High-Performance 4- to 20-mA Output Ultrasonic Sensor

MaxBotix’s new 4-20HR-MaxSonar-WR sensors are high-accuracy ultrasonic sensors featuring a 4- to 20-mA output. Each sensor is an affordable IP67-rated drop-in replacement for use with existing PLC/process control systems. The sensors reject outside noise sources and feature speed-of-sound temperature compensation.

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

A six-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.

The 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 0.75″ NPTS PVC pipe fittings.

Pricing starts at $199.95 each and $134.37 in 100-unit quantities.
