Compact Optical Sensor with Area Beam
LRL Series
 | LRL series optical sensor is new model made by HEROJE produce a line-shaped beam that is 110 mm long (distance on 100mm), specially designed for detecting objects with gaps or holes still constitutes a challenge for many other optical sensors in factory automation. Offering a simple and extremely effective standard presence detection solution for PCB(printed circuit boards), pallet cages or even bakery products. |
One-Click Calibration
One-click calibration feature simplifies operation, increases efficiency and accuracy, and enhances adaptability, providing users with a more convenient and effective experience. It is particularly suitable for the needs of modern industrial automation and intelligent manufacturing.

 |
Background Suppression
The background suppression feature allows LRL sensor to distinguish between target objects and the background, supporting background filtering. It is less affected by production line dirt, reducing downtime and maintenance caused by environmental changes, thereby improving overall production efficiency.

Reliable Detection of Various Irregular Targets
The LRL series sensors are capable of detecting objects with gaps or holes as well as irregularly shaped objects, such as PCB boards, pallet cages, bakery products, engine bearings, etc.
