Additional Channels For Incremental Encoder

When an incremental encoder is moved, the encoder produces a binary pulse flow proportional to the axis rotation speed (Rotary encoder) or motion distance (linear encoder). When the optical encoder is used, the specific pattern of the encoder or the linear band which is placed between the LED light source and the light sensor can alternately guide or block the beam, resulting in an analog signal, and the extra circuit (usually the onboard ASIC) converts the analog signal to a square wave.Incremental Encoder 

A magnetic encoder can operate in a variety of mechanisms, but it rotates a magnetic field, resulting in a voltage pulse or a change in the resistance that can be converted to a pulse.Incremental Encoder

An incremental encoder can also contain an additional channel, the index channel (or Z-Channel). The channel generates a pulse for Each loop of the rotary encoder or linear encoder at a particular position. The z-channel can determine a specific location at startup. In high-speed applications, the use of the Z-channel can be easily used to indicate a single lap, and thus calculate the rotational speed. Incremental encoders are generally only applicable to simple applications, whether the control device is counter, PLC or inverter, directly connected to the encoder and controller can be.Incremental Encoder

No encoders are available for all applications, and you need to choose the right encoder based on your application requirements. Incremental encoders are easy to integrate and maintain. In less complex applications, where cost is a major concern for users, incremental encoders are the best choice, and incremental encoders are often used for speed or rate monitoring, such as adjusting the line speeds of conveyors in warehouses or mail-sorting facilities.Incremental Encoder 

Depending on whether the application needs to control the direction of movement, you may decide to use a single channel incremental encoder or an orthogonal encoder.Incremental Encoder
