Nemicon – Standard Shaft Type Encoder 50S2

Standard Shaft Type Encoder (Outer Diameter φ50mm)

Brand : Nemicon

The Nemicon 50S2 Series is a high resolution incremental rotary encoder designed for precise motion detection in industrial automation and control systems. Featuring a 50 mm outer diameter and a solid shaft design, the encoder provides reliable mechanical coupling and stable signal output for accurate monitoring of rotational position and speed. The series also includes an IP65 protection rating, allowing the encoder to operate reliably in environments where dust and moisture may be present.

The 50S2 encoder supports very high resolution options up to 20000 pulses per revolution, making it suitable for applications that require highly accurate motion feedback. It is compatible with the 50S / NOC3 series mounting structure, allowing easier replacement or system upgrades. With multiple output circuit options and wide power supply compatibility, the encoder integrates easily with PLCs, motion controllers, and servo systems used in machine tools, servo motors, and industrial automation equipment.
