MB1643 HRLV-ShortRange-EZ4 High Performance Ultrasonic Rangefinder

Features of the MB1643, HRLV-ShortRange-EZ4, include millimeter resolution, range information from 2cm to 5m, a 10Hz read rate, and various output options: pulse-width, analog voltage, and RS232.

The HRLV-ShortRange-EZ4 is the narrowest beam width sensor which is also the least sensitive to side objects offered in the HRLV-ShortRange-EZ sensor line.

The HRLV-ShortRange-EZ4 is an excellent choice when only larger objects need to be detected.

Specs:

• Resolution of 1‑mm
• 10Hz reading rate
• Internal temperature compensation
• Cost-effective solution where precision range-findings are needed
• Sensor component allows users to lower the cost of their systems without sacrificing performance
• 42kHz Ultrasonic sensor measures distance to objects
• RoHS compliant
• Read from all sensor outputs: Analog Voltage, RS232  and Pulse Width
• Virtually no sensor dead zone, large objects closer than 30 cm are typically reported as 30 cm
• Accuracy is factory-matched providing a typical accuracy of 1% or better
• Maximum range of 5000 mm (195 inches)
• Tolerates outside noise sources
• Operates from 2.5V-5.5V
• Low 3.1mA average current requirement
• Small, light weight module
• Designed for easy integration into your project or product
• Operational Temperature from -0C to +65C (+32F to +149F)
• Real-time automatic calibration (voltage, humidity, ambient noise)
• Option external temperature compensation HR‑MaxTemp
• Firmware filtering for better noise tolerance and clutter rejection
• Great starting point for users unsure of which sensor to use
