Optex FA TOF-L450DN Distance Sensor is a laser optical distance sensor using TOF (Time of Flight) technology, designed to detect objects at long distances with high stability. Thanks to the principle of measuring the transmission and reflection time of the laser beam, the sensor is virtually unaffected by the color, gloss, or tilt angle of the object, making it suitable for various applications in industrial automation.

- Detecting black or low-reflectivity objects.
- Position control in packaging machines, assembly machines, and automated logistics systems.
User Guide
- Install the sensor securely, directing the laser beam perpendicular to the detection area for maximum accuracy.
- Supply 10–30V DC power with correct polarity according to the wiring diagram.
- Adjust the distance using the integrated potentiometer if necessary.
- Avoid dust or grease on the lens surface.
- Do not obstruct the laser beam during operation.
- Periodically check the status indicator lights to ensure stable signals.
Notes on Usage
- Actual detection range depends on the object's size, color, and reflectivity.
- Do not stare directly into the laser beam for extended periods, even though the product is Laser Class 1.
- Avoid installation near strong vibration sources or temperatures exceeding the allowed limits.
- Use shielded signal cables when installing near inverters or high-power motors to ensure stable signals.
The Optex FA TOF-L450DN Distance Sensor is a high-performance laser distance sensor, notable for its ability to detect objects up to 4.5 m, fast response speed, compact design, and stable operation even with objects of varying colors or reflectivity.
