An encoder is a specialized device that is used to measure either linear, angular, or rotary motion. The ZHG12004 is one such encoder used to measure rotary motion through a shaft or wheel. It typically consists of two parts: a stationary component, as well as a rotating component called the code wheel. These two parts are connected, and as the code wheel rotates, a series of slots and holes pass over a light source and a photosensor.

Application field and working principle

The ZHG12004 is a popular optical incremental encoder, which is usually employed in various machine control systems and motor feedback control, such as precise positioning systems, motor speed regulation systems, and so on. It works through emitting light from a light source, which is then blocked or partially blocked as it passes through the code wheel slots, a disc with regular radial slits. The passing of the code wheel over the light source is then detected by a photosensor, or an array of photosensors, which convert the shadow into an electrical signal. This is then used to control various machine functions depending on the machine’s speed, acceleration, and position.

The ZHG12004 encoder is accurate and reliable and can work at relatively high speeds. It is compatible with the majority of motion control systems and has few mechanical stress parts, thus making it less prone to wear and tear. The encoder is easy to install, and in addition to its light weight and small size, it is widely used in applications requiring high performance.

Features

The ZHG12004 has various features, including:

• Small size: It is just 8mm wide and 12mm in diameter, which makes it ideal for application spaces with limited space.
• Wide operating range: It can work at high speeds up to 12000 RPM and as low as 100 RPM.
• High Accuracy: The ZHG12004 provides a high accuracy of ±12 arc minutes in a single reading, along with a fast response time.
• High reliability: It is highly reliable and designed to withstand harsh operating environments.
• Versatility: It is compatible with a wide range of motion control systems, making it suitable for a broad range of applications.

Design of the ZHG12004

The design of the ZHG12004 has been optimized for performance and reliability. The encoder is made from high-quality materials to ensure a long lifespan. The code wheel is connected to a shaft, and a single set of hall effect sensors is used to read the transition of the code wheel slots in order to accurately measure speed and angular position. The light source and photosensor are also integrated into the design to detect the code wheel’s rotation. Additional components used in the encoder’s design include a metal housing that acts as a shielding from external light, reducing any possible optical interference.

The ZHG12004 encoder is a highly accurate device with features that make it ideal for many applications where accuracy and speed are paramount. Its small size and wide compatibility make it popular in the automation and machine control market. Its reliable and robust design make it well-suited for industrial environments, while its low cost makes it attractive to customers.
