Description
The SICK LL3-TB01 is a reliable plastic fiber optic sensor designed for use with compatible fiber optic amplifiers such as the WLL and GLL series. Engineered for accurate object detection, it operates on a through-beam principle, consisting of a transmitter and receiver pair for stable and precise sensing.
With an M4 threaded tip, the LL3-TB01 allows for easy installation in compact or confined spaces, making it ideal for applications requiring precise positioning and long sensing distances. It offers a sensing range of up to approximately 0.7 meters, depending on the amplifier used, ensuring flexibility across various industrial processes.
Constructed from durable plastic fiber (PMMA) with a protective jacket and stainless-steel sensing head, the sensor is built to withstand demanding industrial environments. Its flexible fiber design and long cable length (typically around 2 meters) enable easy routing and installation in tight or complex machine layouts.
The LL3-TB01 is commonly used in packaging machines, material handling systems, and automation lines where reliable object detection and space-saving sensor solutions are required. It serves as a direct replacement for older models such as LLK 2-M4GA02.
