Nemicon – Modular Encoder 18M

Miniature Modular type High Resolution (Outer Diameter φ18mm)

Brand : Nemicon

The Nemicon 18M Modular Encoder is a compact incremental rotary encoder designed for precision motion detection in space constrained equipment. With an outer diameter of only 18 mm, this miniature modular encoder provides accurate rotational feedback while allowing flexible integration into motors, robotic mechanisms, and automation systems. Its modular structure separates the sensing unit and code disc, enabling engineers to integrate the encoder directly into custom assemblies while maintaining high measurement accuracy.

The encoder supports a wide resolution range from 200 to 1600 pulses per revolution, making it suitable for applications that require reliable speed, position, and direction feedback. The 18M series also provides selectable output types such as open collector and line driver, allowing compatibility with various controllers, PLCs, and motion control systems. With a lightweight design and high rotational capability, the encoder delivers stable signal output for industrial automation, robotics, and compact mechanical equipment.
