4 Main Applications Of A Quadrature Encoder

Digital encoders are known for their sheer variety to suit a range of applications and features. Be it linear encoders, shaft encoders, or angle encoders, each serves its unique purpose. Another prominent type of encoder is the quadrature encoder, whose output offers two square wave signals that are out of phase with each other. To determine what this signal means, a quadrature encoder is often paired with a quadrature decoder, which converts this signal into the exact location and speed. So what are the uses of a quadrature encoder? This blog covers 4 main applications of this digital encoder.

Industrial Applications Of A Quadrature Encoder

1. CNC Machines

CNC machines rely on quadrature encoders and decoders to determine the accuracy of the process. The cutting tool must move precisely along a predetermined path, and this action must be highly repeatable. Quadrature encoders help achieve this by offering feedback of the cutting tool and its relative position to the workpiece.

2. Conveyor Systems

Material handling equipment, such as conveyor systems, also employs quadrature encoders for tracking the position of the product on the belt, as well as the speed of the belt itself. Moreover, they can also be used to employ triggers to change speeds or stop, such as in cases of sortation or quality control.

3. Industrial Robotics

Industrial robotics has become a staple in assembly lines and manufacturing facilities. Quadrature encoders and decoders help ascertain the speed and accuracy of the robotic arms and tool position. Since robots are jointed, the digital encoders also play a vital role in tracking the joint movement to improve the overall throughput of the assembly line with minimal errors.

4. Packaging Equipment

Much like conveyor systems, quadrature encoders also serve the packaging industry by tracking the speed and movement of various equipment. This ensures that the packaging is appropriate and the labels are placed at the right location for each parcel. They are primarily used in food packaging, pharmaceuticals, and consumer goods packaging and distribution.
