L23
The L23 Optical Modular Linear Encoder provides high-precision incremental measurement across long travel distances, making it ideal for industrial automation and precision machinery. It measures lengths up to 20,000 mm and achieves accuracy up to ±3 µm per meter, while offering customization for even longer distances upon request.
In addition, the L23 offers modular reference mark options and a grating period of 20 µm, 40 µm, or 400 µm, which simplifies system integration. Furthermore, its low moving force requirements and IP64 protection with compressed air, combined with robust vibration and shock resistance, deliver consistent and reliable performance in demanding industrial environments.
