Nemicon – Shaft Type with Flange Encoder OEK

Shaft Type With Flange Encoder (Outer Diameter φ58mm)

Brand : Nemicon

The Nemicon OEK Series is a shaft type incremental rotary encoder designed with a flange mounting structure for stable installation in industrial equipment. With an outer diameter of approximately 58 mm, the encoder provides durable mechanical support and accurate rotational feedback for machinery that requires reliable motion detection. Its flange design simplifies mounting and alignment, making it suitable for integration into motors, CNC machines, and automated manufacturing equipment.

The OEK encoder is categorized as a low pulse model and supports several resolution options ranging from about 20 to 360 pulses per revolution. It provides incremental output signals such as A and B phase, with optional index signal support depending on configuration. Multiple output circuit types and power supply ranges are available, allowing compatibility with PLCs, controllers, and industrial motion systems where stable signal feedback and easy installation are required.
