Nemicon – Small Shaft Encoder 38S

Small Shaft type Encoder (Outer Diameter φ38mm)

Brand : Nemicon

The Nemicon 38S Series is a small shaft incremental rotary encoder designed for accurate motion feedback in industrial automation and compact machinery. With an outer diameter of 38 mm, it provides reliable position, speed, and direction detection while maintaining a compact footprint suitable for motor assemblies, conveyors, and automated equipment. Its solid shaft design ensures stable mechanical coupling, enabling consistent signal output even under demanding operating conditions.

The 38S encoder supports a range of resolutions from 100 to 5000 pulses per revolution, offering flexibility for applications that require different levels of precision. It provides A, B, and Z phase output signals and selectable output types including open collector and line driver, making it compatible with PLCs, controllers, and drive systems. With high response frequency and robust design, the encoder delivers stable and reliable feedback for precision motion control applications.
