Main functions:
The retro-reflective sensor uses a single optical module for both transmitting and receiving light.
The infrared beam reflects from a special reflector (TD-09), and when an object interrupts the beam between the sensor and the reflector, a signal is triggered.
This principle allows non-contact object detection from a distance, while the internal system ensures reliable performance even in the presence of ambient light, dust, or steam.

Applications:

For home users: Suitable for detecting metal in workshops or personal automation projects.

For engineers/automation specialists: Widely used in factories, conveyors, packaging, transport, sorting systems, robotics, and CNC machines. Suitable for detecting metal, plastic, cardboard, glass, or other opaque materials.

For electricians/technicians: Easily connects to PLCs, relays, or direct automation systems. The IP67 protection allows safe use in humid or dusty environments.

Pros:

High accuracy and fast response

Protection against environmental interference (dust, vibration)

IP67 protection – resistant to moisture and dirt

Suitable for industrial systems

Cons:

Requires reflector (TD-09) as an additional component

Not suitable for completely transparent or mirror-like objects
