Nemicon – Heavy Duty Encoder OVF

Small Shaft Delivery Encoder (Outer Diameter φ39mm)

Brand : Nemicon

The Nemicon OVF Series is a heavy duty incremental rotary encoder designed for demanding industrial environments that require reliable and accurate motion feedback. With a robust housing diameter of approximately 39 mm and an IP65 protection rating, the encoder is built to withstand dust, vibration, and moisture commonly found in industrial machinery. The OVF series also supports shaft diameters up to 8 mm, making it suitable for larger motor shafts and heavy duty mechanical couplings used in automation equipment.

The encoder provides incremental output signals that allow precise monitoring of rotational position, speed, and direction. It supports a wide range of resolutions typically from 100 to 3600 pulses per revolution, enabling flexible integration into different motion control applications. With multiple selectable output modes and power supply options, the OVF series can easily interface with PLCs, motion controllers, and industrial drive systems for reliable feedback in manufacturing, packaging, and processing machinery.
