The LK18B absolute optical linear encoder delivers high-precision absolute position measurement for long-travel CNC machines, semiconductor equipment, robotics, and industrial automation systems. Designed for applications requiring extended measuring lengths, it combines micron-level accuracy, high-speed performance, and reliable absolute feedback to maximize machine productivity.
Unlike incremental encoders, the LK18B provides the exact position immediately after power-up, eliminating homing procedures and reducing downtime. In addition, it supports SSI, BiSS-C, and FANUC α/αi serial interfaces, making integration straightforward with CNC controllers, PLCs, and advanced motion control systems. An optional 1 Vpp incremental output is also available for applications that require both absolute and incremental feedback.
The LK18B measures lengths up to 3,240 mm with an accuracy of ±5 µm. Furthermore, it supports travel speeds up to 2 m/s, accelerations up to 30 m/s², and measuring steps as fine as 0.05 µm, ensuring smooth and precise positioning even in high-performance machinery.
Its rugged closed-type construction protects the optical scale from contaminants, while IP54 protection comes standard and increases to IP64 with compressed air. Multiple connector, cable, and interface options also allow engineers to configure the encoder for a wide range of industrial applications.
