Re: Banner Ultrasonic Sensor Q18 NPN programming issue
The sensor you've specified is a simple on/off switch. It doesn't provide any information about how far away what it's sensing is. All it tells you is whether or not something is being sensed within its calibrated range of distances. Read it as a DIO input, as if it were a limit switch, giving you a true/false value.
