaxBotix Ultrasonic Sensor

Ranges from 500mm to 5000mm with 7.5Hz read rate. 4mA minimum range and 20mA maximum range. Reports range to the closest target.

The MB7460 weather resistant 4-20HR‑MaxSonar‑WR is a rugged, ultrasonic sensor component module that features the industry standard 4-20mA analogue 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.

Models with additional chemical resistance are available

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