Encoder Overview An encoder is a device used to measure linear or rotary motion and speed. They are often used in robotics or mechanical engineering, where they can be used to measure position, speed, acceleration, or other movement-related information. Common types of encoders are incremental encoders, optical encoders, and rotary encoders.The DP11SVN20A20K is an incremental rotary encoder used to measure linear or rotary motion and speed. It is a single-turn encoder with a resolution of 20 pulses per revolution. This encoder uses an optical sensing method and processes an 11-bit parallel output signal.Features of the DP11SVN20A20K The DP11SVN20A20K has several important features that make it suitable for a variety of applications. It has a wide operating range, from -30°C to +70°C, and is also shock and vibration resistant. Additionally, it can operate in temperatures up to 100°C and in high humidity environments.The encoder has several output functions that can be selected in order to meet the needs of the application. These include common pulse, differential output, and self-diagnostics functions. In addition to its 11-bit parallel output signal, the encoder also has a gray code output that can be used for identification purposes. Applications of the DP11SVN20A20KThe DP11SVN20A20K is a versatile, high-performance encoder that is suitable for a variety of applications. It can be used in robotics, mechanical engineering, and factory automation. It is particularly well-suited for high-speed, precision applications such as printing presses and machine tools as well as winding machines and other servomotor applications.The encoder can also be used in automotive applications, such as engine and ABS control systems. Additionally, the device is useful for speed monitoring on conveyers, packaging machines, and material handling equipment.Working Principle of the DP11SVN20A20KThe DP11SVN20A20K uses an optoelectronic sensing method to measure linear or rotary motion and speed. The encoder has a precision-machined 8-groove optical code disk with a resolution of 20 pulses per revolution.When the disk rotates, the light sources in the encoder emit light onto the code disk, which is reflected back to the detector. There are three sets of detectors that each have two components: an LED light source and a phototransistor.The phototransistor converts the reflected light into a digital signal that is then converted to an 11-bit parallel output signal. This output signal is then sent to an appropriate controller, such as a PLC, where the signal can be converted into a velocity or position measurement.ConclusionThe DP11SVN20A20K is a high-performance incremental rotary encoder that is suitable for a wide variety of applications. It is generally used in robotics, mechanical engineering, and factory automation, as well as automotive and speed monitoring uses. The encoder uses an optoelectronic sensing method and processes an 11-bit parallel output signal.
