An Absolute Singleturn Solid Shaft Encoder is a precision absolute position encoder designed to measure the exact angular position of a rotating shaft within a single revolution. Unlike incremental devices, a rotary absolute encoder provides a unique digital output for every position of the shaft, ensuring that the precise location is always known even if power is interrupted. This makes it an essential component in modern automation systems where accurate position tracking is critical.
These encoders typically utilise several digital coding systems to determine the position of the shaft. A Gray Code encoder, binary code encoder, Binary Coded Decimal (BCD), or natural binary output may be used depending on the application requirements. Each coding system allows the industrial position encoder to transmit highly accurate position data to control systems, enabling machinery to monitor and adjust movement with exceptional precision.
An absolute singleturn solid shaft encoder is specifically designed to measure the angular position of a shaft within one full rotation. As the shaft turns, the encoder produces a digital signal that corresponds directly to the exact angle of rotation. This makes the device particularly useful in machinery where components move in a swivelling motion and require precise positioning feedback. The solid shaft design ensures reliable coupling to mechanical systems and provides durability for demanding industrial environments.
A precision position control encoder is widely used in a variety of advanced machinery and automated systems. For example, an encoder for CNC machines enables accurate positioning of cutting tools and mechanical arms, ensuring precise manufacturing operations. Similarly, these encoders are used in solar tracking systems to record the position of solar panels as they follow the movement of the sun, helping maximise energy efficiency.
Beyond CNC equipment and renewable energy systems, solid shaft encoders are commonly used in forestry vehicles, medical devices, mining drills, wind energy installations, and heavy construction equipment such as cranes. In these environments, the ability of a rotary absolute encoder to deliver precise position data improves operational control, safety, and reliability.
The encoders supplied by Greenbank are manufactured by the Italian company Italsensor, a recognised leader in the development of advanced motion control technologies. The company has collaborated with the Department of Robotics at the Polytechnic University of Turin to push the boundaries of innovation in encoder design and precise position control systems.
