Advantages and disadvantages of several common absolute encoders such as synthetic binary encoders

2021-02-19

Absolute value encoder is a common component, today to introduce the market commonly used several kinds of absolute value encoder, and the advantages and disadvantages of these absolute value encoder. First, the synthetic binary encoder synthetic binary encoder resistance body is made of carbon film, graphite, quartz powder and organic powder composite and so on into a kind of suspension, coated in vitreous enamel fiber plate or adhesive paper made. The production process is simple, is currently the most widely used absolute encoder. Advantages of synthetic binary encoder: wide range of resistance, high resolution, can be made into a variety of types of absolute value encoder, long life, low price, more models. Disadvantages: power is not too high, high temperature resistance, moisture resistance is poor, low resistance absolute value encoder is not easy to make. Second, the organic solid core absolute encoder organic solid core absolute encoder is a new type of absolute encoder, it is the method of heating plastic pressure, the organic resistive powder pressed in the insulator groove (meaning: the surface of the object on the concave...).

2021-02-19

Absolute encoder has vertical absolute encoder and 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 the vertical absolute encoder, detailed to introduce you to vertical absolute encoder, vertical absolute encoder to use the attention of the place, vertical absolute encoder, the detection method and the labeling method of vertical absolute encoder. Absolute encoder detection methods and vertical absolute encoder labeling methods. Vertical absolute encoder role A, 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 two ends. At this time, the vertical absolute encoder plays the role of voltage division. 　　Second, shunt/current limiting effect: when a resistor and another component such as lamp...

Absolute Encoder Replacement Precautions

2021-02-18

Some friends may be on the existing absolute value encoder supplier's quality or with the price can not meet the company's requirements and need to replace the absolute value encoder and absolute value encoder manufacturers, then, in the replacement of the original absolute value encoder need to pay attention to the following things: First, the shape of the fused absolute value encoder is very similar to the ordinary absolute value encoder, the absolute value of this absolute value encoder is best not to be with the ordinary absolute value encoder This kind of absolute encoder is better not to be replaced with ordinary absolute encoder. 　　Second, the nominal resistance value of the same case, the power (refers to the amount of work done by the object in a unit of time) can replace the power of the small, but the installation space should be enough to install the new resistor. Binary Encoder It can represent two states, on and off. This state can be realized by the height of the potential. Computers are made up of various electronic components. One of the important components is the semiconductor i.e. the familiar diode, transistor etc. A semiconductor can transmit and process by its switching state...

Absolute encoder noise how to repair

2021-02-18

　Household appliances in the absolute value encoder due to frequent use (such as recorders in the volume of the absolute value encoder is often repeated spinning), the use of a period of time is prone to failure. Absolute value encoder failure is relatively easy to produce in the machine on the performance, such as rotating the absolute value encoder noise, sound when big and small, power switch failure, etc., then the need for absolute value encoder maintenance and repair. 　　Carbon film and synthetic binary encoder application after a period of time is most likely to fail is noisy (especially non-sealed absolute value encoder with switch), the main reason is that the contact reed and the lead terminal reed between oil stains and dirt, or resistance film is worn (parts failure of a basic type) so that the contact resistance is not stable (explanation: solid stability; no change). Rope displacement sensor in accordance with the readout encoder can be divided into contact and non-contact two kinds. Contact type using brush output, a brush contact conductive area or insulated area to...

Binary Encoder Characteristics and Principles

2021-02-18

A binary encoder is made by applying a carbon film to a horseshoe-shaped sheet of paper and plastic. Absolute encoder manufacturers determine the code by the mechanical position, it does not need to memorize, no need to find a reference point, and do not have to count all the time, when you need to know the position, when to read its position. In this way, the anti-interference characteristics of the encoder, the reliability of the data is greatly improved. The relationship between its resistance change and the position of the intermediate contact is linear, logarithmic and exponential. There are several kinds of binary encoders, including large, small and miniature ones, and some of them are used together with switches to form absolute value encoders with switches. Today we will introduce you to the principle of binary encoders, the characteristics of binary encoders, and the areas of application of binary encoders. Binary Encoder Principle The binary encoder has the same three pins as a normal absolute encoder, but inside the encoder there are two metal static tabs of different lengths connected to two of the pins, and a one-week metal moving tab with teeth connected to the third pin....

Method of eliminating absolute encoder voltage variations in circuits

2021-02-18

Eliminating absolute encoder voltage variations, a problem expected with this design will be the generation of bias: the 3% error may cause the voltage to vary between 3V and 4.5V. Each position of an incremental encoder corresponds to a defined digital code, so that its indicated value is only related to the start and end positions of the measurement and not to the intermediate processes of the measurement. Basic calculations can be performed. The digital absolute encoder is 50kΩ (25% tolerance), R1 is 16.5K , R2 is 100K . The absolute value encoder end-to-end resistor 25% tolerance is the largest source of error in the design. 　　Now consider the same calculation with different tap resistors, if the absolute value encoder is 37.5kΩ the top voltage is 4.46V and the low side is 3.25V; if the absolute value encoder is 62.5kΩ the top voltage is 4.54V and the low side voltage is 2.7...
