Rockwell Automation Bulletin 873P Ultrasonic Sensors
Bulletin 873P ultrasonic sensors have a wide range of operating voltages and setpoints, and output functions are selected via pushbutton and protected by a lockout feature to prevent tampering or inadvertent reprogramming. Multiple status LEDs assist setup and troubleshooting. Select models have synchronization to prevent crosstalk in multiple sensor installations. They're IP67-rated, come in 18-mm and 30-mm-diameter models with analog, digital and combination output configurations, and have sensing ranges from 400 mm to 3.5 m.
