　　The price of encoders ranges from a few dozen yuan to tens of thousands of yuan, depending on the following factors:

　　Zero-width non-joiner character (U+200C) — original character retained. Type Encoders come in various types, such as rotary encoders, linear encoders, optical encoders, and magnetic encoders. These different types vary in technology and applications, and their prices also differ accordingly.

　　Zero-width non-joiner character (U+200C) — original character retained. Brand Encoders from well-known brands such as Siemens, Panasonic, Omron, and Renishaw typically command higher prices due to their assured quality and robust technical support. In contrast, encoders from domestic or lesser‑known brands may be offered at relatively lower price points.

　　Zero-width non-joiner character (U+200C) — original character retained. Specifications The encoder’s specifications—such as accuracy, resolution, output signal type (e.g., analog or digital), and protection rating—also influence its price. High‑accuracy, high‑resolution encoders naturally command a higher price.

　　Zero-width non-joiner character (U+200C) — original character retained. Market supply : Market supply and demand also influence encoder prices. When a particular type of encoder is in short supply, its price may rise; conversely, if supply exceeds demand, prices may fall.

　　Specific price example

　　Based on actual market sales, here are some example prices for encoders (for reference only):

　　Zero-width non-joiner character (U+200C) — original character retained. Economical encoder : Some economical or entry-level encoders, such as rotary encoders for simple applications, may cost anywhere from a few dozen to several hundred yuan.

　　Zero-width non-joiner character (U+200C) — original character retained. Mid-to-high-end encoder : Mid- to high-end encoders featuring high precision, high resolution, and robust protection ratings can range in price from several thousand to tens of thousands of yuan. In particular, encoders used in advanced applications such as industrial automation, robotics, and CNC machine tools generally command higher prices.

　　Working principle

　　Zero-width non-joiner character (U+200C) — original character retained. Absolute encoder By reading the on/off states of each groove on the optical encoder disc, a unique binary code—such as Gray code—is obtained, thereby directly determining the absolute position. This encoding scheme ensures that, at any given moment, the encoder’s position can be instantly determined simply by reading it, without the need to reference an initial point or perform cumulative calculations.

　　Zero-width non-joiner character (U+200C) — original character retained. Incremental encoder It generates signals based on rotational motion, determining the direction of rotation and establishing the reference point by outputting three sets of square‑wave pulses—A, B, and Z. The A and B pulses are 90° out of phase, enabling detection of the rotation direction; the Z pulse produces one pulse per revolution, serving as the reference point. Incremental encoders determine position by counting the number of pulses, but after a power loss or system reboot, they must re‑acquire the home or reference position to resume accurate positioning.

　　Memory function

　　Zero-width non-joiner character (U+200C) — original character retained. Absolute encoder : It features memory functionality, ensuring that axis position data is not lost even in the event of a power failure or other interruptions. Upon power restoration, the encoder can immediately report its current position.

　　Zero-width non-joiner character (U+200C) — original character retained. Incremental encoder : In the event of a power failure or other interruption, axis position information is lost. Upon re-powering, it is necessary to restore the home or reference point either via an external device (such as a limit switch) or through manual operation.

　　Structure and Composition

　　Zero-width non-joiner character (U+200C) — original character retained. Absolute encoder : The optical encoder disc features numerous optical channels etched into its surface, with each channel arranged according to a distinct number of lines, thereby generating a unique binary code. Internally, the encoder also comprises a light source, photosensitive elements, and decoding circuitry, among other components.

　　Zero-width non-joiner character (U+200C) — original character retained. Incremental encoder It typically consists of an optoelectronic code disk with a central axis, which reads signals via optoelectronic transmitting and receiving components. The code disk is engraved with equally spaced light-transmitting slots or reflective surfaces to generate pulse signals.
