Eltra encoders are devices that encode signals (such as bitstreams) or data, converting them into a signal form that can be used for communication, transmission, and storage. Encoders convert angular or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to their working principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, and then convert these electrical signals into counting pulses, using the number of pulses to represent the magnitude of the displacement. Each position of an absolute encoder corresponds to a specific digital code; therefore, its reading depends only on the starting and ending positions of the measurement, and is independent of the intermediate process.

Advantages of Eltra encoders: Small size, high precision, high inherent resolution, non-contact and wear-free operation; the same type can detect both angular displacement and linear displacement with the aid of a mechanical conversion device; multi-turn photoelectric absolute encoders can detect linear displacement over a considerable range (e.g., 25-bit multi-turn). Long lifespan, flexible installation, diverse interface options, and reasonable price. Mature technology, widely used both domestically and internationally for many years.

Disadvantages of Eltra encoders: Precision but requires higher protection standards for outdoor and harsh environments; linear displacement measurement relies on mechanical conversion, necessitating the elimination of errors caused by mechanical backlash; difficulty in overcoming slippage when detecting objects moving on tracks.

Electronic Magnetic Grating Absolute Encoder (Folded)

After generating electrical signals, Eltra encoders are processed by CNC (Computer Numerical Control) systems, PLCs, and control systems. These sensors are mainly used in machine tools, material processing, motor feedback systems, and measurement and control equipment. In ELTRA encoders, angular displacement conversion utilizes photoelectric scanning principles. The reading system is based on the rotation of a radial indexing plate, which consists of alternating transparent and opaque windows. This system uses a single infrared light source for vertical illumination, projecting the image on the disc onto the surface of a receiver covered with a grating called a collimator, which has the same window as the optical disc. The receiver's function is to sense the light changes caused by the disc's rotation and convert these changes into corresponding electrical changes. Generally, the rotary encoder also provides a speed signal, which is fed back to the frequency converter to adjust its output data. Fault symptoms: 1. When the rotary encoder is faulty (no output), the frequency converter cannot function properly, running very slowly, and after a while, it will activate protection, displaying "PG disconnected"... Only a combined action will work. To raise the electrical signal to a higher level and generate a square wave pulse without any interference, electronic circuitry is required. The connection method between the encoder PG and the vector frequency converter must correspond to the encoder PG model. Generally, encoder PG models are divided into three types: differential output, open collector output, and push-pull output. The signal transmission method must take into account the inverter PG card interface; therefore, selecting the appropriate PG card model or setting it correctly is crucial.
