Italian Eltra Eltra linear sensor: It has the characteristics of high precision and long life and easy installation. The standard impact is from 10 (4/10) mm to 1250 mm (4ft). ELTRA's magnetic encoders have a wide range of configurations to provide precise, no connected position sensing.
The difference between incremental encoder and absolute encoder
Incremental encoder
The incremental encoder converts the displacement into a periodic electrical signal, and then converts this electrical signal into a counting pulse. The number of pulses is used to indicate the magnitude of the displacement. According to the working principle, the encoder can be divided into incremental and absolute Two types.
Features of absolute encoders _ absolute value encoder applications
The principle of absolute encoder
There are many optical channel engraved lines on the optical code disk of absolute encoder, and each engraved line is arranged in 2 lines, 4 lines, 8 lines, and 16 lines in sequence. In this way, at each position of the encoder, by reading each engraved line The opening and darkening of the line obtain a set of unique binary codes (Gray codes) from the zero power of 2 to the n-1 power of 2, which is called an n-bit absolute encoder.

Working principle of absolute encoder
The absolute rotary photoelectric encoder is shown in Figure 4-13. The absolute encoder determines the uniqueness of each position by the mechanical position. It does not need to be memorized, does not need to find a reference point, and does not need to keep counting.
Connection method of rotary encoder and counter
To connect with the counter, take H7CX (made by OMRON) as an example. H7CX input signal is divided into non-voltage input and voltage input.
No voltage input
When inputting in no-voltage mode, only NPN output signal is accepted.
Working principle and development of frequency counter
Digital frequency meter is an indispensable measuring instrument in scientific research and production fields such as computers, communication equipment, audio and video. And it has a very close relationship with many electrical parameter measurement schemes and measurement results. Therefore, the frequency measurement is more important. This article mainly introduces the working principle of the frequency meter.
Difference between incremental encoder and absolute encoder
An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission, and storage. The 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.
