Role of vertical absolute encoders, precautions, detection methods and labeling methods

Absolute encoders areVertical absolute encodersand horizontal absolute encoder, absolute encoder can be used for voltage division, shunt, rectifier, etc., office decoration designers are used to adjust the sound, temperature, dimming, function adjustment, etc., the application is very wide, on theVertical absolute encodersThe vertical absolute encoder, the role of the vertical absolute encoder, the use of vertical absolute encoder attention to the place, vertical absolute encoder detection methods and vertical absolute encoder labeling methods.

The role of vertical absolute encoders

　　First, the role of voltage division: when a vertical absolute encoder and another component such as a light bulb in the circuit is in series, the current flowing through the resistor and the bulb is the same, and the resistor and the bulb of the respective voltage sum is equal to the resistor and the bulb as a whole when the overall voltage at the ends. Vertical absolute encoder plays the role of voltage divider.

　　Second, shunt/current-limiting effect: when a resistor and another component such as a light bulb in the circuit is in parallel, the resistor terminal voltage and the bulb terminal voltage is the same, and the current flowing through the resistor and the current flowing through the bulb is equal to the sum of the current flowing through the resistor and the bulb of the total current. At this point, the vertical absolute encoder plays the role of shunt/current limiting.

　　Third, impedance matching: impedance matching refers to the signal transmission process, in order to get the maximum power output of a working state, and the use of some methods to make the load impedance and the excitation source of the internal impedance of the process of mutual adaptation. And one of the methods is to change the impedance force to realize, then the vertical absolute encoder plays the role of impedance matching.

　　Fourth, the role of filtering: in the vertical absolute encoder and capacitor series composed of RC charging and discharging circuit, the use of RC between the charging and discharging of the infinite cycle, we will resistor R play a role called filtering.

Precautions for use of vertical absolute encoders

　　First, the welding must pay attention to the use of flux, should avoid the use of water-soluble flux. The use of high-frequency soldering should pay attention to the plastic parts in the absolute value encoder.

　　Avoid wiring and adding tin to cause solder flow through the circuit board, resulting in poor contact with the vertical absolute value encoder (loose lines).

　　Third, try to finish within 3 seconds, due to the maximum temperature of the soldering iron contact is lower than 270 degrees. If the time is too long or the temperature is too high, it will cause various problems such as poor contact (loose wiring) of the absolute value encoder.

Vertical Absolute Encoder Inspection Methods

　　First, the digital method: usually there are three resistors on the number XXX, the first two numbers in turn is the tenth and the digit, the last one is the number of 10 X times, the specific resistance value of this resistor is the first two numbers composed of two digits multiplied by 10 X times Ohm).

　　Second, the color ring method: This labeling method is the most common in all the resistor nominal method, the common color ring usually has four rings, here we put the gold or silver ring as the last ring, in the knowledge of the corresponding color on behalf of the corresponding number of the premise, the first three rings of the color corresponds to the corresponding number, we know the number of the digital method should be used to read the resistance value of the number of the method, the two colors in the four-color ring resistor just The two colors in the four-color ring resistor are just marking the error value, so as long as we know it, we can do it.

Vertical absolute encoder labeling method

　　First, the color-coded method: with different colors of the color ring to indicate the resistance value of the resistor and the deviation level, ordinary resistors generally have 4 rings to indicate. Waterproof encoder is a signal or data preparation is converted into a usable form of communication, transmission and storage devices, the angular displacement or linear displacement into an electrical signal, the former is called the code disk, the latter is called the code ruler. The signal output of the encoder includes sine wave, square wave, open collector, push-pull and many other forms.

　　Second, the direct labeling method: the technical performance of the resistor and the main parameters with letters or numbers directly marked on the resistor body.

　　Third, the text symbol method: the numbers, words and the two regularly combined to indicate the main parameters of the resistor.

　　Chip resistor labeling method: the first two indicate the effective number, the third indicates the effective value plus the number of zeros. Multi-turn absolute encoder if you want to measure the rotation of more than 360 degrees range, we need to use multi-turn absolute encoder. Encoder manufacturers use the principle of clock and watch gear machinery, when the center of the code disk rotation, through the gear drive another set of code disk (or multiple sets of gears, multiple sets of code disks), in the single-turn encoding on the basis of an increase in the number of laps of coding, in order to expand the encoder's measurement range, such absolute encoder is known as a multi-turn absolute encoder, which is likewise determined by the mechanical position of the encoding, the code of the unique non-repeat of each position, while the There is no need to memorize. Single-turn absolute encoder to rotate in the measurement of the optical code disk of the various engraved lines, in order to obtain a unique code, when the rotation of more than 360 degrees, the code is back to the origin, which does not comply with the principle of the absolute code is unique, so the encoder can only be used for the measurement of the rotational range of 360 degrees or less, known as the single-turn absolute encoder.
