Main functions:
This photoelectric sensor operates on the polarized retro-reflective principle:

The emitter sends a red light beam that reflects from the special TD-09 reflector and returns to the receiver.
When an object appears between them, the beam is interrupted, and the sensor instantly sends a signal to the automation controller or device.
Thanks to the polarization filter, the model avoids false detections from shiny or metallic surfaces – essential for use on production lines, conveyors, or packaging machines.

Usage and application:

For home users: Suitable for metal detection in workshops or custom automation projects.
For engineers / automation specialists: Widely used in factories, conveyors, packaging, transport, and sorting systems, as well as robotics and CNC equipment. Suitable for detecting metal, plastic, cardboard, glass, and other opaque objects.
For electricians / technicians: Easily connects to controllers (PLC), relays, or automation systems. IP67 protection ensures reliable use in humid or dusty environments.

Pros:

Adjustable detection distance

Excellent performance with shiny or semi-transparent objects

IP67 protection – resistant to dust and moisture

360° LED indicators – clear sensor status

Cons:

Performance may decrease under strong sunlight (>10,000 lux)

Not suitable for completely transparent objects without contrast
