[Rare dry goods] I heard that you don’t understand the principle, classification, single-turn and multi-turn encoders The old engineer tells you! Recently, there are many friends, let me introduce what is the high circle and single circle of the encoder. We have introduced the servo and encoder before. Today, the editor of okplazas.com will give you a general introduction to the principle and classification of the encoder. Wait for some knowledge that you don't understand, and hope to study it carefully and digest it!

The difference between incremental encoder and absolute encoder 1. Classification of encoders According to the detection principle, the encoder can be divided into optical, magnetic, inductive and capacitive. According to its scale method and signal output form, it can be divided into three types: incremental, absolute and hybrid.

Dry goods encoder principle, line number, resolution concept, and encoder wiring method Encoders are very common in engineering applications, such as the use of servo motors for positioning control, etc., and encoders play a decisive role in them. Today I will analyze what an encoder is, and the classification and how of the encoder. application.

【Industrial knowledge】Basic knowledge of servo 1. What is servo? Why use a servo? Servo system definition: A control system that realizes the output variable accurately follows or reproduces the input variable. The requirements for motion control are getting higher and higher, and servo control comes into being.

How many pulses per revolution of the 500-line photoelectric encoder？ The so-called number of lines is the number of pulses output per revolution. They can be said to be different names for the same thing. For example, a 500-line encoder can output 500 A (or B) pulses per revolution.

How the encoder works 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.

How to distinguish the number of lines of the photoelectric encoder？ Encoders are divided into two categories: incremental and absolute. Their so-called line numbers all indicate their resolution (resolution). The resolution of an incremental encoder is expressed by the number of pulses output per revolution, ppr (pulse per revolotion) such as 2000 ppr, 8192ppr The resolution of an absolute encoder is expressed in bits, bit (binary digits). Such as 17bit, 20bit

How to select the rotary encoder？ Three parameters should be paid attention to in the selection of rotary encoder: 1. Mechanical installation dimensions, including positioning stop, shaft diameter, installation hole position; cable outlet method; installation space volume; whether the working environment protection level meets the requirements.

Is there an explosion-proof encoder for oil drum equipment Requires explosion-proof ATEX, strong impact resistance and harsh environment Our company mainly focuses on petroleum explosion-proof encoders. According to your description: I recommend Efortron encoders (M6C-4S1HX51ZTZ00), explosion-proof ATEX certification, impact resistance and other harsh environments.

The difference between industrial cameras and ordinary cameras The difference between industrial cameras and ordinary cameras: 1. The performance of the industrial camera is stable, reliable and easy to install. The camera has a compact and sturdy structure and is not easy to damage. It can work in a long time and can be used in a poor environment. Normal digital cameras cannot do this. For example: letting a civilian digital camera work 24 hours a day or working for several days will definitely be unbearable.
