Practical guide: Setting up ultrasonic sensors correctly and commissioning them

You've found the right ultrasonic sensor and now want to integrate it optimally into your system? This guide and the following video take you step by step through commissioning and show you how to set switching points or switching windows precisely – either directly on the sensor using the Teach button or via IO-Link.

This video shows you the entire process in detail, from installation to the finished configuration.

Step by step: The key phases of commissioning

Based on the video, we've summarised the crucial steps for you:

1. Mechanical installation and electrical connection

Installation: Mount the sensor securely and ensure the correct distance to the target object (observe the blind zone). The sensor face should be aligned as perpendicular as possible to the object to be detected.
Connection: Connect the sensor to your controller or your IO-Link master using a suitable M12 connection cable. Check the pin assignment in the data sheet.

2. Setting the switching points using the Teach button

Many autosen ultrasonic sensors can be conveniently taught in directly on the device without a PC:

Teach in a switching point: Position the object at the desired switching distance. Press the Teach button for the duration specified in the data sheet to save this point.
Teach in a switching window (hysteresis): Perform teach-in at the first switching point (e.g. minimum fill level). Then move the object to the second switching point (e.g. maximum fill level) and perform the second teach operation. The sensor will now switch only within this defined window.

3. Alternative: Parameterisation via IO-Link

Sensors with an IO-Link interface offer extended options. Connect the sensor to an IO-Link master and use software (e.g. autosen.cloud) to configure measuring ranges, switching points and filter functions with exact numeric values.

4. Functional test

After setting the parameters, verify operation by moving the object several times into the sensing range and back out again. Check on your controller whether the signals are received as expected.
