XL-MaxSonar®- WR/WRC™ Series
High Performance, IP67 Weather Resistant, Ultrasonic Range Finder

The XL-MaxSonar-WR and XL-MaxSonar-WRC sensor series provide users with robust range information in air. These sensors also feature high-power acoustic output along with real-time auto sensitivity adjustment for changing conditions (supply voltage sag, acoustic noise, or electrical noise), operation with supply voltage from 3V to 5.5V, object detection from 0-cm to 765-cm (select models) or 1068-cm (select models), and sonar range information from 20-cm1 out to 765- cm (select models) or 1068-cm (select models) with 1-cm resolution. Objects from 0-cm to 20-cm1 range as 20- cm1 or closer. The sensor is housed in a robust PVC housing, designed to meet the IP67 water intrusion standard, and matches standard electrical/water ¾” PVC pipe fittings. The user interface formats included are pulse-width (select models), real-time analog-voltage envelope (select models), analog voltage output, and serial output.

FEATUREs
• Real-time auto sensitivity adjustment
   and noise rejection
• High acoustic power output
• Precise narrow beam
• Object detection includes zero range
   objects
• 3V to 5.5V supply with very low
   average current draw2
• Free run operation can continually
   measure and output range information

Benefits
• Acoustic and electrical noise
   resistance
• Reliable and stable range data
• Robust, low cost IP67 standard
   sensor
• Narrow beam characteristics
• Very low power excellent for battery
   based systems
• Ranging can be triggered externally
   or internally
• Sensor reports the range reading
   directly, frees up user processor
• Easy hole mounting or mating with
   standard electrical fittings
• Filtering allows very reliable
   operation in most environments

APPLICATIONs and Uses
• Tank level measurement
• Bin level measurement
• Proximity zone detection
• Environments with acoustic and
   electrical noise
• Distance measuring
• Long range object detection
• Super high sensitivity for long range
   small object detection (MB7051 &
   MB7053)
• Industrial sensor -40°C to +65°C
   (limited operation to +85°C) 2
