High – Precision Incremental Encoder & Rotary Encoder

A rotary encoder is a speed and displacement sensor integrating optoelectronic and mechanical technologies. It can change the rotational movement into an electrical signal. This allows for the detection of position and speed. According to the working principle, it can be divided into photoelectric, magnetoelectric, and contact brush types. Based on the encoding disk engraving method, there are incremental and absolute types. The incremental type changes displacement into regular electrical signals. These signals turn into counting pulses. The number of pulses shows how much displacement there is. For the absolute type, each position matches a specific digital code. The indication value only relates to the starting and ending positions.

It has many technical features. These include the number of pulses per revolution, which can range from dozens to thousands. It also has a supply voltage and different output circuit modes. These modes include voltage output, line driver output, and complementary code output. The resolution is the number of light or dark lines engraved per 360-degree rotation. This typically ranges from 5 to 10,000 lines. It has many features. For example, it can rotate 360° in some cases. It also has a top-finger adjustment function and a quick push-button switch. It also has benefits like a small size, good sealing, and high reliability. This allows it to work well in many different environments.

Rotary encoders are widely used. In industrial automation, they measure angles, positions, speeds, and angular velocities. This gives important data for precise equipment control. In the automotive industry, these technologies apply to car audio, air conditioning, navigation, and other devices. They help with functions like volume adjustment and temperature control. In household appliances and other electronic devices, they are often used to improve control. This makes operation easier and more stable.
