Introduction

The 4-20HR-MaxSonar-WR sensor series is a high-performance, high-precision ultrasonic rangefinder that delivers high-accuracy, high-resolution ultrasonic distance detection in air. This sensor series is a cost-effective solution for automation/process control applications requiring precise ranging, low-voltage operation, space savings, low cost, and IP67-rated dust and water resistance. This sensor component enables users of other more expensive precision rangefinders to reduce their system costs without sacrificing performance. The sensor output is compatible with existing PLC equipment and is also suitable for long cable run applications. The 4-20HR-MaxSonar-WR/WRC sensor series features 1.6mm resolution, excellent rejection of external noise sources, internal speed-of-sound temperature compensation, and optional external speed-of-sound temperature compensation. Sensors are factory calibrated to provide stable and reliable distance readings. With a maximum range of 5 meters, these ultrasonic sensors can detect targets starting from 5mm, with measurements from 50cm to maximum range. Targets closer than 50cm are typically reported as 50cm.
