Incremental Encoder Features Of The Device

When selecting an encoder, the user must consider some of the most important application features: whether to track a linear motion or a rotary motion? Is it an optical encoder or a magnetic encoder? In addition to the successful implementation of professional applications, users should also consider the choice of incremental encoders or absolute encoders - even with the same sensing mechanism, the performance of these two encoders are also very different.Incremental Encoder

To achieve a successful application you need to understand all the relevant features of the two encoders and make the right choice.Incremental Encoder Incremental encoders require the use of additional electronic devices (usually PLCs, counters, or frequency converters) for pulse counting and to convert pulse data into velocity or motion data, while absolute encoders produce numbers that can identify absolute positions signal. In summary, incremental encoders are generally more suitable for low-performance simple applications, and absolute encoders are the best choice for more complex critical applications - these applications have higher speed and position control requirements The The output type depends on the specific application.Incremental Encoder

When the incremental encoder is moved, the encoder generates a binary pulse stream proportional to the axis rotation speed (rotary encoder) or motion distance (linear encoder). Incremental Encoder When an optical encoder is used, a particular pattern of code or a linear code strip placed between the LED light source and the optical sensor can alternately turn on or block the beam, thereby generating an analog signal; then the additional circuit (usually the onboard ASIC) Converts an analog signal to a square wave.Incremental Encoder Incremental encoders can also contain an additional channel, the index channel (or Z channel). This channel allows the rotary encoder or a linear encoder at a specific position to generate a pulse per turn (the .Z channel can be specified at a specific location. In high speed applications, using the Z channel makes it easy to indicate a single circle and Thereby calculating the speed.Incremental Encoder
