Nemicon – Standard Shaft Type Encoder NOC-H

Standard Hollow Shaft Type Encoder (Outer Diameter φ50mm)

Brand : Nemicon

The Nemicon NOC-H Series is a standard hollow shaft incremental rotary encoder designed for reliable motion feedback in industrial automation systems. With an outer diameter of approximately 50 mm and a hollow shaft configuration, the encoder allows direct mounting onto machine or motor shafts, simplifying installation and reducing the need for additional couplings. Its compact design and versatile mounting structure make it suitable for motors, conveyors, packaging machinery, and other automated equipment that require accurate rotational detection.

The NOC-H encoder supports a wide resolution range from around 100 to 5000 pulses per revolution, enabling precise monitoring of rotational position, speed, and direction. Multiple output circuit types are available, including voltage output, open collector, push pull, and line driver, allowing compatibility with different PLCs and motion controllers. With stable signal performance and flexible electrical options, the NOC-H series provides dependable feedback for industrial motion control applications.
