The Accuracy Of The Bus Type Encoder

An encoder is a device that converts angular or linear displacements into electrical signals. The former is called a code plate, which is called a yardstick. According to the readout mode, the encoder can be divided into two types: contact type and non-contact type. Contact with brush output, brush contact with the conductive zone or insulation to indicate the status of the code is "1" or "0"; the non-contact receiving sensitive element is a photosensitive element or a magnetic sensitive element, which uses a photosensitive element to indicate whether the state of the code is "1" or "0".Bus Type Encoder

The accuracy of the incremental photoelectric encoder is completely unrelated to the resolution, which is two different concepts. Precision is a measure of the ability to determine the position of any pulse relative to another pulse within the range of the selected resolution. Precision is usually expressed in terms of angle, angle, or angular seconds. The accuracy of encoder is related to the manufacturing accuracy of the transmission gap, the mechanical rotation of the code plate, and the installation technology.Bus Type Encoder

The resolution and accuracy of encoders are not necessarily equal, and the accuracy is determined by various factors, such as engraving line, machine concentricity, reading response speed and temperature characteristic. If an encoder is used for high resolution by dividing the sine wave, its accuracy is not improved, and the subdivision improves the resolution only. Before subdividing the precision of the line is how much, subdivision of the precision or how much, so some high-resolution encoder precision depends on how many lines before the subdivision.Bus Type Encoder

Standard cable fittings are made of nickel-plated brass. "Such designs allow complex encoder types such as the absolute encoder with a bus cover and the requirement to protect the inside of the encoder, such as dip switches." The "59" type includes a deep drawing stainless steel shell and is connected with a stainless steel flange. Standard cable accessories are made of PVC. "This design is usually not too expensive (provides the encoder type that reduces some requirements): An incremental encoder with a cable connector, an absolute encoder with a cable connector, and a sealed enclosure (such as a parallel lap, SSI, or Biss).Bus Type Encoder
