Encoders - DP11H3015B30S Application Field and Working Principle

Encoders are devices used in various industries to receive or transmit information from or to machines and other devices. Different types of encoders have different application fields and working principles; in this article, we will discuss the DP11H3015B30S encoder.The DP11H3015B30S encoder is used to check angles, positions, or to measure rotary speed and displacement. It is suitable for low speed operations in any industrial environment. It is most often used in applications requiring precise angle measurements and accurate detection of rotational speed and displacement.The DP11H3015B30S encoder has two signal outputs; A and B signals. The A and B output signals are different in terms of waveform, and are used to detect angular position. Specifically, the signals are out-of-phase square waves; this means that the A output signal has a phase difference of 90° with the B output signal.The DP11H3015B30S encoder utilizes a glass disk with a series of B lines which, when rotated, generates an electrical output to changes in position. This glass disk has a special optical pattern consisting of two concentric rings. The A channel of the encoder uses light sensors to detect the rotating B lines, while the B channel is positioned at 90° with the A channel and is used to detect changes in rotational speed.The way the DP11H3015B30S encoder detects angular position is impressive. The encoder works by using a single light source, which is located in the center of the glass disk. The light from this source is reflected off the glass disk and onto two light sensors, creating an electrical signal. As the disk is rotated, the reflected light intensity changes, causing a variation in the electrical current flowing through the two light sensors. The output of the two signals is used to calculate the angle of rotation.The DP11H3015B30S encoder is also equipped with a reset output, which is used to reset the encoder when a pre-set position is reached. This reset output will also shut down the motor and stop it when the angle of rotation reaches a certain position, thus ensuring accurate and consistent readings.Overall, the DP11H3015B30S encoder is an excellent choice for applications requiring precise angle measurements and accurate detection of rotational speed and displacement. Its two signal outputs and reset output allow for accurate readings and for resetting when desired. And its optical design makes it suitable for low-speed operations in any industrial environment.
