MB7780 4-20SC-MaxSonar-WRI
Industrial Outdoor High Performance Self-cleaning Ultrasonic Precision Rangefinders

MB7780 4-20SC-MaxSonar-WRI Ultrasonic Rangefinder Product Description
The weather resistant 4-20SC-MaxSonar-WRI 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 is available in multiple packaging types.

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 4-20SC-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7780 features 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 weather resistance (IP67) rating is needed.

The MB7780 4-20SC-MaxSonar-WRI outputs a 20-4mA signal for PLC integration. A 20mA output signifies that the sensor is reporting the minimum reported distance of 50cm, where as a 4mA signal signifies the sensor is reporting the maximum reported distance of 500cm.

Additional Chemical Resistance 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.
