TD-02, LANBAO, reflector for retro-reflective photoelectric sensors, rectangular, 40 x 65 mm

TD-02 is a reflector made by LANBAO designed for retro-reflective photoelectric sensors. It is a passive optical element that returns the light emitted by the sensor back to its receiving optics.

This variant has the design rectangular and dimensions 40 x 65 mm. The reflector requires no supply or electrical wiring and is used as the opposite part of a retro-reflective light barrier.

How a retro-reflective light barrier with a reflector works

In a retro-reflective photoelectric sensor, the emitter and receiver are in one housing. The emitted beam hits the reflector, which returns it to the sensor. An object passing between the sensor and the reflector interrupts the light path and the sensor evaluates the change in received light.

Typical applications

Reflector TD-02 is suitable as a reflective surface for retro-reflective photoelectric sensors on conveyors, packaging lines, logistics lines, assembly machines and other equipment where the passage or presence of an object is monitored.

When designing the application, it is necessary to assess the actual working distance of the sensor, the size of the reflector, the mounting space, the properties of the detected object and the ambient conditions.

Technical specifications

Mounting and optical alignment

Mount the reflector opposite a compatible retro-reflective sensor so that its active reflective surface lies in the optical axis of the sensor. After fixing, adjust the position of the sensor and reflector so that the received signal is stable and has a sufficient operating reserve.

Keep the reflective surface clean. Dust, oil, condensation or mechanical damage can reduce the amount of returned light and reduce the operating reserve of detection.

How to choose the right reflector

When choosing, compare above all the size and shape of the reflective surface, the available mounting space, the required working distance and the sensor manufacturer's recommendation. For polarised retro-reflective sensors it is important to use a suitable retroreflective element; an ordinary shiny surface is not an equivalent substitute.

Application example

On a conveyor, the retro-reflective sensor is mounted on one side and the reflector TD-02 on the opposite side. In the normal state, the beam returns from the reflector to the sensor. As soon as a box or other object enters between them, the beam is interrupted and the control system receives information about the presence of the object.

FAQ

What is TD-02 and what is it used for?
TD-02 is a passive LANBAO reflector for retro-reflective photoelectric sensors. It returns the emitted light beam back to the receiving optics of the sensor and forms the opposite part of a retro-reflective light barrier.

Does the TD-02 reflector need electrical supply?
No. It is a passive optical element without electrical connection.

What are the dimensions of the TD-02 reflector?
The source data state the dimensions 40 x 65 mm.

How to choose the right reflector size?
A larger reflective surface usually makes optical alignment easier and can increase the operating reserve of the system. However, always follow the recommendation of the specific sensor manufacturer and the required working distance.

How to mount the reflector correctly?
Place it opposite the retro-reflective sensor in the optical axis and carry out precise adjustment after mechanical fixing. After mounting, verify stable switching of the sensor across the entire working range of the application.

Can the reflector be replaced by an ordinary shiny surface?
Not recommended. A retroreflector is designed to return light towards the sensor; an ordinary shiny surface may reflect light in another direction and cause unreliable detection.

What does the achievable working distance depend on?
On the specific retro-reflective sensor, the size and properties of the reflector, the accuracy of adjustment, contamination of the optics and the ambient conditions.

How to maintain the reflector?
Keep the reflective surface clean and free of mechanical damage. Dust, oil, condensation or scratches can reduce the amount of returned light.

Is this reflector suitable for a polarised retro-reflective sensor?
Compatibility must be verified according to the specific sensor type. For polarised retro-reflective sensors, use the reflector recommended by the manufacturer of the sensor.

Where can I find compatible retro-reflective photoelectric sensors?
More variants are in the category retro-reflective light barriers with reflector and in the overview of photoelectric sensors.
