Nemicon – Incremental Encoder 7S

Miniature type High Resolution (Outer Diameter φ7mm)

Brand : Nemicon

The Nemicon 7S Series is an ultra-miniature incremental rotary encoder designed for precision motion sensing in compact equipment. With an outer diameter of only 7.2 mm and a height of 10.5 mm, the encoder is ideal for installations where space is extremely limited. It provides accurate rotational feedback by generating incremental pulse signals that represent shaft movement, enabling precise position and speed measurement for motors and mechanical systems.

The encoder outputs standard A, B, and Z phase signals, which are commonly used in motion control systems for direction detection and indexing. The 7S Series supports multiple resolution options ranging from 100 to 400 pulses per revolution, allowing flexibility for different precision requirements. Its compact construction and high reliability make it suitable for applications such as robotics, small motors, inspection equipment, semiconductor machinery, and medical devices.
