German EMETA encoder EMETA model EMETA price

EMETA encoders are used to measure physical quantities such as speed, position, velocity, or angle bai du zhi. They are sensors that convert mechanical displacement into electrical signals and are classified into incremental and absolute types. Incremental encoders generate pulse signals, and the number of pulses can be used to measure speed, length, or position. For absolute encoders, each position corresponds to a digital value of displacement. Inside the encoder, there is a rotating disk (code disk) with several transparent and opaque windows. Photodetectors collect intermittent light beams, thereby converting light pulses into electrical pulses, which are then processed and output by electronic output circuits.

EMETA Encoder Introduction

A detector that outputs angular data within one motor revolution to an external target. Absolute encoders can generally output 360 ° with 8 to 12 bits. Incremental encoders have a disadvantage: axis position is lost in the event of a power failure. However, for absolute encoders, axis position is not lost even if a power failure occurs. Various codes can be output, 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-ary 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 whenever it is needed. Absolute encoders have a measuring range and are suitable for use in certain special machine tools.

EMETA Encoder Application Areas

Compared with traditional photoelectric and grating encoders, magneto-electric encoders offer better resistance to vibration, corrosion, contamination, and interference, as well as a wider temperature range, making them suitable for applications where traditional photoelectric 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 high protection ratings. In addition, we offer reliable signal output circuits and simple installation methods, which can significantly reduce losses due to 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.

EMETA Encoder Applications

This encoder uses relative counting for position measurement. Before operation, the pulse counts corresponding to various signals, such as speed change points, leveling points, and braking stop points, are stored in respective memory units via programming. During elevator operation, the rotary encoder detects and software calculates the following signals in real time: elevator floor position, speed change point position, and leveling point position, thereby performing floor counting and issuing speed change and leveling signals.
