AK19 single-turn absolute optical encoder, an absolute position encoder for industrial automation.

AK19 absolute optical rotary encoder

The AK19 absolute optical rotary encoder provides high-precision position feedback in a compact 19 mm housing, making it ideal for applications where installation space is limited but accuracy cannot be compromised. Using advanced optical sensing technology, the encoder delivers reliable single-turn absolute measurement with resolution up to 20 bits (1,048,576 positions per revolution).

Designed for precision motion control systems, the AK19 supports SSI and BiSS-C communication interfaces, allowing seamless integration with industrial controllers, drives, and automation equipment. In addition, it offers binary or Gray output coding for SSI versions, providing flexibility for different system requirements.

The encoder is available in both solid shaft and blind hollow shaft configurations, with multiple shaft diameter options and flexible coupling solutions. As a result, engineers can easily adapt the AK19 to a wide range of mechanical designs and compact applications.

Despite its miniature size, the AK19 delivers excellent performance in demanding environments. It supports speeds up to 10,000 rpm, provides system accuracy of ±75 arc seconds, and offers an extended temperature option from -40°C to +85°C for applications exposed to harsh conditions.
