The LK24 Optical Absolute Linear Encoder delivers high-precision absolute position feedback for industrial automation and precision motion control applications. It measures lengths up to 3,240 mm and achieves accuracy up to ±1 µm per meter, depending on the customer-specified measuring length.
The LK24 supports SSI or BiSS serial interfaces and can include an optional 1 Vpp incremental track for versatile control system integration. Its low moving force, robust construction, and IP54/IP64 protection ensure reliable performance under harsh industrial conditions, including vibration, shock, and variable humidity.
