Proxitron LLX series laser light barriers offer a wide range of functions and an extremely long range, which enables the detection of hot and cold objects.
When high precision and reproducibility are required, proxitron laser light barriers are the ultimate solution for detecting small objects or contours.
The Sensors can be easily adapted to a wide range of application conditions using software or teach-in. The adjustable switch-on and switch-off delay also offers a wide range of options. The optical adjustment tool simplifies installation if a large distance between the laser light barrier is required.
The robust design guarantees safe operation even in the case of vibration, and the temperature-resistant glass optics withstand radiant heat. Designs with a cooling jacket are available for higher ambient temperatures, and an alarm function signal is emitted in the event of soiling and overheating.
