Encoders

Encoders are devices that are commonly used in industrial applications to take an analog or digital signal and convert it into a new form of information. There are several types of encoders, each used for different needs. Examples of popular encoders in include rotary encoders, linear encoders, and incremental encoders. Among these is the EN11-HSM1AQ20 encoder, which is a rotary encoder often used in automated systems.

The EN11-HSM1AQ20 encoder is especially suited for applications that require highly precise position and/or speed sensing. This encoder features a discreet system with high signal resolution in both the clockwise and counterclockwise directions and can be driven by a microcontroller or microcomputer for increased accuracy and sensitivity. The EN11-HSM1AQ20 encoder also has a robust housing design that is resistant to shock, dust, and moisture, making it ideal for demanding industrial applications.

The EN11-HSM1AQ20 encoder works on the principle of converting motion into digital information. The device consists of four main components: an output shaft, an encoder wheel, a light source, and a set of photo-sensors. The shaft is connected to a motor or a mechanical system so that its movements can be sensed. The encoder wheel is installed near the output shaft so that when the shaft rotates, the encoder wheel also rotates at the same speed as the output shaft.

In the center of the encoder wheel, there is a light source which is composed of three light-emitting diodes (LEDs) with intermittently positioned opaque windows. The three light sources emit light through the open window and lights up the photo-sensor, which is attached to the encoder. The photo-sensor consists of a housing with a small aperture that houses an optical sensor. As the encoder wheel turns, the locations of the open windows and opaque sections change, and the photo-sensor receives different amounts of light which changes its output signal.

The output signal of the photo-sensor is then sent to the microcontroller for further processing. The microcontroller is responsible for translating the output signal of the photo-sensors into more meaningful information, which is the number of complete rotations the encoder wheel has taken and also the direction in which the wheel has turned. The EN11-HSM1AQ20 encoder is capable of detecting angle changes as small as 1/640 or 0.0015595 degrees, making it one of the most accurate encoder models on the market.

In conclusion, the EN11-HSM1AQ20 encoder is an excellent choice for applications that require precise position and/or speed sensing. With its robust housing design and highly accurate output signals, the EN11-HSM1AQ20 encoder can be used in a variety of industrial applications ranging from automation systems to robotics.
