SICK WLG4S-3P2232VS03 is a sensor with a lockable Teach function. This means that you can press the Teach button for 10 seconds to unlock the Teach function for 10 minutes. After 10 minutes of inactivity, the Teach function will be locked again. You can also unlock the Teach function by activating the electrical Teach input (ET) for more than 10 seconds. The Teach release will be visualized with the yellow LED flashing 3 times.

This sensor is ideal for applications where you need to be able to teach the sensor to a new position or object without having to worry about accidentally triggering the Teach function. For example, you could use this sensor in a conveyor system to teach the sensor to the position of a product that is being conveyed. This would allow the sensor to reliably detect the product and trigger an output signal when the product reaches the sensor.
