German LEINE LINDE encoder, LEINE LINDE model, LEINE LINDE price

The LEINE LINDE encoder has many optical channel tracks. Each track is arranged sequentially with 2 lines, 4 lines, 8 lines, and 16 lines. In this way, at each position of the encoder, by reading the light and dark states of each track, a unique 2-ary code (Gray code) is obtained, ranging from the zeroth power of 2 to the n-1th power of 2. This is called an n-bit absolute encoder. Such encoders use an optical code disk for memory. The absolute encoder determines the code based on mechanical position; it does not require memory, does not need to find a reference point, and does not need continuous counting. Whenever the position needs to be known, its position is read. In this way, the anti-interference characteristics and data reliability of the encoder are greatly improved. From single-turn absolute encoders to multi-turn absolute encoders: in an absolute rotary single-turn absolute encoder, the tracks of the optical code disk are measured during rotation to obtain a unique code. When the rotation exceeds 360 degrees, the code returns to the origin, which does not comply with the principle of uniqueness for absolute encoding. Such encoding can only be used for measurements within a rotation range of 360 degrees and is called a single-turn absolute encoder.

LEINE LINDE encoder installation and usage

Mechanical installation of absolute rotary encoders includes various forms such as high-speed end installation, low-speed end installation, and auxiliary mechanical device installation. High-speed end installation: installed at the drive motor shaft end (or gear connection). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, and the number of motor rotations falls within this range, the full range can be utilized to improve resolution. The disadvantage is that there is gear backlash error during forward and reverse motion after passing through reduction gears. It is generally used for unidirectional high-precision control positioning, such as roll gap control in steel rolling. Additionally, if the encoder is directly installed on the high-speed end, motor vibration must be minimal; otherwise, the encoder is easily damaged. Low-speed end installation: installed after the reduction gear, such as at the shaft end of a hoist wire rope drum or the last stage of the reduction gear shaft. This method eliminates gear backlash, provides more direct measurement, and offers higher accuracy. This method is generally used for long-distance positioning measurements, such as various lifting equipment and feed cart positioning. Auxiliary mechanical installation: common methods include rack and pinion, chain and belt, friction wheels, and rope reeling mechanisms.

LEINE LINDE encoder advantages

Compact size, high bai precision. The du itself can have very high resolution, with no contact and no wear. The same zhi type can detect angular displacement and, with the help of dao mechanical conversion devices, linear displacement. Multi-turn optical absolute encoders can detect linear displacement over a considerable range (such as 25-bit multi-turn). Long service life, flexible installation, rich interface options, and reasonable price. Mature technology, widely used domestically and internationally for many years. Disadvantages: although precise, they impose higher protection requirements for outdoor and harsh environment use; measuring linear displacement relies on mechanical device conversion, requiring elimination of errors caused by mechanical gaps; it is difficult to overcome slip when detecting objects moving on rails. Advantages of magnetostrictive absolute encoders: moderate size, direct measurement of linear displacement, absolute digital encoding, theoretically unlimited range; no contact, no wear, resistant to harsh environments, usable underwater up to 1000 meters; rich interface options and diverse measurement methods.

LEINE LINDE encoder selection considerations

1) Mechanical installation dimensions: including locating spigot, shaft diameter, mounting hole positions; cable outlet direction; installation space volume; whether the working environment protection rating meets requirements. 2) Resolution: i.e., the number of pulses output per revolution when the encoder is operating, and whether it meets the design accuracy requirements. 3) Electrical interface: Common encoder output methods include push-pull output (F type HTL format), voltage output (E), open collector (C, commonly C is NPN transistor output, C2 is PNP transistor output), and line driver output. The output method should match the interface circuit of its control system.
