Functions and operating principle
The sensor operates on the background suppression principle, allowing accurate detection of objects regardless of background or color.
It can distinguish an object from surrounding surfaces, making it ideal for detecting light, glossy, or semi-transparent objects.
The 5-turn adjustment knob allows easy sensitivity setting, while the LED indicators help monitor sensor status and signal strength.

Applications
For home users or hobbyists: Suitable for object detection in workshops or personal automation projects.
For engineers / automation specialists: Ideal for robotics, production lines, conveyors, counting, or positioning systems.
For electricians / technicians: Compact design enables easy installation; clear LED indicators simplify diagnostics and maintenance.
