German BAUMUELLER encoder BAUMUELLER model BAUMUELLER price

The BAUMUELLER 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-base 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 requires no memory, no reference point search, and no continuous counting. Whenever the position needs to be known, its position is read directly. This greatly improves the encoder's anti-interference characteristics and data reliability. From single-turn absolute encoders to multi-turn absolute encoders: 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 uniqueness in 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.

BAUMUELLER Encoder Introduction

A detector that outputs angular data within one motor revolution to an external target. Absolute encoders can generally output 360 ° with a resolution of 8 to 12 bits. Incremental encoders have a disadvantage: they lose axis position in the event of a power failure. However, absolute encoders do not lose axis position even if a power failure occurs. They can output various codes, such as binary code and BCD code. Absolute encoders are more expensive, more precise, and larger than incremental encoders. The optical code disk of an absolute encoder has many light channel tracks; each track is arranged sequentially with 2 lines, 4 lines, 8 lines, and 16 lines. At each position of the encoder, by reading the light and dark states of each track, a unique 2-base code (Gray code) is obtained, ranging from the zeroth power of 2 to the n-1th power of 2. The absolute encoder determines the code based on mechanical position; it requires no memory, no reference point search, and no continuous counting. The position is read only when needed. Absolute encoders have a measuring range and are suitable for use in certain special machine tools.

BAUMUELLER Encoder Component Differences

From single-turn absolute encoders to multi-turn absolute encoders. 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 uniqueness in 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. For measuring rotation beyond the 360 degree range, multi-turn absolute encoders are used. Encoder production employs clock gear mechanics. When the central code disk rotates, another set of code disks (or multiple sets of gears and code disks) is driven via gears. On the basis of single-turn encoding, turn-count encoding is added to expand the measurement range of the encoder. Such absolute encoders are called multi-turn absolute encoders. They also determine the code based on mechanical position, ensuring each position code is unique and non-repeating without requiring memory. Another advantage of multi-turn encoders is that due to the large measurement range, there is often considerable margin. Therefore, during installation, it is not necessary to struggle to find the zero point; any intermediate position can serve as the starting point, greatly simplifying installation and commissioning.
