Functions and Operating Principle

Diffuse reflection technology – detects objects by reflecting light without a reflector.

Adjustable sensing distance – easily set with a single button press.

NO/NC mode switching – performed by a longer press of the same button.

Resistant to ambient light – reliable even under direct sunlight or lamp illumination.

Compact square housing – ideal for various system integrations.

LED indicators – provide real-time signal strength and status feedback.

Usage and Application

For home users or hobbyists: Suitable for object detection in workshops or DIY automation projects.
For engineers / automation specialists: Ideal for robotics, conveyors, packaging, and sorting systems requiring precise, fast, and reliable detection.
For electricians / technicians: Easy to install due to compact design; clear LED indicators simplify troubleshooting and status checks.
