How ELTRA encoders work

As a first-class Italian brand, ELTRA encoders are widely acclaimed in the industry for their excellent quality. Iltra encoders-Italian original

The ELTRA encoder consists of a photoelectric code disc with a shaft in the center, on which there are circular and dark engraved lines, and read by photoelectric transmitter and receiver devices. Obtain four sets of sine wave signals and combine them into A, B, C, D, each sine wave has a phase difference of 90 degrees (relative to a cycle of 360 degrees),

The C and D signals are reversed and superimposed on the A and B phases to enhance the stable signal; in addition, a Z-phase pulse is output every revolution to represent the zero reference position.

How ELTRA encoders work

The ELTRA encoder (encoder) compiles and converts signals (such as bit stream) or data into data that can be used for communication, transmission and storage

Signal form equipment. The ELTRA encoder converts angular displacement or linear displacement into electrical signals. The former is called a code wheel and the latter is called a code ruler.

According to the reading method, ELTRA encoders can be divided into contact type and non-contact type; according to the working principle, ELTRA encoders can be divided into incremental type

And absolute type. The incremental ELTRA encoder converts the displacement into a periodic electrical signal, and then converts this electrical signal into a counting pulse.

Use the number of pulses to indicate the magnitude of the displacement. Each position of the absolute ELTRA encoder corresponds to a certain digital code, so its indication

It is only related to the start and end positions of the measurement, and has nothing to do with the middle process of the measurement.

ELTRA encoder working principle ELTRA (encoder) is a device that compiles and converts signals (such as bit stream) or data into signal forms that can be used for communication, transmission and storage.

ELTRA converts angular displacement or linear displacement into electrical signals. The former is called a code wheel and the latter is called a yardstick. According to the reading method, ELTRA can be divided into contact type

According to the working principle, ELTRA can be divided into two types: incremental and absolute. Incremental ELTRA converts displacement into periodic electrical signals

, And then convert this electrical signal into counting pulses, and use the number of pulses to indicate the magnitude of the displacement. Each position of the absolute ELTRA corresponds to a certain

Digital code, so its indication is only related to the start and end positions of the measurement, and has nothing to do with the middle process of the measurement.
