Our retro-reflective area sensor operates with the same principle as the retro-reflective sensor, except it contains several transmitters and receivers in one enclosure, with a reflector positioned opposite, forming a detection area with a consistent width and height over the relevant sensing range.
When the light beams in the detection area are interrupted by an object, the switching function is triggered.
The RLG28 retro-reflective area sensor
operates according to the reflection principle | RLG28 retro-reflective area sensor reliably detects objects of different shapes and sizes |
Apart from lower prices, the benefits compared to light grids include the reflection principle.
While the retro-reflective area sensor operates with a simple reflector, light grids consisting of a transmitter and receiver must always be wired at two ends. Retro-reflective area sensors are easier to install
