The sensor includes linear encoder and rotary encoder, which is used for the position measurement of speed, displacement and angle. Yuheng optics can provide rotary encoders based on optical, magnetic and gear principles, linear encoders based on optical principles and supporting products.
Multi turn absolute encoder. The encoder manufacturer uses the principle of clock gear mechanism. When the central code plate rotates, another group of code plates (or multiple sets of gears, multiple groups of code disks) are driven through the gear, and the number of turns is added on the basis of single cycle coding to expand the measurement range of the encoder. Such an absolute encoder is called a multi turn absolute encoder, which is also determined by the mechanical position, Each...
The rotary incremental encoder outputs pulses when rotating, and the position is known by the counting device. When the encoder does not move or the power is off, the internal memory of the counting device is used to remember the position. In this way, when the power is cut off, the encoder cannot move in any way. When the power is called to work, the encoder can not lose the pulse due to interference during the output pulse process. Otherwise, the zero point memorized by the counting device...
Grating rotary encoder controller Absolute rotary encoder Installation of low speed end: it is installed after the reduction gear, such as the shaft end of the winding wire rope drum or the shaft end of the last reduction gear. This method has no gear to return the clearance, and the measurement is more direct and accurate. This method generally measures long-distance positioning, such as positioning of various lifting equipment and feeding trolley.
The main performance requirements of encoder are: high precision, high sensitivity, reliable work, good stability, strong anti-interference ability, good dynamic characteristics, simple structure and low cost. The main items to be checked include: appearance; starting moment of main shaft; allowable speed; allowable axle load (axial and radial); inertia moment; vibration resistance; shock resistance; high temperature resistance; anti-interference ability; power voltage adaptability; current...
The absolute encoder outputs multi-bit digital code (gray code or pure binary code), and the parallel output means that there are many high and low level outputs on the interface to represent digital 1 or 0. For the absolute encoder with low number of bits, the digital code is generally output directly in this form, which can directly enter the I/O interface of PLC or upper computer, with immediate output and simple connection.
In practice, the faults caused by rotary encoder are not a few, and it is quite troublesome to check. Sometimes, although it has been checked, it is still not reassuring. Therefore, I would like to introduce a simple method to confirm the rotary coding fault. From the schematic diagram of the drive and regulation system, it can be clearly seen that it is because of the rotary coding that the microcomputer inverter motor is between. If there is a problem with the rotary encoder, the abnormal...
An encoder is a device that compiles signals (such as bit streams) or data and converts them into signal forms that can be used for communication, transmission and storage.Encoder converts angular displacement or linear displacement into electrical signals, the former is called code wheel and the latter is called code scale.
The main working principle of the pair encoder is photoelectric conversion, but its output is digital quantity. There are several concentric code channels on the code disk of the absolute encoder. Each code channel is composed of transparent and opaque sector sections. The number of code channels is the binary number of the code disk where it is located. The light source and photosensitive element are located on both sides of the code plate. The different position of the code plate will lead to...
Encoder manufacturers use the principle of clock gear machinery. When the central encoder rotates, another set of encoder (or multiple sets of gears, multiple sets of encoder) is driven by gears, and the number of turns is added on the basis of single-turn encoding to expand the measuring range of the encoder. Such an absolute encoder is called a multi-turn absolute encoder, which is also encoded by mechanical position, and the encoding of each position is unique and not repeated, without...
Rotate the single-turn absolute encoder to measure each scribe line of the optical code disc during rotation, so as to obtain the unique code. When the rotation exceeds 360 degrees, the code returns to the original point, which is inconsistent with the unique principle of absolute code. Such encoder can only be used for measurement within the rotation range of 360 degrees, which is called single-turn absolute encoder. If the measurement rotation exceeds 360 degrees, a multi-turn absolute...
The uniqueness of each position is determined by the mechanical position of the absolute encoder. It needs no memory, no reference point, and no constant counting. When you need to know the position, you can read it at any time. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved.

Rotating photoelectric encoder is a mature technology for measuring angle and length. Nowadays, using absolute encoder with high precision and large range greatly improves the measurement accuracy and reliability, and is economical and practical. At present, it is still the most choice for measuring length.

High quality Optical encoders linear Incremental encoder is commonly used, and absolute encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the...
The sine and cosine encoder is equipped with permanent magnet synchronous traction machine to achieve more accurate leveling and comfort, and the comfort effect is the same as that of DC motor drive.
Incremental encoder usually has three signal outputs (there are six signals in difference): A,B and Z, which generally adopt TTL level, A pulse is in front, B pulse is behind, A and B pulses differ by 90 degrees, and a Z pulse is sent out every turn, which can be used as a reference mechanical zero position. Generally, A leads B or A before B-ultrasound is used for direction determination. The incremental encoder of our company is defined as the clockwise rotation of the encoder as forward...

Gear sensor rotary encoder incremental The incremental rotary encoder has the difference of resolution, which is measured by the number of pulses per turn, ranging from 6 to 5400 or higher, and the more pulses, the higher the resolution; This is one of the important basis for selection.
Absolute encoder battery voltage drop: this fault usually has a clear meaning alarm, in this case, the battery needs to be replaced. If the reference point position memory is lost, the operation of returning to the reference point must be carried out.
