German SIEMENS encoder SIEMENS model SIEMENS price

SIEMENS encoders provide an absolutely unique position, are interference-resistant, and do not require power-loss memory. They are increasingly widely used for angle and length measurement and positioning control in various industrial systems. Absolute rotary optical encoders, due to their absolutely unique position, interference resistance, and lack of need for power-loss memory, are increasingly widely used for angle and length measurement and positioning control in various industrial systems. The optical code disk of an absolute encoder has many tracks, with each track arranged sequentially as 2 line, 4 line, 8 line, 16 line, and so on. Thus, 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 a n-bit absolute encoder. Such an encoder is determined by the mechanical position of the code disk and is unaffected by power outages or interference. The uniqueness of each position in an absolute encoder is determined by its mechanical position; it requires no memory, no reference point search, and no continuous counting. The position is read only when needed. This significantly improves the encoder's interference resistance and data reliability. Since absolute encoders are clearly superior to incremental encoders in positioning, they are increasingly used in industrial control positioning. Due to their high precision and large number of output bits, if parallel output were still used for absolute encoders, every bit of the output signal would need to ensure a good connection, and isolation would be required for complex operating conditions. The large number of cable cores would cause considerable inconvenience and reduce reliability. Therefore, for multi-bit output types, absolute encoders generally use serial or bus-type output. For absolute encoders produced in Germany, the most common serial output is SSI (Synchronous Serial Interface). A single-turn absolute rotary encoder measures the tracks on the optical code disk during rotation to obtain a unique code. When rotation exceeds 360 degrees, the code returns to the origin, which violates the principle of absolute encoding uniqueness. Such encoders can only be used for measurements within a rotation range of 360 degrees and are called single-turn absolute encoders. To measure rotation beyond a 360-degree range, a multi-turn absolute encoder is required. Manufacturers of absolute encoders use the mechanical principle of clock gears. As the central code disk rotates, another set of code disks (or multiple sets of gears and code disks) is driven via gear transmission. This adds turn-count coding to the single-turn coding, thereby expanding the encoder's measurement range. Such absolute encoders are called multi-turn absolute encoders. They also determine the code by mechanical position, ensuring each position code is unique and non-repeating without the need for memory. Another advantage of multi-turn encoders is that the large measurement range often provides considerable margin in actual use. This eliminates the need for tedious zero-point finding during installation; an intermediate position can be used as the starting point, greatly simplifying installation and commissioning. Multi-turn absolute encoders have clear advantages in length positioning and are increasingly used in industrial control positioning.

SIEMENS encoder installation and use

Mechanical installation and use of absolute rotary encoders: Mechanical installation of absolute rotary encoders includes 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 via gear connection). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, and the motor rotation falls within this range, the full range can be utilized to improve resolution. The disadvantage is that motion through reduction gears introduces backlash error during forward and reverse travel. It is generally used for unidirectional high-precision control positioning, such as roll gap control in steel rolling. Additionally, if the encoder is installed directly on the high-speed end, motor vibration must be minimal; otherwise, the encoder may be 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. It is generally used for long-distance positioning measurements, such as in various lifting equipment and feed cart positioning. Auxiliary mechanical installation: Common methods include rack and pinion, chain and belt, friction wheels, and rope retraction mechanisms.

SIEMENS encoder application areas

Compared with traditional optical and grating encoders, magneto-electric encoders offer better resistance to vibration, corrosion, contamination, and interference, as well as a wider temperature range. They can be applied in fields where traditional optical encoders cannot adapt. Magnetic encoders are specifically designed for extremely harsh environments, which generally require wide temperature characteristics, the ability to withstand strong vibration and shock, and a high protection rating. In addition, we offer reliable signal output circuits and simple installation methods, which can greatly reduce losses from downtime. They are typically used in metallurgy, papermaking, and woodworking machinery. High-performance magnetic encoders are widely used in industrial control, mechanical manufacturing, ships, textiles, printing, aviation, aerospace, radar, communications, military industry, and other fields.

SIEMENS encoder hybrid type

A hybrid absolute encoder outputs two sets of information: one set detects the magnetic pole position and provides absolute information functionality; the other set is identical to the output information of an incremental encoder. An optical encoder is an angle (angular velocity) detection device. It converts the angular input to the shaft into corresponding electrical pulses or digital values using the photoelectric conversion principle. It offers advantages such as small size, high precision, reliable operation, and digital interfaces. It is widely used in devices and equipment requiring angle detection, such as CNC machine tools, rotary tables, servo drives, robots, radar, and military target determination.
