Main functions:

The retroreflective sensor uses a single optical unit for both light emission and reception.
The infrared beam reflects off a special reflector (TD-09), and when an object interrupts the beam, the sensor activates the output signal.
This principle allows object detection from a distance without direct contact, ensuring reliable operation even under ambient light, dust, or vapor conditions.

Applications:

For home users: Suitable for metal detection in workshops or DIY automation projects.
For engineers/automation specialists: Commonly used in factories, conveyors, packaging, transport, sorting systems, robotics, and CNC equipment. Suitable for detecting metal, plastic, cardboard, glass, or other opaque objects.
For electricians/technicians: Easily connects to PLCs, relays, or automation systems. IP67 protection ensures safe use in humid or dusty environments.

Advantages:

High accuracy and fast response

Resistant to environmental disturbances (dust, light, vibration)

IP67 protection – resistant to moisture and dirt

Suitable for industrial systems

Disadvantages:

Requires a reflector (TD-09) – additional component

Not suitable for completely transparent or mirror-like objects
