Functions and Operating Principle

Diffuse reflection principle: the sensor detects light reflected from an object without using a separate reflector – simple and quick for automation applications.
Adjustable detection distance: allows precise setup for specific working conditions.
Dual output (NPN + PNP): universal connection to various control systems.
High resistance to electromagnetic interference: stable operation near powerful equipment.
IP67 protection: fully resistant to dust, moisture, and mechanical impact.
Fast response time: suitable for detecting moving objects.
LED indication: real-time display of power and output status.

Applications

For home users or hobbyists: Suitable for object detection in workshops or custom automation projects.
For engineers / automation specialists: Ideal for robotics, production lines, conveyors, counting, or positioning systems.
For electricians / technicians: Easy installation due to compact housing; clear LED indicators help quickly determine status and detect faults.
