4-20HR-MaxSonar-WR Released

The new 4-20HR-MaxSonar-WR sensors are high accuracy ultrasonic sensors featuring a 4-20mA output. These sensors are a low cost, IP67 rated drop-in replacement for use with existing PLC/process control systems. The sensors offer superior rejection of outside noise sources and feature speed of sound temperature compensation.

The 4-20HR-MaxSonar-WR sensors provide range information from 50cm to 500 cm and have a 1.6mm resolution, an operational temperature range from -40˚C to +65˚C (-40˚F to +149˚F), real-time automatic calibration, a 200,000+ Hours MTBF, an operational voltage range from 12V to 32V and a low 20-40mA average current requirement. The sensors function well with multiple sensors in the same location and they are RoHS and CE Compliant.

A 6-pin screw terminal header is included to simplify system connections for quick installation in applications such as tank level measurement, tide/water level monitoring, solar/battery powered applications, industrial automation and outdoor vehicle detection.

These 4-20HR-MaxSonar-WR sensors (and previous IP67 MaxBotix sensors) are manufactured in a variety of packages for easy mounting in existing fittings. The sensors are available in M30x1.5, 1” BSPP, 1” NPTS and 3/4” NPTS PVC pipe fittings.

Pricing starts at $199.95 each.
