Type : Voltage Regulator Origin : China Condition : New

Product Introduction: 1.Operating Voltage: 5V 2.Pulse Number for One Circle: 20 3.Rotary encoder can count the output pulse times by rotating positively and negatively. This counting method has no limitation, it can reset and come back to the  initial status if matching with the key on the encoder (that is to say it will count from 0) 4.Operating Principle: Incremental encoder is a kind of rotary sensor which transforms the rotation displacement into a series of digital pulse signal. These pulses are used to control angular displacement. In Eltra encoder, the transformation of angular displacement adopts photoelectric scaning principle. The reading system is based on the radial dividing plate's rotation of alternative light window and non-light window, and it will be exposed to infrared light source at the same time. The light will reflect the picture of plate on the surface of receiver. The receiver is covered by a diffraction grating, and it has the same window width with the plate. The operation of receiver is to detect the change of light plate rotation, then transform the light change into electric change. Increase the low level signal into high level and generate square pulse without any interference. This process needs circuit to deal with. The reading system usually adopts differential method, that is compare two different signals who have the same waveform bu the phase difference is 180 degree so as to improve the output signal quality and stability. Reading is formed on the basis of the difference between two signals, so it eliminates the interference.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
