Nemicon – Standard Shaft Type Encoder 50S/NOC3

Standard Shaft Type Encoder (Outer Diameter φ50mm)

Brand : Nemicon

The Nemicon 50S / NOC3 Series is a standard shaft type incremental rotary encoder designed for high reliability motion detection in industrial automation systems. With an outer diameter of approximately 50 mm and a compact body length, the encoder provides durable construction and stable signal output for demanding machinery. Its IP65 protection rating allows it to operate in environments where dust and moisture may be present, making it suitable for factory automation equipment, motors, conveyors, and packaging machines.

The 50S / NOC3 encoder supports resolutions ranging from around 360 to 5000 pulses per revolution, allowing accurate monitoring of rotational position, speed, and direction. Multiple output options such as open collector, complementary output, and line driver are available to ensure compatibility with PLCs, motion controllers, and drive systems. With high response frequency and robust mechanical design, the encoder provides stable performance for precise industrial motion control applications.
