Nemicon – Small Shaft Encoder 38SG

Small Shaft Delivery Encoder (Outer Diameter φ38mm)

Brand : Nemicon

The Nemicon 38SG Series is a small shaft incremental rotary encoder designed for robust motion feedback in industrial automation and precision systems. With an outer diameter of 38 mm and a solid shaft configuration, the encoder offers accurate position, speed, and direction detection while maintaining ease of integration into motors, conveyors, packaging machines, and automated equipment. Its mechanical structure is engineered for durability and stable signal performance in continuous operation environments.

The 38SG encoder supports a wide range of resolution options, providing flexibility to meet various motion control requirements. It offers standard incremental output signals (A, B, Z phases) and selectable output driver types such as open collector or line driver, making it compatible with PLCs, motion controllers, and drive systems. With high response frequency capability and reliable operation at elevated rotational speeds, this series delivers dependable feedback for demanding industrial applications.
