The document describes the SMAG absolute magnetic sensor series for measuring linear positions. Key features include absolute measurement without needing a home or reference position, resolutions up to 5 μm, operating temperatures from -25°C to 85°C, and IP67 protection. The sensor provides position measurements via an SSI interface and has a system accuracy of 50 μm or better depending on the model.
