Question

How much does wind affect Ultrasonic Sensor E4PA?

Answer



The Ultrasonic Switch uses air as the translation medium, so it is easily affected by wind. Care must be taken when using this Sensor but the E4PA is the least affected by wind out of all the OMRON Ultrasonic Sensors.

For example, wind produced by a 50-cm industrial fan at the highest level will hardly change the analog output.
