1. Material: Electronic components + PCB2. Working voltage: 5V3. Number of pulses per revolution: 204. The rotary encoder can count the number of output pulses during rotation in the forward and reverse directions by rotation. Unlike the potentiometer, the rotation count is unlimited. With the buttons on the rotary encoder, it can be reset to the initial state, that is, counting from 0.5. Working principle: The incremental encoder is a rotary sensor that converts the rotational displacement into a series of digital pulse signals. These pulses are used to control angular displacement. The conversion of angular displacement in the Eltra encoder uses the photoelectric scanning principle. The reading system is based on the rotation of the radial index disc (code disc) composed of alternating light-transmitting windows and opaque windows, and is simultaneously illuminated vertically by an infrared light source, and the light projects the image of the code disc onto the surface of the receiver . The receiver is covered with a layer of diffraction grating, which has the same window width as the code wheel. The receivers job is to feel the changes produced by the rotation of the disc, and then convert the light changes into corresponding electrical changes. Then the low-level signal is raised to a higher level, and a square pulse without any interference is generated, which must be handled by an electronic circuit. The reading system usually uses a differential method, that is, comparing two different signals with the same waveform but a phase difference of 180 ° in order to improve the quality and stability of the output signal. The reading is formed based on the difference between the two signals, thereby eliminating interference.Specification: Package Weight One Package Weight 0.10kgs / 0.23lb One Package Size 15cm * 18cm * 12cm / 5.91inch * 7.09inch * 4.72inch Qty per Carton 224 Carton Weight 30.00kgs / 66.14lb Carton Size 50cm * 50cm * 60cm / 19.69inch * 19.69inch * 23.62inch Loading Container 20GP: 177 cartons * 224 pcs = 39648 pcs40HQ: 412 cartons * 224 pcs = 92288 pcs
