Three feet of encoder

Some friends curious about three feet of the encoder, electronic science, to everyone to meet everyone's seeking knowledge desire. In fact, three feet in the middle of three feet encoder with the arrow that is adjustable side, the other two is not clearly defined. Encoder, as we all know, the main variable resistance effect or partial pressure, adjustable when the relative position changes, its resistance value with the other two feet will be corresponding change. Then, we summed up the three feet the role of the encoder to roughly the following three points: the role of a tripod encoder: can change resistance than continuous. The ends of the resistor body each terminal has a fixed arm, movable arm is among terminal. Movable arm resistance will be divided into upper and lower two parts, as it moves, a movable arm on the resistor body resistance can make the upper and lower two parts to the resistance ratio of continuous change. Three feet encoder part 2: variable pressure. The movable arm end all of the output voltage of the input voltage. Three feet encoder function: can change resistance than continuous. The ends of the resistor body each terminal has a fixed arm, movable arm is among terminal. Movable arm resistance will be divided into upper and lower two parts, as it moves, a movable arm on the resistor body resistance can make the upper and lower two parts to the resistance ratio of continuous change. Three feet of the encoder rotation encoder movable arm change partial pressure ratio, is changed to the size of the signal power amplifier level, to achieve the purpose of adjusting the volume. But there are other encoder role also similarly. Shanghai electronic tripods encoder, also have a large number of production if there is any need please contact us! Electronic encoder since 91 began to develop production, product model and more complete, widely used in automotive electronics, home electronics, multimedia, mixer, interphone, electronic toys, household, aerospace, military industry and other fields. Power suppliers, find find electronic encoder manufacturers.
